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
Name of the referent. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names#names
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.
Populated by the system. Read-only. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names#uids
GeneratingPolicySpec is the specification of the desired behavior of the GeneratingPolicy.
EvaluationConfiguration defines the configuration for the policy evaluation.
Admission controls policy evaluation during admission.
Enabled controls if rules are applied during admission.
Optional. Default value is "true".
GenerateExisting defines the configuration for generating resources for existing triggeres.
Enabled controls whether to trigger the policy for existing resources
If is set to "true" the policy will be triggered and applied to existing matched resources.
Optional. Defaults to "false" if not specified.
OrphanDownstreamOnPolicyDelete defines the configuration for orphaning downstream resources on policy delete.
Enabled controls whether generated resources should be deleted when the policy that generated
them is deleted with synchronization enabled. This option is only applicable to generate rules of the data type.
Optional. Defaults to "false" if not specified.
Synchronization defines the configuration for the synchronization of generated resources.
Enabled controls if generated resources should be kept in-sync with their source resource.
If Synchronize is set to "true" changes to generated resources will be overwritten with resource
data from Data or the resource specified in the Clone declaration.
Optional. Defaults to "false" if not specified.
Generation defines a set of CEL expressions that will be evaluated to generate resources.
Required.
Must contain a minimum of 1 items
Generation defines the configuration for the generation of resources.
Expression is a CEL expression that takes a list of resources to be generated.
MatchConditions is a list of conditions that must be met for a request to be validated.
Match conditions filter requests that have already been matched by the rules,
namespaceSelector, and objectSelector. An empty list of matchConditions matches all requests.
There are a maximum of 64 match conditions allowed.
The exact matching logic is (in order):
1. If ANY matchCondition evaluates to FALSE, the policy is skipped.
2. If ALL matchConditions evaluate to TRUE, the policy is evaluated.
3. If any matchCondition evaluates to an error (but none are FALSE):
- If failurePolicy=Fail, reject the request
- If failurePolicy=Ignore, the policy is skipped
MatchCondition represents a condition which must by fulfilled for a request to be sent to a webhook.
Expression represents the expression which will be evaluated by CEL. Must evaluate to bool.
CEL expressions have access to the contents of the AdmissionRequest and Authorizer, organized into CEL variables:
'object' - The object from the incoming request. The value is null for DELETE requests.
'oldObject' - The existing object. The value is null for CREATE requests.
'request' - Attributes of the admission request(/pkg/apis/admission/types.go#AdmissionRequest).
'authorizer' - A CEL Authorizer. May be used to perform authorization checks for the principal (user or service account) of the request.
See https://pkg.go.dev/k8s.io/apiserver/pkg/cel/library#Authz
'authorizer.requestResource' - A CEL ResourceCheck constructed from the 'authorizer' and configured with the
request resource.
Documentation on CEL: https://kubernetes.io/docs/reference/using-api/cel/
Required.
Name is an identifier for this match condition, used for strategic merging of MatchConditions,
as well as providing an identifier for logging purposes. A good name should be descriptive of
the associated expression.
Name must be a qualified name consisting of alphanumeric characters, '-', '' or '.', and
must start and end with an alphanumeric character (e.g. 'MyName', or 'my.name', or
'123-abc', regex used for validation is '([A-Za-z0-9][-A-Za-z0-9.]*)?[A-Za-z0-9]') with an
optional DNS subdomain prefix and '/' (e.g. 'example.com/MyName')
Required.
MatchConstraints specifies what resources will trigger this policy.
The AdmissionPolicy cares about a request if it matches all Constraints.
Required.
ExcludeResourceRules describes what operations on what resources/subresources the ValidatingAdmissionPolicy should not care about.
The exclude rules take precedence over include rules (if a resource matches both, it is excluded)
NamedRuleWithOperations is a tuple of Operations and Resources with ResourceNames.
APIGroups is the API groups the resources belong to. '' is all groups.
If '' is present, the length of the slice must be one.
Required.
APIVersions is the API versions the resources belong to. '' is all versions.
If '' is present, the length of the slice must be one.
Required.
Operations is the operations the admission hook cares about - CREATE, UPDATE, DELETE, CONNECT or *
for all of those operations and any future admission operations that are added.
If '*' is present, the length of the slice must be one.
Required.
OperationType specifies an operation for a request.
ResourceNames is an optional white list of names that the rule applies to. An empty set means that everything is allowed.
No Additional ItemsResources is a list of resources this rule applies to.
For example:
'pods' means pods.
'pods/log' means the log subresource of pods.
'' means all resources, but not subresources.
