AlertmanagerList is a list of Alertmanager
APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources
List of alertmanagers. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md
No Additional ItemsThe Alertmanager custom resource definition (CRD) defines a desired Alertmanager setup to run in a Kubernetes cluster. It allows to specify many options such as the number of replicas, persistent storage and many more.
For each Alertmanager resource, the Operator deploys a StatefulSet in the same namespace. When there are two or more configured replicas, the Operator runs the Alertmanager instances in high-availability mode.
The resource defines via label and namespace selectors which AlertmanagerConfig objects should be associated to the deployed Alertmanager instances.

Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
Standard object's metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata
Annotations is an unstructured key value map stored with a resource that may be set by external tools to store and retrieve arbitrary metadata. They are not queryable and should be preserved when modifying objects. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/annotations
Each additional property must conform to the following schema
Type: stringCreationTimestamp is a timestamp representing the server time when this object was created. It is not guaranteed to be set in happens-before order across separate operations. Clients may not set this value. It is represented in RFC3339 form and is in UTC.
Populated by the system. Read-only. Null for lists. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata
Number of seconds allowed for this object to gracefully terminate before it will be removed from the system. Only set when deletionTimestamp is also set. May only be shortened. Read-only.
DeletionTimestamp is RFC 3339 date and time at which this resource will be deleted. This field is set by the server when a graceful deletion is requested by the user, and is not directly settable by a client. The resource is expected to be deleted (no longer visible from resource lists, and not reachable by name) after the time in this field, once the finalizers list is empty. As long as the finalizers list contains items, deletion is blocked. Once the deletionTimestamp is set, this value may not be unset or be set further into the future, although it may be shortened or the resource may be deleted prior to this time. For example, a user may request that a pod is deleted in 30 seconds. The Kubelet will react by sending a graceful termination signal to the containers in the pod. After that 30 seconds, the Kubelet will send a hard termination signal (SIGKILL) to the container and after cleanup, remove the pod from the API. In the presence of network partitions, this object may still exist after this timestamp, until an administrator or automated process can determine the resource is fully terminated. If not set, graceful deletion of the object has not been requested.
Populated by the system when a graceful deletion is requested. Read-only. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata
Must be empty before the object is deleted from the registry. Each entry is an identifier for the responsible component that will remove the entry from the list. If the deletionTimestamp of the object is non-nil, entries in this list can only be removed. Finalizers may be processed and removed in any order. Order is NOT enforced because it introduces significant risk of stuck finalizers. finalizers is a shared field, any actor with permission can reorder it. If the finalizer list is processed in order, then this can lead to a situation in which the component responsible for the first finalizer in the list is waiting for a signal (field value, external system, or other) produced by a component responsible for a finalizer later in the list, resulting in a deadlock. Without enforced ordering finalizers are free to order amongst themselves and are not vulnerable to ordering changes in the list.
GenerateName is an optional prefix, used by the server, to generate a unique name ONLY IF the Name field has not been provided. If this field is used, the name returned to the client will be different than the name passed. This value will also be combined with a unique suffix. The provided value has the same validation rules as the Name field, and may be truncated by the length of the suffix required to make the value unique on the server.
If this field is specified and the generated name exists, the server will return a 409.
Applied only if Name is not specified. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#idempotency
A sequence number representing a specific generation of the desired state. Populated by the system. Read-only.
Map of string keys and values that can be used to organize and categorize (scope and select) objects. May match selectors of replication controllers and services. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/labels
Each additional property must conform to the following schema
Type: stringManagedFields maps workflow-id and version to the set of fields that are managed by that workflow. This is mostly for internal housekeeping, and users typically shouldn't need to set or understand this field. A workflow can be the user's name, a controller's name, or the name of a specific apply path like "ci-cd". The set of fields is always in the version that the workflow used when modifying the object.
No Additional ItemsManagedFieldsEntry is a workflow-id, a FieldSet and the group version of the resource that the fieldset applies to.
APIVersion defines the version of this resource that this field set applies to. The format is "group/version" just like the top-level APIVersion field. It is necessary to track the version of a field set because it cannot be automatically converted.
FieldsType is the discriminator for the different fields format and version. There is currently only one possible value: "FieldsV1"
FieldsV1 holds the first JSON version format as described in the "FieldsV1" type.
Manager is an identifier of the workflow managing these fields.
Operation is the type of operation which lead to this ManagedFieldsEntry being created. The only valid values for this field are 'Apply' and 'Update'.
Subresource is the name of the subresource used to update that object, or empty string if the object was updated through the main resource. The value of this field is used to distinguish between managers, even if they share the same name. For example, a status update will be distinct from a regular update using the same manager name. Note that the APIVersion field is not related to the Subresource field and it always corresponds to the version of the main resource.
Time is the timestamp of when the ManagedFields entry was added. The timestamp will also be updated if a field is added, the manager changes any of the owned fields value or removes a field. The timestamp does not update when a field is removed from the entry because another manager took it over.
Same definition as creationTimestampName must be unique within a namespace. Is required when creating resources, although some resources may allow a client to request the generation of an appropriate name automatically. Name is primarily intended for creation idempotence and configuration definition. Cannot be updated. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names#names
Namespace defines the space within which each name must be unique. An empty namespace is equivalent to the "default" namespace, but "default" is the canonical representation. Not all objects are required to be scoped to a namespace - the value of this field for those objects will be empty.
Must be a DNS_LABEL. Cannot be updated. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/namespaces
List of objects depended by this object. If ALL objects in the list have been deleted, this object will be garbage collected. If this object is managed by a controller, then an entry in this list will point to this controller, with the controller field set to true. There cannot be more than one managing controller.
No Additional ItemsOwnerReference contains enough information to let you identify an owning object. An owning object must be in the same namespace as the dependent, or be cluster-scoped, so there is no namespace field.
API version of the referent.
If true, AND if the owner has the "foregroundDeletion" finalizer, then the owner cannot be deleted from the key-value store until this reference is removed. See https://kubernetes.io/docs/concepts/architecture/garbage-collection/#foreground-deletion for how the garbage collector interacts with this field and enforces the foreground deletion. Defaults to false. To set this field, a user needs "delete" permission of the owner, otherwise 422 (Unprocessable Entity) will be returned.
If true, this reference points to the managing controller.
Kind of the referent. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds

UID of the referent. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names#uids
An opaque value that represents the internal version of this object that can be used by clients to determine when objects have changed. May be used for optimistic concurrency, change detection, and the watch operation on a resource or set of resources. Clients must treat these values as opaque and passed unmodified back to the server. They may only be valid for a particular resource or set of resources.
Populated by the system. Read-only. Value must be treated as opaque by clients and . More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#concurrency-control-and-consistency
Deprecated: selfLink is a legacy read-only field that is no longer populated by the system.
UID is the unique in time and space value for this object. It is typically generated by the server on successful creation of a resource and is not allowed to change on PUT operations.

operator provisions a minimal Alertmanager configuration with one empty
receiver (effectively dropping alert notifications).
containers allows injecting additional containers. This is meant to
allow adding an authentication proxy to an Alertmanager pod.
Containers described here modify an operator generated container if they
share the same name and modifications are done via a strategic merge
patch. The current container names are: alertmanager and
config-reloader. Overriding containers is entirely outside the scope
of what the maintainers will support and by doing so, you accept that
this behaviour may break at any time without notice.
A single application container that you want to run within a pod.
Arguments to the entrypoint.
The container image's CMD is used if this is not provided.
Variable references $(VARNAME) are expanded using the container's environment. If a variable
cannot be resolved, the reference in the input string will be unchanged. Double $$ are reduced
to a single $, which allows for escaping the $(VARNAME) syntax: i.e. "$$(VARNAME)" will
produce the string literal "$(VARNAME)". Escaped references will never be expanded, regardless
of whether the variable exists or not. Cannot be updated.

More info: https://kubernetes.io/docs/concepts/containers/container-lifecycle-hooks/#container-hooks
Exec specifies a command to execute in the container.
Command is the command line to execute inside the container, the working directory for the
command is root ('/') in the container's filesystem. The command is simply exec'd, it is
not run inside a shell, so traditional shell instructions ('|', etc) won't work. To use
a shell, you need to explicitly call out to that shell.
Exit status of 0 is treated as live/healthy and non-zero is unhealthy.
HTTPGet specifies an HTTP GET request to perform.

lifecycle hooks will fail at runtime when it is specified.
Optional: Host name to connect to, defaults to the pod IP.
Number or name of the port to access on the container.
Number must be in the range 1 to 65535.
Name must be an IANASVCNAME.
PreStop is called immediately before a container is terminated due to an
API request or management event such as liveness/startup probe failure,
preemption, resource contention, etc. The handler is not called if the
container crashes or exits. The Pod's termination grace period countdown begins before the
PreStop hook is executed. Regardless of the outcome of the handler, the
container will eventually terminate within the Pod's termination grace
period (unless delayed by finalizers). Other management of the container blocks until the hook completes
or until the termination grace period is reached.

DynamicResourceAllocation feature gate.
This field is immutable. It can only be set for containers.
ResourceClaim references one entry in PodSpec.ResourceClaims.
Name must match the name of one entry in pod.spec.resourceClaims of
the Pod where this field is used. It makes that resource available
inside a container.

only the result of this request.
Limits describes the maximum amount of compute resources allowed.
More info: https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/
Each additional property must conform to the following schema

RestartPolicy defines the restart behavior of individual containers in a pod.
This overrides the pod-level restart policy. When this field is not specified,
the restart behavior is defined by the Pod's restart policy and the container type.
Additionally, setting the RestartPolicy as "Always" for the init container will
have the following effect:
this init container will be continually restarted on
exit until all regular containers have terminated. Once all regular
containers have completed, all init containers with restartPolicy "Always"
will be shut down. This lifecycle differs from normal init containers and
is often referred to as a "sidecar" container. Although this init
container still starts in the init container sequence, it does not wait
for the container to complete before proceeding to the next init
container. Instead, the next init container starts immediately after this
init container is started, or after any startupProbe has successfully
completed.
Represents a list of rules to be checked to determine if the
container should be restarted on exit. The rules are evaluated in
order. Once a rule matches a container exit condition, the remaining
rules are ignored. If no rule matches the container exit condition,
the Container-level restart policy determines the whether the container
is restarted or not. Constraints on the rules:
- At most 20 rules are allowed.
- Rules can have the same action.
- Identical rules are not forbidden in validations.
When rules are specified, container MUST set RestartPolicy explicitly
even it if matches the Pod's RestartPolicy.
ContainerRestartRule describes how a container exit is handled.
Specifies the action taken on a container exit if the requirements
are satisfied. The only possible value is "Restart" to restart the
container.
Represents the exit codes to check on container exits.
Represents the relationship between the container exit code(s) and the
specified values. Possible values are:
- In: the requirement is satisfied if the container exit code is in the
set of specified values.
- NotIn: the requirement is satisfied if the container exit code is
not in the set of specified values.
Specifies the set of values to check for container exit codes.
At most 255 elements are allowed.

Processes in privileged containers are essentially equivalent to root on the host.
Defaults to false.
Note that this field cannot be set when spec.os.name is windows.
procMount denotes the type of proc mount to use for the containers.
The default value is Default which uses the container runtime defaults for
readonly paths and masked paths.
This requires the ProcMountType feature flag to be enabled.
Note that this field cannot be set when spec.os.name is windows.
Whether this container has a read-only root filesystem.
Default is false.
Note that this field cannot be set when spec.os.name is windows.
The GID to run the entrypoint of the container process.
Uses runtime default if unset.
May also be set in PodSecurityContext. If set in both SecurityContext and
PodSecurityContext, the value specified in SecurityContext takes precedence.
Note that this field cannot be set when spec.os.name is windows.
Indicates that the container must run as a non-root user.
If true, the Kubelet will validate the image at runtime to ensure that it
does not run as UID 0 (root) and fail to start the container if it does.
If unset or false, no such validation will be performed.
May also be set in PodSecurityContext. If set in both SecurityContext and
PodSecurityContext, the value specified in SecurityContext takes precedence.

Role is a SELinux role label that applies to the container.
Type is a SELinux type label that applies to the container.
User is a SELinux user label that applies to the container.
The seccomp options to use by this container. If seccomp options are
provided at both the pod & container level, the container options
override the pod options.
Note that this field cannot be set when spec.os.name is windows.
localhostProfile indicates a profile defined in a file on the node should be used.
The profile must be preconfigured on the node to work.
Must be a descending path, relative to the kubelet's configured seccomp profile location.
Must be set if type is "Localhost". Must NOT be set for any other type.
The Windows specific settings applied to all containers.
If unspecified, the options from the PodSecurityContext will be used.
If set in both SecurityContext and PodSecurityContext, the value specified in SecurityContext takes precedence.
Note that this field cannot be set when spec.os.name is linux.
GMSACredentialSpec is where the GMSA admission webhook
(https://github.com/kubernetes-sigs/windows-gmsa) inlines the contents of the
GMSA credential spec named by the GMSACredentialSpecName field.
GMSACredentialSpecName is the name of the GMSA credential spec to use.
HostProcess determines if a container should be run as a 'Host Process' container.
All of a Pod's containers must have the same effective HostProcess value
(it is not allowed to have a mix of HostProcess containers and non-HostProcess containers).
In addition, if HostProcess is true then HostNetwork must also be set to true.
The UserName in Windows to run the entrypoint of the container process.
Defaults to the user specified in image metadata if unspecified.
May also be set in PodSecurityContext. If set in both SecurityContext and
PodSecurityContext, the value specified in SecurityContext takes precedence.
StartupProbe indicates that the Pod has successfully initialized.
If specified, no other probes are executed until this completes successfully.
If this probe fails, the Pod will be restarted, just as if the livenessProbe failed.
This can be used to provide different probe parameters at the beginning of a Pod's lifecycle,
when it might take a long time to load data or warm a cache, than during steady-state operation.
This cannot be updated.
More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle#container-probes
Exec specifies a command to execute in the container.
Command is the command line to execute inside the container, the working directory for the
command is root ('/') in the container's filesystem. The command is simply exec'd, it is
not run inside a shell, so traditional shell instructions ('|', etc) won't work. To use
a shell, you need to explicitly call out to that shell.
Exit status of 0 is treated as live/healthy and non-zero is unhealthy.
Minimum consecutive failures for the probe to be considered failed after having succeeded.
Defaults to 3. Minimum value is 1.
GRPC specifies a GRPC HealthCheckRequest.
Port number of the gRPC service. Number must be in the range 1 to 65535.

Optional: Host name to connect to, defaults to the pod IP.
Number or name of the port to access on the container.
Number must be in the range 1 to 65535.
Name must be an IANASVCNAME.
Optional duration in seconds the pod needs to terminate gracefully upon probe failure.
The grace period is the duration in seconds after the processes running in the pod are sent
a termination signal and the time when the processes are forcibly halted with a kill signal.
Set this value longer than the expected cleanup time for your process.
If this value is nil, the pod's terminationGracePeriodSeconds will be used. Otherwise, this
value overrides the value provided by the pod spec.
Value must be non-negative integer. The value zero indicates stop immediately via
the kill signal (no opportunity to shut down).
This is a beta field and requires enabling ProbeTerminationGracePeriod feature gate.
Minimum value is 1. spec.terminationGracePeriodSeconds is used if unset.
Number of seconds after which the probe times out.
Defaults to 1 second. Minimum value is 1.
More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle#container-probes
Whether this container should allocate a buffer for stdin in the container runtime. If this
is not set, reads from stdin in the container will always result in EOF.
Default is false.
Whether the container runtime should close the stdin channel after it has been opened by
a single attach. When stdin is true the stdin stream will remain open across multiple attach
sessions. If stdinOnce is set to true, stdin is opened on container start, is empty until the
first client attaches to stdin, and then remains open and accepts data until the client disconnects,
at which time stdin is closed and remains closed until the container is restarted. If this
flag is false, a container processes that reads from stdin will never receive an EOF.
Default is false
Optional: Path at which the file to which the container's termination message
will be written is mounted into the container's filesystem.
Message written is intended to be brief final status, such as an assertion failure message.
Will be truncated by the node if greater than 4096 bytes. The total message length across
all containers will be limited to 12kb.
Defaults to /dev/termination-log.
Cannot be updated.
Indicate how the termination message should be populated. File will use the contents of
terminationMessagePath to populate the container status message on both success and failure.
FallbackToLogsOnError will use the last chunk of container log output if the termination
message file is empty and the container exited with an error.
The log output is limited to 2048 bytes or 80 lines, whichever is smaller.
Defaults to File.
Cannot be updated.
Whether this container should allocate a TTY for itself, also requires 'stdin' to be true.
Default is false.
volumeDevices is the list of block devices to be used by the container.
No Additional ItemsvolumeDevice describes a mapping of a raw block device within a container.
devicePath is the path inside of the container that the device will be mapped to.
name must match the name of a persistentVolumeClaim in the pod
Pod volumes to mount into the container's filesystem.
Cannot be updated.
VolumeMount describes a mounting of a Volume within a container.
Path within the container at which the volume should be mounted. Must
not contain ':'.
mountPropagation determines how mounts are propagated from the host
to container and the other way around.

This field is beta in 1.10.
When RecursiveReadOnly is set to IfPossible or to Enabled, MountPropagation must be None or unspecified
(which defaults to None).
This must match the Name of a Volume.
Mounted read-only if true, read-write otherwise (false or unspecified).
Defaults to false.
RecursiveReadOnly specifies whether read-only mounts should be handled
recursively.
If ReadOnly is false, this field has no meaning and must be unspecified.
If ReadOnly is true, and this field is set to Disabled, the mount is not made
recursively read-only. If this field is set to IfPossible, the mount is made
recursively read-only, if it is supported by the container runtime. If this
field is set to Enabled, the mount is made recursively read-only if it is
supported by the container runtime, otherwise the pod will not be started and
an error will be generated to indicate the reason.
If this field is set to IfPossible or Enabled, MountPropagation must be set to
None (or be unspecified, which defaults to None).
If this field is not specified, it is treated as an equivalent of Disabled.
Path within the volume from which the container's volume should be mounted.
Defaults to "" (volume's root).
Expanded path within the volume from which the container's volume should be mounted.
Behaves similarly to SubPath but environment variable references $(VAR_NAME) are expanded using the container's environment.

SubPathExpr and SubPath are mutually exclusive.
Container's working directory.
If not specified, the container runtime's default will be used, which
might be configured in the container image.

Must be at least 1 characters long
dnsPolicy defines the DNS policy for the pods.
enableFeatures defines the Alertmanager's feature flags. By default, no features are enabled.
Enabling features which are disabled by default is entirely outside the
scope of what the maintainers will support and by doing so, you accept
that this behaviour may break at any time without notice.
It requires Alertmanager >= 0.27.0.
enableServiceLinks defines whether information about services should be injected into pod's environment variables
externalUrl defines the URL used to access the Alertmanager web service. This is
necessary to generate correct URLs. This is necessary if Alertmanager is not
served from root of a DNS name.
forceEnableClusterMode ensures Alertmanager does not deactivate the cluster mode when running with a single replica.
Use case is e.g. spanning an Alertmanager cluster across Kubernetes clusters with a single replica in each.
hostAliases Pods configuration
No Additional ItemsHostAlias holds the mapping between IP and hostnames that will be injected as an entry in the
pod's hosts file.
hostnames defines hostnames for the above IP address.

More info: https://kubernetes.io/docs/tasks/configure-pod-container/user-namespaces/
The feature requires at least Kubernetes 1.28 with the UserNamespacesSupport feature gate enabled.
Starting Kubernetes 1.33, the feature is enabled by default.
image if specified has precedence over baseImage, tag and sha
combinations. Specifying the version is still necessary to ensure the
Prometheus Operator knows what version of Alertmanager is being
configured.
imagePullPolicy for the 'alertmanager', 'init-config-reloader' and 'config-reloader' containers.
See https://kubernetes.io/docs/concepts/containers/images/#image-pull-policy for more details.
imagePullSecrets An optional list of references to secrets in the same namespace
to use for pulling prometheus and alertmanager images from registries
see https://kubernetes.io/docs/tasks/configure-pod-container/pull-image-private-registry/
LocalObjectReference contains enough information to let you locate the
referenced object inside the same namespace.
initContainers allows adding initContainers to the pod definition. Those can be used to e.g.
fetch secrets for injection into the Alertmanager configuration from external sources. Any
errors during the execution of an initContainer will lead to a restart of the Pod. More info: https://kubernetes.io/docs/concepts/workloads/pods/init-containers/
InitContainers described here modify an operator
generated init containers if they share the same name and modifications are
done via a strategic merge patch. The current init container name is:
init-config-reloader. Overriding init containers is entirely outside the
scope of what the maintainers will support and by doing so, you accept that
this behaviour may break at any time without notice.
A single application container that you want to run within a pod.
Arguments to the entrypoint.
The container image's CMD is used if this is not provided.
Variable references $(VARNAME) are expanded using the container's environment. If a variable
cannot be resolved, the reference in the input string will be unchanged. Double $$ are reduced
to a single $, which allows for escaping the $(VARNAME) syntax: i.e. "$$(VARNAME)" will
produce the string literal "$(VARNAME)". Escaped references will never be expanded, regardless
of whether the variable exists or not. Cannot be updated.

any service environment variables. If a variable cannot be resolved,
the reference in the input string will be unchanged. Double $$ are reduced
to a single $, which allows for escaping the $(VARNAME) syntax: i.e.
"$$(VARNAME)" will produce the string literal "$(VARNAME)".

Name must be an IANASVCNAME.
PreStop is called immediately before a container is terminated due to an
API request or management event such as liveness/startup probe failure,
preemption, resource contention, etc. The handler is not called if the
container crashes or exits. The Pod's termination grace period countdown begins before the
PreStop hook is executed. Regardless of the outcome of the handler, the
container will eventually terminate within the Pod's termination grace
period (unless delayed by finalizers). Other management of the container blocks until the hook completes
or until the termination grace period is reached.

RestartPolicy defines the restart behavior of individual containers in a pod.
This overrides the pod-level restart policy. When this field is not specified,
the restart behavior is defined by the Pod's restart policy and the container type.
Additionally, setting the RestartPolicy as "Always" for the init container will
have the following effect:
this init container will be continually restarted on
exit until all regular containers have terminated. Once all regular
containers have completed, all init containers with restartPolicy "Always"
will be shut down. This lifecycle differs from normal init containers and
is often referred to as a "sidecar" container. Although this init
container still starts in the init container sequence, it does not wait
for the container to complete before proceeding to the next init
container. Instead, the next init container starts immediately after this
init container is started, or after any startupProbe has successfully
completed.
Represents a list of rules to be checked to determine if the
container should be restarted on exit. The rules are evaluated in
order. Once a rule matches a container exit condition, the remaining
rules are ignored. If no rule matches the container exit condition,
the Container-level restart policy determines the whether the container
is restarted or not. Constraints on the rules:
- At most 20 rules are allowed.
- Rules can have the same action.
- Identical rules are not forbidden in validations.
When rules are specified, container MUST set RestartPolicy explicitly
even it if matches the Pod's RestartPolicy.
ContainerRestartRule describes how a container exit is handled.
Specifies the action taken on a container exit if the requirements
are satisfied. The only possible value is "Restart" to restart the
container.
Represents the exit codes to check on container exits.
Represents the relationship between the container exit code(s) and the
specified values. Possible values are:
- In: the requirement is satisfied if the container exit code is in the
set of specified values.
- NotIn: the requirement is satisfied if the container exit code is
not in the set of specified values.
Specifies the set of values to check for container exit codes.
At most 255 elements are allowed.

Whether this container should allocate a buffer for stdin in the container runtime. If this
is not set, reads from stdin in the container will always result in EOF.
Default is false.
Whether the container runtime should close the stdin channel after it has been opened by
a single attach. When stdin is true the stdin stream will remain open across multiple attach
sessions. If stdinOnce is set to true, stdin is opened on container start, is empty until the
first client attaches to stdin, and then remains open and accepts data until the client disconnects,
at which time stdin is closed and remains closed until the container is restarted. If this
flag is false, a container processes that reads from stdin will never receive an EOF.
Default is false
Optional: Path at which the file to which the container's termination message
will be written is mounted into the container's filesystem.
Message written is intended to be brief final status, such as an assertion failure message.
Will be truncated by the node if greater than 4096 bytes. The total message length across
all containers will be limited to 12kb.
Defaults to /dev/termination-log.
Cannot be updated.
Indicate how the termination message should be populated. File will use the contents of
terminationMessagePath to populate the container status message on both success and failure.

If ReadOnly is true, and this field is set to Disabled, the mount is not made
recursively read-only. If this field is set to IfPossible, the mount is made
recursively read-only, if it is supported by the container runtime. If this
field is set to Enabled, the mount is made recursively read-only if it is
supported by the container runtime, otherwise the pod will not be started and
an error will be generated to indicate the reason.
If this field is set to IfPossible or Enabled, MountPropagation must be set to
None (or be unspecified, which defaults to None).
If this field is not specified, it is treated as an equivalent of Disabled.
Path within the volume from which the container's volume should be mounted.
Defaults to "" (volume's root).
Expanded path within the volume from which the container's volume should be mounted.
Behaves similarly to SubPath but environment variable references $(VAR_NAME) are expanded using the container's environment.
Defaults to "" (volume's root).
SubPathExpr and SubPath are mutually exclusive.
Container's working directory.
If not specified, the container runtime's default will be used, which
might be configured in the container image.
Cannot be updated.
limits defines the limits command line flags when starting Alertmanager.
maxPerSilenceBytes defines the maximum size of an individual silence as stored on disk. This corresponds to the Alertmanager's
--silences.max-per-silence-bytes flag.
It requires Alertmanager >= v0.28.0.
(^0|([0-9]*[.])?[0-9]+((K|M|G|T|E|P)i?)?B)$
maxSilences defines the maximum number active and pending silences. This corresponds to the
Alertmanager's --silences.max-silences flag.
It requires Alertmanager >= v0.28.0.
Value must be greater or equal to 0
listenLocal defines the Alertmanager server listen on loopback, so that it
does not bind against the Pod IP. Note this is only for the Alertmanager
UI, not the gossip communication.
logFormat for Alertmanager to be configured with.
logLevel for Alertmanager to be configured with.
minReadySeconds defines the minimum number of seconds for which a newly
created pod should be ready without any of its container crashing for it
to be considered available.
If unset, pods will be considered available as soon as they are ready.
When the Alertmanager version is greater than or equal to v0.30.0, the
duration is also used to delay the first flush of the aggregation
groups. This delay helps ensuring that all alerts have been resent by
the Prometheus instances to Alertmanager after a roll-out. It is
possible to override this behavior passing a custom value via
.spec.additionalArgs.
Value must be greater or equal to 0
nodeSelector defines which Nodes the Pods are scheduled on.
Each additional property must conform to the following schema
Type: stringpaused if set to true all actions on the underlying managed objects are not
going to be performed, except for delete actions.
persistentVolumeClaimRetentionPolicy controls if and how PVCs are deleted during the lifecycle of a StatefulSet.
The default behavior is all PVCs are retained.
This is an alpha field from kubernetes 1.23 until 1.26 and a beta field from 1.26.
It requires enabling the StatefulSetAutoDeletePVC feature gate.
WhenDeleted specifies what happens to PVCs created from StatefulSet
VolumeClaimTemplates when the StatefulSet is deleted. The default policy
of Retain causes PVCs to not be affected by StatefulSet deletion. The
Delete policy causes those PVCs to be deleted.
WhenScaled specifies what happens to PVCs created from StatefulSet
VolumeClaimTemplates when the StatefulSet is scaled down. The default
policy of Retain causes PVCs to not be affected by a scaledown. The
Delete policy causes the associated PVCs for any excess pods above
the replica count to be deleted.
podManagementPolicy defines the policy for creating/deleting pods when
scaling up and down.
Unlike the default StatefulSet behavior, the default policy is
Parallel to avoid manual intervention in case a pod gets stuck during
a rollout.
Note that updating this value implies the recreation of the StatefulSet
which incurs a service outage.
podMetadata defines labels and annotations which are propagated to the Alertmanager pods.
The following items are reserved and cannot be overridden:
* "alertmanager" label, set to the name of the Alertmanager instance.
* "app.kubernetes.io/instance" label, set to the name of the Alertmanager instance.
* "app.kubernetes.io/managed-by" label, set to "prometheus-operator".
* "app.kubernetes.io/name" label, set to "alertmanager".
* "app.kubernetes.io/version" label, set to the Alertmanager version.
* "kubectl.kubernetes.io/default-container" annotation, set to "alertmanager".
annotations defines an unstructured key value map stored with a resource that may be
set by external tools to store and retrieve arbitrary metadata. They are not
queryable and should be preserved when modifying objects.
More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/annotations/
Each additional property must conform to the following schema
Type: stringlabels define the map of string keys and values that can be used to organize and categorize
(scope and select) objects. May match selectors of replication controllers
and services.
More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/
Each additional property must conform to the following schema
Type: stringname must be unique within a namespace. Is required when creating resources, although
some resources may allow a client to request the generation of an appropriate name
automatically. Name is primarily intended for creation idempotence and configuration
definition.
Cannot be updated.
More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names/
portName defines the port's name for the pods and governing service.
Defaults to web.
priorityClassName assigned to the Pods
replicas defines the expected size of the alertmanager cluster. The controller will
eventually make the size of the running cluster equal to the expected
size.
resources defines the resource requests and limits of the Pods.
Claims lists the names of resources, defined in spec.resourceClaims,
that are used by this container.
This field depends on the
DynamicResourceAllocation feature gate.
This field is immutable. It can only be set for containers.
ResourceClaim references one entry in PodSpec.ResourceClaims.
Name must match the name of one entry in pod.spec.resourceClaims of
the Pod where this field is used. It makes that resource available
inside a container.
Request is the name chosen for a request in the referenced claim.
If empty, everything from the claim is made available, otherwise
only the result of this request.
Limits describes the maximum amount of compute resources allowed.
More info: https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/
Each additional property must conform to the following schema
Type: object^(\+|-)?(([0-9]+(\.[0-9]*)?)|(\.[0-9]+))(([KMGTPE]i)|[numkMGTPE]|([eE](\+|-)?(([0-9]+(\.[0-9]*)?)|(\.[0-9]+))))?$
Requests describes the minimum amount of compute resources required.
If Requests is omitted for a container, it defaults to Limits if that is explicitly specified,
otherwise to an implementation-defined value. Requests cannot exceed Limits.
More info: https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/
Each additional property must conform to the following schema
Type: object^(\+|-)?(([0-9]+(\.[0-9]*)?)|(\.[0-9]+))(([KMGTPE]i)|[numkMGTPE]|([eE](\+|-)?(([0-9]+(\.[0-9]*)?)|(\.[0-9]+))))?$
retention defines the time duration Alertmanager shall retain data for. Default is '120h',
and must match the regular expression [0-9]+(ms|s|m|h) (milliseconds seconds minutes hours).
^(0|(([0-9]+)h)?(([0-9]+)m)?(([0-9]+)s)?(([0-9]+)ms)?)$
secrets is a list of Secrets in the same namespace as the Alertmanager
object, which shall be mounted into the Alertmanager Pods.
Each Secret is added to the StatefulSet definition as a volume named secret-<secret-name>.
The Secrets are mounted into /etc/alertmanager/secrets/<secret-name> in the 'alertmanager' container.
securityContext holds pod-level security attributes and common container settings.
This defaults to the default PodSecurityContext.
appArmorProfile is the AppArmor options to use by the containers in this pod.
Note that this field cannot be set when spec.os.name is windows.
localhostProfile indicates a profile loaded on the node that should be used.
The profile must be preconfigured on the node to work.
Must match the loaded name of the profile.
Must be set if and only if type is "Localhost".
A special supplemental group that applies to all containers in a pod.
Some volume types allow the Kubelet to change the ownership of that volume
to be owned by the pod:
If unset, the Kubelet will not modify the ownership and permissions of any volume.
Note that this field cannot be set when spec.os.name is windows.
fsGroupChangePolicy defines behavior of changing ownership and permission of the volume
before being exposed inside Pod. This field will only apply to
volume types which support fsGroup based ownership(and permissions).
It will have no effect on ephemeral volume types such as: secret, configmaps
and emptydir.
Valid values are "OnRootMismatch" and "Always". If not specified, "Always" is used.
Note that this field cannot be set when spec.os.name is windows.
The GID to run the entrypoint of the container process.
Uses runtime default if unset.
May also be set in SecurityContext. If set in both SecurityContext and
PodSecurityContext, the value specified in SecurityContext takes precedence
for that container.
Note that this field cannot be set when spec.os.name is windows.
Indicates that the container must run as a non-root user.
If true, the Kubelet will validate the image at runtime to ensure that it
does not run as UID 0 (root) and fail to start the container if it does.
If unset or false, no such validation will be performed.
May also be set in SecurityContext. If set in both SecurityContext and
PodSecurityContext, the value specified in SecurityContext takes precedence.
The UID to run the entrypoint of the container process.
Defaults to user specified in image metadata if unspecified.
May also be set in SecurityContext. If set in both SecurityContext and
PodSecurityContext, the value specified in SecurityContext takes precedence
for that container.
Note that this field cannot be set when spec.os.name is windows.
seLinuxChangePolicy defines how the container's SELinux label is applied to all volumes used by the Pod.
It has no effect on nodes that do not support SELinux or to volumes does not support SELinux.
Valid values are "MountOption" and "Recursive".
"Recursive" means relabeling of all files on all Pod volumes by the container runtime.
This may be slow for large volumes, but allows mixing privileged and unprivileged Pods sharing the same volume on the same node.
"MountOption" mounts all eligible Pod volumes with -o context mount option.
This requires all Pods that share the same volume to use the same SELinux label.
It is not possible to share the same volume among privileged and unprivileged Pods.
Eligible volumes are in-tree FibreChannel and iSCSI volumes, and all CSI volumes
whose CSI driver announces SELinux support by setting spec.seLinuxMount: true in their
CSIDriver instance. Other volumes are always re-labelled recursively.
"MountOption" value is allowed only when SELinuxMount feature gate is enabled.
If not specified and SELinuxMount feature gate is enabled, "MountOption" is used.
If not specified and SELinuxMount feature gate is disabled, "MountOption" is used for ReadWriteOncePod volumes
and "Recursive" for all other volumes.
This field affects only Pods that have SELinux label set, either in PodSecurityContext or in SecurityContext of all containers.
All Pods that use the same volume should use the same seLinuxChangePolicy, otherwise some pods can get stuck in ContainerCreating state.
Note that this field cannot be set when spec.os.name is windows.
The SELinux context to be applied to all containers.
If unspecified, the container runtime will allocate a random SELinux context for each
container. May also be set in SecurityContext. If set in
both SecurityContext and PodSecurityContext, the value specified in SecurityContext
takes precedence for that container.
Note that this field cannot be set when spec.os.name is windows.
Level is SELinux level label that applies to the container.
Role is a SELinux role label that applies to the container.
Type is a SELinux type label that applies to the container.
User is a SELinux user label that applies to the container.
The seccomp options to use by the containers in this pod.
Note that this field cannot be set when spec.os.name is windows.
localhostProfile indicates a profile defined in a file on the node should be used.
The profile must be preconfigured on the node to work.
Must be a descending path, relative to the kubelet's configured seccomp profile location.
Must be set if type is "Localhost". Must NOT be set for any other type.
A list of groups applied to the first process run in each container, in
addition to the container's primary GID and fsGroup (if specified). If
the SupplementalGroupsPolicy feature is enabled, the
supplementalGroupsPolicy field determines whether these are in addition
to or instead of any group memberships defined in the container image.
If unspecified, no additional groups are added, though group memberships
defined in the container image may still be used, depending on the
supplementalGroupsPolicy field.
Note that this field cannot be set when spec.os.name is windows.
Defines how supplemental groups of the first container processes are calculated.
Valid values are "Merge" and "Strict". If not specified, "Merge" is used.
(Alpha) Using the field requires the SupplementalGroupsPolicy feature gate to be enabled
and the container runtime must implement support for this feature.
Note that this field cannot be set when spec.os.name is windows.
Sysctls hold a list of namespaced sysctls used for the pod. Pods with unsupported
sysctls (by the container runtime) might fail to launch.
Note that this field cannot be set when spec.os.name is windows.
Sysctl defines a kernel parameter to be set
Name of a property to set
Value of a property to set
The Windows specific settings applied to all containers.
If unspecified, the options within a container's SecurityContext will be used.
If set in both SecurityContext and PodSecurityContext, the value specified in SecurityContext takes precedence.
Note that this field cannot be set when spec.os.name is linux.
GMSACredentialSpec is where the GMSA admission webhook
(https://github.com/kubernetes-sigs/windows-gmsa) inlines the contents of the
GMSA credential spec named by the GMSACredentialSpecName field.
GMSACredentialSpecName is the name of the GMSA credential spec to use.
HostProcess determines if a container should be run as a 'Host Process' container.
All of a Pod's containers must have the same effective HostProcess value
(it is not allowed to have a mix of HostProcess containers and non-HostProcess containers).
In addition, if HostProcess is true then HostNetwork must also be set to true.
The UserName in Windows to run the entrypoint of the container process.
Defaults to the user specified in image metadata if unspecified.
May also be set in PodSecurityContext. If set in both SecurityContext and
PodSecurityContext, the value specified in SecurityContext takes precedence.
serviceAccountName is the name of the ServiceAccount to use to run the
Prometheus Pods.
serviceName defines the service name used by the underlying StatefulSet(s) as the governing service.
If defined, the Service must be created before the Alertmanager resource in the same namespace and it must define a selector that matches the pod labels.
If empty, the operator will create and manage a headless service named alertmanager-operated for Alertmanager resources.
When deploying multiple Alertmanager resources in the same namespace, it is recommended to specify a different value for each.
See https://kubernetes.io/docs/concepts/workloads/controllers/statefulset/#stable-network-id for more details.
Must be at least 1 characters long
sha of Alertmanager container image to be deployed. Defaults to the value of version.
Similar to a tag, but the SHA explicitly deploys an immutable container image.
Version and Tag are ignored if SHA is set.
Deprecated: use 'image' instead. The image digest can be specified as part of the image URL.
storage defines the definition of how storage will be used by the Alertmanager
instances.
disableMountSubPath deprecated: subPath usage will be removed in a future release.
emptyDir to be used by the StatefulSet.
If specified, it takes precedence over ephemeral and volumeClaimTemplate.
More info: https://kubernetes.io/docs/concepts/storage/volumes/#emptydir
medium represents what type of storage medium should back this directory.
The default is "" which means to use the node's default medium.
Must be an empty string (default) or Memory.
More info: https://kubernetes.io/docs/concepts/storage/volumes#emptydir
sizeLimit is the total amount of local storage required for this EmptyDir volume.
The size limit is also applicable for memory medium.
The maximum usage on memory medium EmptyDir would be the minimum value between
the SizeLimit specified here and the sum of memory limits of all containers in a pod.
The default is nil which means that the limit is undefined.

ephemeral to be used by the StatefulSet.
This is a beta field in k8s 1.21 and GA in 1.15.
For lower versions, starting with k8s 1.19, it requires enabling the GenericEphemeralVolume feature gate.
More info: https://kubernetes.io/docs/concepts/storage/ephemeral-volumes/#generic-ephemeral-volumes
Will be used to create a stand-alone PVC to provision the volume.
The pod in which this EphemeralVolumeSource is embedded will be the
owner of the PVC, i.e. the PVC will be deleted together with the
pod. The name of the PVC will be <pod name>-<volume name> where
<volume name> is the name from the PodSpec.Volumes array
entry. Pod validation will reject the pod if the concatenated name
is not valid for a PVC (for example, too long).
An existing PVC with that name that is not owned by the pod
will not be used for the pod to avoid using an unrelated
volume by mistake. Starting the pod is then blocked until
the unrelated PVC is removed. If such a pre-created PVC is
meant to be used by the pod, the PVC has to updated with an
owner reference to the pod once the pod exists. Normally
this should not be necessary, but it may be useful when
manually reconstructing a broken cluster.
This field is read-only and no changes will be made by Kubernetes
to the PVC after it has been created.
Required, must not be nil.
May contain labels and annotations that will be copied into the PVC
when creating it. No other fields are allowed and will be rejected during
validation.
The specification for the PersistentVolumeClaim. The entire content is
copied unchanged into the PVC that gets created from this
template. The same fields as in a PersistentVolumeClaim
are also valid here.
accessModes contains the desired access modes the volume should have.
More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#access-modes-1
dataSource field can be used to specify either:
* An existing VolumeSnapshot object (snapshot.storage.k8s.io/VolumeSnapshot)
* An existing PVC (PersistentVolumeClaim)
If the provisioner or an external controller can support the specified data source,
it will create a new volume based on the contents of the specified data source.
When the AnyVolumeDataSource feature gate is enabled, dataSource contents will be copied to dataSourceRef,
and dataSourceRef contents will be copied to dataSource when dataSourceRef.namespace is not specified.
If the namespace is specified, then dataSourceRef will not be copied to dataSource.
APIGroup is the group for the resource being referenced.
If APIGroup is not specified, the specified Kind must be in the core API group.
For any other third-party types, APIGroup is required.
Kind is the type of resource being referenced
Name is the name of resource being referenced
dataSourceRef specifies the object from which to populate the volume with data, if a non-empty
volume is desired. This may be any object from a non-empty API group (non
core object) or a PersistentVolumeClaim object.
When this field is specified, volume binding will only succeed if the type of
the specified object matches some installed volume populator or dynamic
provisioner.
This field will replace the functionality of the dataSource field and as such
if both fields are non-empty, they must have the same value. For backwards
compatibility, when namespace isn't specified in dataSourceRef,
both fields (dataSource and dataSourceRef) will be set to the same
value automatically if one of them is empty and the other is non-empty.
When namespace is specified in dataSourceRef,
dataSource isn't set to the same value and must be empty.
There are three important differences between dataSource and dataSourceRef:
* While dataSource only allows two specific types of objects, dataSourceRef
allows any non-core object, as well as PersistentVolumeClaim objects.
* While dataSource ignores disallowed values (dropping them), dataSourceRef
preserves all values, and generates an error if a disallowed value is
specified.
* While dataSource only allows local objects, dataSourceRef allows objects
in any namespaces.
(Beta) Using this field requires the AnyVolumeDataSource feature gate to be enabled.

If specified, the CSI driver will create or update the volume with the attributes defined
in the corresponding VolumeAttributesClass. This has a different purpose than storageClassName,
it can be changed after the claim is created. An empty string or nil value indicates that no
VolumeAttributesClass will be applied to the claim. If the claim enters an Infeasible error state,
this field can be reset to its previous value (including nil) to cancel the modification.
If the resource referred to by volumeAttributesClass does not exist, this PersistentVolumeClaim will be

map is equivalent to an element of matchExpressions, whose key field is "key", the
operator is "In", and the values array contains only "value". The requirements are ANDed.
Each additional property must conform to the following schema
Type: stringstorageClassName is the name of the StorageClass required by the claim.
More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#class-1
volumeAttributesClassName may be used to set the VolumeAttributesClass used by this claim.
If specified, the CSI driver will create or update the volume with the attributes defined
in the corresponding VolumeAttributesClass. This has a different purpose than storageClassName,
it can be changed after the claim is created. An empty string or nil value indicates that no
VolumeAttributesClass will be applied to the claim. If the claim enters an Infeasible error state,
this field can be reset to its previous value (including nil) to cancel the modification.
If the resource referred to by volumeAttributesClass does not exist, this PersistentVolumeClaim will be
set to a Pending state, as reflected by the modifyVolumeStatus field, until such as a resource
exists.
More info: https://kubernetes.io/docs/concepts/storage/volume-attributes-classes/
volumeMode defines what type of volume is required by the claim.
Value of Filesystem is implied when not included in claim spec.
volumeName is the binding reference to the PersistentVolume backing this claim.
status is deprecated: this field is never set.
accessModes contains the actual access modes the volume backing the PVC has.
More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#access-modes-1
allocatedResourceStatuses stores status of resource being resized for the given PVC.
Key names follow standard Kubernetes label syntax. Valid values are either:
* Un-prefixed keys:
- storage - the capacity of the volume.
* Custom resources must use implementation-defined prefixed names such as "example.com/my-custom-resource"
Apart from above values - keys that are unprefixed or have kubernetes.io prefix are considered
reserved and hence may not be used.
ClaimResourceStatus can be in any of following states:
- ControllerResizeInProgress:
State set when resize controller starts resizing the volume in control-plane.
- ControllerResizeFailed:
State set when resize has failed in resize controller with a terminal error.
- NodeResizePending:
State set when resize controller has finished resizing the volume but further resizing of
volume is needed on the node.
- NodeResizeInProgress:
State set when kubelet starts resizing the volume.
- NodeResizeFailed:
State set when resizing has failed in kubelet with a terminal error. Transient errors don't set
NodeResizeFailed.
For example: if expanding a PVC for more capacity - this field can be one of the following states:
- pvc.status.allocatedResourceStatus['storage'] = "ControllerResizeInProgress"
- pvc.status.allocatedResourceStatus['storage'] = "ControllerResizeFailed"
- pvc.status.allocatedResourceStatus['storage'] = "NodeResizePending"
- pvc.status.allocatedResourceStatus['storage'] = "NodeResizeInProgress"
- pvc.status.allocatedResourceStatus['storage'] = "NodeResizeFailed"
When this field is not set, it means that no resize operation is in progress for the given PVC.
A controller that receives PVC update with previously unknown resourceName or ClaimResourceStatus
should ignore the update for the purpose it was designed. For example - a controller that
only is responsible for resizing capacity of the volume, should ignore PVC updates that change other valid
resources associated with PVC.
This is an alpha field and requires enabling RecoverVolumeExpansionFailure feature.
Each additional property must conform to the following schema
Type: stringWhen a controller receives persistentvolume claim update with ClaimResourceStatus for a resource
that it does not recognizes, then it should ignore that update and let other controllers
handle it.
allocatedResources tracks the resources allocated to a PVC including its capacity.
Key names follow standard Kubernetes label syntax. Valid values are either:
* Un-prefixed keys:
- storage - the capacity of the volume.
* Custom resources must use implementation-defined prefixed names such as "example.com/my-custom-resource"
Apart from above values - keys that are unprefixed or have kubernetes.io prefix are considered
reserved and hence may not be used.
Capacity reported here may be larger than the actual capacity when a volume expansion operation
is requested.
For storage quota, the larger value from allocatedResources and PVC.spec.resources is used.
If allocatedResources is not set, PVC.spec.resources alone is used for quota calculation.
If a volume expansion capacity request is lowered, allocatedResources is only
lowered if there are no expansion operations in progress and if the actual volume capacity
is equal or lower than the requested capacity.
A controller that receives PVC update with previously unknown resourceName
should ignore the update for the purpose it was designed. For example - a controller that
only is responsible for resizing capacity of the volume, should ignore PVC updates that change other valid
resources associated with PVC.

currentVolumeAttributesClassName is the current name of the VolumeAttributesClass the PVC is using.
When unset, there is no VolumeAttributeClass applied to this PersistentVolumeClaim
ModifyVolumeStatus represents the status object of ControllerModifyVolume operation.
When this is unset, there is no ModifyVolume operation being attempted.
status is the status of the ControllerModifyVolume operation. It can be in any of following states:
- Pending
Pending indicates that the PersistentVolumeClaim cannot be modified due to unmet requirements, such as
the specified VolumeAttributesClass not existing.
- InProgress
InProgress indicates that the volume is being modified.
- Infeasible
Infeasible indicates that the request has been rejected as invalid by the CSI driver. To
resolve the error, a valid VolumeAttributesClass needs to be specified.
Note: New statuses can be added in the future. Consumers should check for unknown statuses and fail appropriately.
targetVolumeAttributesClassName is the name of the VolumeAttributesClass the PVC currently being reconciled
phase represents the current phase of PersistentVolumeClaim.
tag of Alertmanager container image to be deployed. Defaults to the value of version.
Version is ignored if Tag is set.
Deprecated: use 'image' instead. The image tag can be specified as part of the image URL.
terminationGracePeriodSeconds defines the Optional duration in seconds the pod needs to terminate gracefully.
Value must be non-negative integer. The value zero indicates stop immediately via
the kill signal (no opportunity to shut down) which may lead to data corruption.
Defaults to 120 seconds.
Value must be greater or equal to 0
tolerations defines the pod's tolerations.
No Additional ItemsThe pod this Toleration is attached to tolerates any taint that matches
the triple <key,value,effect> using the matching operator <operator>.
Effect indicates the taint effect to match. Empty means match all taint effects.
When specified, allowed values are NoSchedule, PreferNoSchedule and NoExecute.
Key is the taint key that the toleration applies to. Empty means match all taint keys.
If the key is empty, operator must be Exists; this combination means to match all values and all keys.
Operator represents a key's relationship to the value.
Valid operators are Exists and Equal. Defaults to Equal.
Exists is equivalent to wildcard for value, so that a pod can
tolerate all taints of a particular category.
TolerationSeconds represents the period of time the toleration (which must be
of effect NoExecute, otherwise this field is ignored) tolerates the taint. By default,
it is not set, which means tolerate the taint forever (do not evict). Zero and
negative values will be treated as 0 (evict immediately) by the system.
Value is the taint value the toleration matches to.
If the operator is Exists, the value should be empty, otherwise just a regular string.
topologySpreadConstraints defines the Pod's topology spread constraints.
No Additional ItemsTopologySpreadConstraint specifies how to spread matching pods among the given topology.
LabelSelector is used to find matching pods.
Pods that match this label selector are counted to determine the number of pods
in their corresponding topology domain.
matchExpressions is a list of label selector requirements. The requirements are ANDed.
No Additional ItemsA label selector requirement is a selector that contains values, a key, and an operator that
relates the key and values.
key is the label key that the selector applies to.
operator represents a key's relationship to a set of values.
Valid operators are In, NotIn, Exists and DoesNotExist.
values is an array of string values. If the operator is In or NotIn,
the values array must be non-empty. If the operator is Exists or DoesNotExist,
the values array must be empty. This array is replaced during a strategic
merge patch.
matchLabels is a map of {key,value} pairs. A single {key,value} in the matchLabels
map is equivalent to an element of matchExpressions, whose key field is "key", the
operator is "In", and the values array contains only "value". The requirements are ANDed.
Each additional property must conform to the following schema
Type: stringMatchLabelKeys is a set of pod label keys to select the pods over which
spreading will be calculated. The keys are used to lookup values from the
incoming pod labels, those key-value labels are ANDed with labelSelector
to select the group of existing pods over which spreading will be calculated
for the incoming pod. The same key is forbidden to exist in both MatchLabelKeys and LabelSelector.
MatchLabelKeys cannot be set when LabelSelector isn't set.
Keys that don't exist in the incoming pod labels will
be ignored. A null or empty list means only match against labelSelector.
This is a beta field and requires the MatchLabelKeysInPodTopologySpread feature gate to be enabled (enabled by default).
MaxSkew describes the degree to which pods may be unevenly distributed.
When whenUnsatisfiable=DoNotSchedule, it is the maximum permitted difference
between the number of matching pods in the target topology and the global minimum.
The global minimum is the minimum number of matching pods in an eligible domain
or zero if the number of eligible domains is less than MinDomains.
For example, in a 3-zone cluster, MaxSkew is set to 1, and pods with the same
labelSelector spread as 2/2/1:
In this case, the global minimum is 1.
| zone1 | zone2 | zone3 |
| P P | P P | P |
- if MaxSkew is 1, incoming pod can only be scheduled to zone3 to become 2/2/2;
scheduling it onto zone1(zone2) would make the ActualSkew(3-1) on zone1(zone2)
violate MaxSkew(1).
- if MaxSkew is 2, incoming pod can be scheduled onto any zone.
When whenUnsatisfiable=ScheduleAnyway, it is used to give higher precedence
to topologies that satisfy it.
It's a required field. Default value is 1 and 0 is not allowed.
MinDomains indicates a minimum number of eligible domains.
When the number of eligible domains with matching topology keys is less than minDomains,
Pod Topology Spread treats "global minimum" as 0, and then the calculation of Skew is performed.
And when the number of eligible domains with matching topology keys equals or greater than minDomains,
this value has no effect on scheduling.
As a result, when the number of eligible domains is less than minDomains,
scheduler won't schedule more than maxSkew Pods to those domains.
If value is nil, the constraint behaves as if MinDomains is equal to 1.
Valid values are integers greater than 0.
When value is not nil, WhenUnsatisfiable must be DoNotSchedule.
For example, in a 3-zone cluster, MaxSkew is set to 2, MinDomains is set to 5 and pods with the same
labelSelector spread as 2/2/2:
| zone1 | zone2 | zone3 |
| P P | P P | P P |
The number of domains is less than 5(MinDomains), so "global minimum" is treated as 0.
In this situation, new pod with the same labelSelector cannot be scheduled,
because computed skew will be 3(3 - 0) if new Pod is scheduled to any of the three zones,
it will violate MaxSkew.
NodeAffinityPolicy indicates how we will treat Pod's nodeAffinity/nodeSelector
when calculating pod topology spread skew. Options are:
- Honor: only nodes matching nodeAffinity/nodeSelector are included in the calculations.
- Ignore: nodeAffinity/nodeSelector are ignored. All nodes are included in the calculations.
If this value is nil, the behavior is equivalent to the Honor policy.
NodeTaintsPolicy indicates how we will treat node taints when calculating
pod topology spread skew. Options are:
- Honor: nodes without taints, along with tainted nodes for which the incoming pod
has a toleration, are included.
- Ignore: node taints are ignored. All nodes are included.
If this value is nil, the behavior is equivalent to the Ignore policy.
TopologyKey is the key of node labels. Nodes that have a label with this key
and identical values are considered to be in the same topology.
We consider each <key, value> as a "bucket", and try to put balanced number
of pods into each bucket.
We define a domain as a particular instance of a topology.
Also, we define an eligible domain as a domain whose nodes meet the requirements of
nodeAffinityPolicy and nodeTaintsPolicy.
e.g. If TopologyKey is "kubernetes.io/hostname", each Node is a domain of that topology.
And, if TopologyKey is "topology.kubernetes.io/zone", each zone is a domain of that topology.
It's a required field.
WhenUnsatisfiable indicates how to deal with a pod if it doesn't satisfy
the spread constraint.
- DoNotSchedule (default) tells the scheduler not to schedule it.
- ScheduleAnyway tells the scheduler to schedule the pod in any location,
but giving higher precedence to topologies that would help reduce the
skew.
A constraint is considered "Unsatisfiable" for an incoming pod
if and only if every possible node assignment for that pod would violate
"MaxSkew" on some topology.
For example, in a 3-zone cluster, MaxSkew is set to 1, and pods with the same
labelSelector spread as 3/1/1:
| zone1 | zone2 | zone3 |
| P P P | P | P |
If WhenUnsatisfiable is set to DoNotSchedule, incoming pod can only be scheduled
to zone2(zone3) to become 3/2/1(3/1/2) as ActualSkew(2-1) on zone2(zone3) satisfies
MaxSkew(1). In other words, the cluster can still be imbalanced, but scheduler
won't make it more imbalanced.
It's a required field.
updateStrategy indicates the strategy that will be employed to update
Pods in the StatefulSet when a revision is made to statefulset's Pod
Template.
The default strategy is RollingUpdate.
rollingUpdate is used to communicate parameters when type is RollingUpdate.
type indicates the type of the StatefulSetUpdateStrategy.
Default is RollingUpdate.
version the cluster should be on.
volumeMounts allows configuration of additional VolumeMounts on the output StatefulSet definition.
VolumeMounts specified will be appended to other VolumeMounts in the alertmanager container,
that are generated as a result of StorageSpec objects.
VolumeMount describes a mounting of a Volume within a container.
Path within the container at which the volume should be mounted. Must
not contain ':'.
mountPropagation determines how mounts are propagated from the host
to container and the other way around.
When not set, MountPropagationNone is used.
This field is beta in 1.10.
When RecursiveReadOnly is set to IfPossible or to Enabled, MountPropagation must be None or unspecified
(which defaults to None).
This must match the Name of a Volume.
Mounted read-only if true, read-write otherwise (false or unspecified).
Defaults to false.
RecursiveReadOnly specifies whether read-only mounts should be handled
recursively.
If ReadOnly is false, this field has no meaning and must be unspecified.
If ReadOnly is true, and this field is set to Disabled, the mount is not made
recursively read-only. If this field is set to IfPossible, the mount is made
recursively read-only, if it is supported by the container runtime. If this
field is set to Enabled, the mount is made recursively read-only if it is
supported by the container runtime, otherwise the pod will not be started and
an error will be generated to indicate the reason.
If this field is set to IfPossible or Enabled, MountPropagation must be set to
None (or be unspecified, which defaults to None).
If this field is not specified, it is treated as an equivalent of Disabled.
Path within the volume from which the container's volume should be mounted.
Defaults to "" (volume's root).
Expanded path within the volume from which the container's volume should be mounted.
Behaves similarly to SubPath but environment variable references $(VAR_NAME) are expanded using the container's environment.
Defaults to "" (volume's root).
SubPathExpr and SubPath are mutually exclusive.

Volumes specified will be appended to other volumes that are generated as a result of
StorageSpec objects.

ephemeral represents a volume that is handled by a cluster storage driver.
The volume's lifecycle is tied to the pod that defines it - it will be created before the pod starts,
and deleted when the pod is removed.
Use this if:
a) the volume is only needed while the pod runs,
b) features of normal volumes like restoring from snapshot or capacity
tracking are needed,
c) the storage driver is specified through a storage class, and
d) the storage driver supports dynamic volume provisioning through
a PersistentVolumeClaim (see EphemeralVolumeSource for more
information on the connection between this volume type
and PersistentVolumeClaim).
Use PersistentVolumeClaim or one of the vendor-specific
APIs for volumes that persist for longer than the lifecycle
of an individual pod.
Use CSI for light-weight local ephemeral volumes if the CSI driver is meant to
be used that way - see the documentation of the driver for
more information.
A pod can use both types of ephemeral volumes and
persistent volumes at the same time.
Will be used to create a stand-alone PVC to provision the volume.
The pod in which this EphemeralVolumeSource is embedded will be the
owner of the PVC, i.e. the PVC will be deleted together with the
pod. The name of the PVC will be <pod name>-<volume name> where
<volume name> is the name from the PodSpec.Volumes array
entry. Pod validation will reject the pod if the concatenated name
is not valid for a PVC (for example, too long).
An existing PVC with that name that is not owned by the pod
will not be used for the pod to avoid using an unrelated
volume by mistake. Starting the pod is then blocked until
the unrelated PVC is removed. If such a pre-created PVC is
meant to be used by the pod, the PVC has to updated with an
owner reference to the pod once the pod exists. Normally
this should not be necessary, but it may be useful when
manually reconstructing a broken cluster.
This field is read-only and no changes will be made by Kubernetes
to the PVC after it has been created.
Required, must not be nil.
May contain labels and annotations that will be copied into the PVC
when creating it. No other fields are allowed and will be rejected during
validation.
The specification for the PersistentVolumeClaim. The entire content is
copied unchanged into the PVC that gets created from this
template. The same fields as in a PersistentVolumeClaim
are also valid here.
accessModes contains the desired access modes the volume should have.

dataSource field can be used to specify either:
* An existing VolumeSnapshot object (snapshot.storage.k8s.io/VolumeSnapshot)
* An existing PVC (PersistentVolumeClaim)
If the provisioner or an external controller can support the specified data source,
it will create a new volume based on the contents of the specified data source.
When the AnyVolumeDataSource feature gate is enabled, dataSource contents will be copied to dataSourceRef,
and dataSourceRef contents will be copied to dataSource when dataSourceRef.namespace is not specified.
If the namespace is specified, then dataSourceRef will not be copied to dataSource.
APIGroup is the group for the resource being referenced.
If APIGroup is not specified, the specified Kind must be in the core API group.
For any other third-party types, APIGroup is required.
Kind is the type of resource being referenced
Name is the name of resource being referenced
dataSourceRef specifies the object from which to populate the volume with data, if a non-empty
volume is desired. This may be any object from a non-empty API group (non
core object) or a PersistentVolumeClaim object.
When this field is specified, volume binding will only succeed if the type of
the specified object matches some installed volume populator or dynamic
provisioner.
This field will replace the functionality of the dataSource field and as such
if both fields are non-empty, they must have the same value. For backwards
compatibility, when namespace isn't specified in dataSourceRef,
both fields (dataSource and dataSourceRef) will be set to the same
value automatically if one of them is empty and the other is non-empty.
When namespace is specified in dataSourceRef,
dataSource isn't set to the same value and must be empty.
There are three important differences between dataSource and dataSourceRef:
* While dataSource only allows two specific types of objects, dataSourceRef
allows any non-core object, as well as PersistentVolumeClaim objects.
* While dataSource ignores disallowed values (dropping them), dataSourceRef
preserves all values, and generates an error if a disallowed value is
specified.
* While dataSource only allows local objects, dataSourceRef allows objects
in any namespaces.
(Beta) Using this field requires the AnyVolumeDataSource feature gate to be enabled.
(Alpha) Using the namespace field of dataSourceRef requires the CrossNamespaceVolumeDataSource feature gate to be enabled.
APIGroup is the group for the resource being referenced.
If APIGroup is not specified, the specified Kind must be in the core API group.
For any other third-party types, APIGroup is required.
Kind is the type of resource being referenced
Name is the name of resource being referenced
Namespace is the namespace of resource being referenced
Note that when a namespace is specified, a gateway.networking.k8s.io/ReferenceGrant object is required in the referent namespace to allow that namespace's owner to accept the reference. See the ReferenceGrant documentation for details.
(Alpha) This field requires the CrossNamespaceVolumeDataSource feature gate to be enabled.
resources represents the minimum resources the volume should have.

If specified, the CSI driver will create or update the volume with the attributes defined
in the corresponding VolumeAttributesClass. This has a different purpose than storageClassName,
it can be changed after the claim is created. An empty string or nil value indicates that no
VolumeAttributesClass will be applied to the claim. If the claim enters an Infeasible error state,
this field can be reset to its previous value (including nil) to cancel the modification.
If the resource referred to by volumeAttributesClass does not exist, this PersistentVolumeClaim will be

image represents an OCI object (a container image or artifact) pulled and mounted on the kubelet's host machine.
The volume is resolved at pod startup depending on which PullPolicy value is provided:
The volume gets re-resolved if the pod gets deleted and recreated, which means that new remote content will become available on pod recreation.
A failure to resolve or pull the image during pod startup will block containers from starting and may add significant latency. Failures will be retried using normal volume backoff and will be reported on the pod reason and message.
The types of objects that may be mounted by this volume are defined by the container runtime implementation on a host machine and at minimum must include all valid types supported by the container image field.
The OCI object gets mounted in a single directory (spec.containers[].volumeMounts.mountPath) by merging the manifest layers in the same way as for container images.
The volume will be mounted read-only (ro) and non-executable files (noexec).
Sub path mounts for containers are not supported (spec.containers[].volumeMounts.subpath) before 1.33.
The field spec.securityContext.fsGroupChangePolicy has no effect on this volume type.
Policy for pulling OCI objects. Possible values are:
Always: the kubelet always attempts to pull the reference. Container creation will fail If the pull fails.
Never: the kubelet never pulls the reference and only uses a local image or artifact. Container creation will fail if the reference isn't present.
IfNotPresent: the kubelet pulls if the reference isn't already present on disk. Container creation will fail if the reference isn't present and the pull fails.
Defaults to Always if :latest tag is specified, or IfNotPresent otherwise.
Required: Image or artifact reference to be used.
Behaves in the same way as pod.spec.containers[*].image.
Pull secrets will be assembled in the same way as for the container image by looking up node credentials, SA image pull secrets, and pod spec image pull secrets.

Projects an auto-rotating credential bundle (private key and certificate
chain) that the pod can use either as a TLS client or server.
Kubelet generates a private key and uses it to send a
PodCertificateRequest to the named signer. Once the signer approves the
request and issues a certificate chain, Kubelet writes the key and
certificate chain to the pod filesystem. The pod does not start until
certificates have been issued for each podCertificate projected volume
source in its spec.
Kubelet will begin trying to rotate the certificate at the time indicated
by the signer using the PodCertificateRequest.Status.BeginRefreshAt
timestamp.
Kubelet can write a single file, indicated by the credentialBundlePath
field, or separate files, indicated by the keyPath and
certificateChainPath fields.
The credential bundle is a single file in PEM format. The first PEM
entry is the private key (in PKCS#8 format), and the remaining PEM
entries are the certificate chain issued by the signer (typically,
signers will return their certificate chain in leaf-to-root order).
Prefer using the credential bundle format, since your application code
can read it atomically. If you use keyPath and certificateChainPath,
your application must make two separate file reads. If these coincide
with a certificate rotation, it is possible that the private key and leaf
certificate you read may not correspond to each other. Your application
will need to check for this condition, and re-read until they are
consistent.
The named signer controls chooses the format of the certificate it
issues; consult the signer implementation's documentation to learn how to
use the certificates it issues.
Write the certificate chain at this path in the projected volume.
Most applications should use credentialBundlePath. When using keyPath
and certificateChainPath, your application needs to check that the key
and leaf certificate are consistent, because it is possible to read the
files mid-rotation.
Write the credential bundle at this path in the projected volume.
The credential bundle is a single file that contains multiple PEM blocks.
The first PEM block is a PRIVATE KEY block, containing a PKCS#8 private
key.
The remaining blocks are CERTIFICATE blocks, containing the issued
certificate chain from the signer (leaf and any intermediates).
Using credentialBundlePath lets your Pod's application code make a single
atomic read that retrieves a consistent key and certificate chain. If you
project them to separate files, your application code will need to
additionally check that the leaf certificate was issued to the key.
The type of keypair Kubelet will generate for the pod.
Valid values are "RSA3072", "RSA4096", "ECDSAP256", "ECDSAP384",
"ECDSAP521", and "ED25519".
maxExpirationSeconds is the maximum lifetime permitted for the
certificate.
Kubelet copies this value verbatim into the PodCertificateRequests it
generates for this projection.
If omitted, kube-apiserver will set it to 86400(24 hours). kube-apiserver
will reject values shorter than 3600 (1 hour). The maximum allowable
value is 7862400 (91 days).
The signer implementation is then free to issue a certificate with any
lifetime shorter than MaxExpirationSeconds, but no shorter than 3600
seconds (1 hour). This constraint is enforced by kube-apiserver.
kubernetes.io signers will never issue certificates with a lifetime
longer than 24 hours.
Kubelet's generated CSRs will be addressed to this signer.
secret information about the secret data to project
items if unspecified, each key-value pair in the Data field of the referenced
Secret will be projected into the volume as a file whose name is the

expirationSeconds is the requested duration of validity of the service
account token. As the token approaches expiration, the kubelet volume
plugin will proactively rotate the service account token. The kubelet will
start trying to rotate the token if the token is older than 80 percent of
its time to live or if the token is older than 24 hours.Defaults to 1 hour

Directories within the path are not affected by this setting.
This might be in conflict with other options that affect the file
mode, like fsGroup, and the result can be other mode bits set.
items If unspecified, each key-value pair in the Data field of the referenced
Secret will be projected into the volume as a file whose name is the
key and content is the value. If specified, the listed keys will be
projected into the specified paths, and unlisted keys will not be
present. If a key is specified which is not present in the Secret,
the volume setup will error unless it is marked optional. Paths must be
relative and may not contain the '..' path or start with '..'.
Maps a string key to a path within a volume.
key is the key to project.
mode is Optional: mode bits used to set permissions on this file.
Must be an octal value between 0000 and 0777 or a decimal value between 0 and 511.
YAML accepts both octal and decimal values, JSON requires decimal values for mode bits.
If not specified, the volume defaultMode will be used.

fsType is the filesystem type to mount.
Must be a filesystem type supported by the host operating system.
Ex. "ext4", "xfs", "ntfs". Implicitly inferred to be "ext4" if unspecified.
readOnly defaults to false (read/write). ReadOnly here will force
the ReadOnly setting in VolumeMounts.

credentials. If not specified, default values will be attempted.
volumeName is the human-readable name of the StorageOS volume. Volume
names are only unique within a namespace.

namespace is specified then the Pod's namespace will be used. This allows the
Kubernetes name scoping to be mirrored within StorageOS for tighter integration.
Set VolumeName to any name to override the default behaviour.
Set to "default" if you are not using namespaces within StorageOS.
Namespaces that do not pre-exist within StorageOS will be created.

Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
Standard list metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
continue may be set if the user set a limit on the number of items returned, and indicates that the server has more data available. The value is opaque and may be used to issue another request to the endpoint that served this list to retrieve the next set of available objects. Continuing a consistent list may not be possible if the server configuration has changed or more than a few minutes have passed. The resourceVersion field returned when using this continue value will be identical to the value in the first response, unless you have received this token from an error message.
remainingItemCount is the number of subsequent items in the list which are not included in this list response. If the list request contained label or field selectors, then the number of remaining items is unknown and the field will be left unset and omitted during serialization. If the list is complete (either because it is not chunking or because this is the last chunk), then there are no more remaining items and this field will be left unset and omitted during serialization. Servers older than v1.15 do not set this field. The intended use of the remainingItemCount is estimating the size of a collection. Clients should not rely on the remainingItemCount to be set or to be exact.
String that identifies the server's internal version of this object that can be used by clients to determine when objects have changed. Value must be treated as opaque by clients and passed unmodified back to the server. Populated by the system. Read-only.