'pods/' means all subresources of pods.
'/scale' means all scale subresources.
'/*' means all resources and their subresources.
If wildcard is present, the validation rule will ensure resources do not
overlap with each other.
Depending on the enclosing object, subresources might not be allowed.
Required.
scope specifies the scope of this rule.
Valid values are "Cluster", "Namespaced", and ""
"Cluster" means that only cluster-scoped resources will match this rule.
Namespace API objects are cluster-scoped.
"Namespaced" means that only namespaced resources will match this rule.
"" means that there are no scope restrictions.
Subresources match the scope of their parent resource.
Default is "*".
matchPolicy defines how the "MatchResources" list is used to match incoming requests.
Allowed values are "Exact" or "Equivalent".
Exact: match a request only if it exactly matches a specified rule.
For example, if deployments can be modified via apps/v1, apps/v1beta1, and extensions/v1beta1,
but "rules" only included apiGroups:["apps"], apiVersions:["v1"], resources: ["deployments"],
a request to apps/v1beta1 or extensions/v1beta1 would not be sent to the ValidatingAdmissionPolicy.
Equivalent: match a request if modifies a resource listed in rules, even via another API group or version.
For example, if deployments can be modified via apps/v1, apps/v1beta1, and extensions/v1beta1,
and "rules" only included apiGroups:["apps"], apiVersions:["v1"], resources: ["deployments"],
a request to apps/v1beta1 or extensions/v1beta1 would be converted to apps/v1 and sent to the ValidatingAdmissionPolicy.
Defaults to "Equivalent"
NamespaceSelector decides whether to run the admission control policy on an object based
on whether the namespace for that object matches the selector. If the
object itself is a namespace, the matching is performed on
object.metadata.labels. If the object is another cluster scoped resource,
it never skips the policy.
For example, to run the webhook on any objects whose namespace is not
associated with "runlevel" of "0" or "1"; you will set the selector as
follows:
"namespaceSelector": {
"matchExpressions": [
{
"key": "runlevel",
"operator": "NotIn",
"values": [
"0",
"1"
]
}
]
}
If instead you want to only run the policy on any objects whose
namespace is associated with the "environment" of "prod" or "staging";
you will set the selector as follows:
"namespaceSelector": {
"matchExpressions": [
{
"key": "environment",
"operator": "In",
"values": [
"prod",
"staging"
]
}
]
}
See
https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/
for more examples of label selectors.
Default to the empty LabelSelector, which matches everything.
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: stringObjectSelector decides whether to run the validation based on if the
object has matching labels. objectSelector is evaluated against both
the oldObject and newObject that would be sent to the cel validation, and
is considered to match if either object matches the selector. A null
object (oldObject in the case of create, or newObject in the case of
delete) or an object that cannot have labels (like a
DeploymentRollback or a PodProxyOptions object) is not considered to
match.
Use the object selector only if the webhook is opt-in, because end
users may skip the admission webhook by setting the labels.
Default to the empty LabelSelector, which matches everything.
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,

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: stringResourceRules describes what operations on what resources/subresources the ValidatingAdmissionPolicy matches.
The policy cares about an operation if it matches any Rule.
NamedRuleWithOperations is a tuple of Operations and Resources with ResourceNames.
APIGroups is the API groups the resources belong to. '' is all groups.
If '' is present, the length of the slice must be one.
Required.
APIVersions is the API versions the resources belong to. '' is all versions.
If '' is present, the length of the slice must be one.
Required.
Operations is the operations the admission hook cares about - CREATE, UPDATE, DELETE, CONNECT or *
for all of those operations and any future admission operations that are added.
If '*' is present, the length of the slice must be one.
Required.
OperationType specifies an operation for a request.
ResourceNames is an optional white list of names that the rule applies to. An empty set means that everything is allowed.
No Additional ItemsResources is a list of resources this rule applies to.
For example:
'pods' means pods.
'pods/log' means the log subresource of pods.
'' means all resources, but not subresources.
'pods/' means all subresources of pods.
'/scale' means all scale subresources.
'/*' means all resources and their subresources.
If wildcard is present, the validation rule will ensure resources do not
overlap with each other.
Depending on the enclosing object, subresources might not be allowed.
Required.
scope specifies the scope of this rule.
Valid values are "Cluster", "Namespaced", and ""
"Cluster" means that only cluster-scoped resources will match this rule.
Namespace API objects are cluster-scoped.
"Namespaced" means that only namespaced resources will match this rule.
"" means that there are no scope restrictions.
Subresources match the scope of their parent resource.
Default is "*".
Variables contain definitions of variables that can be used in composition of other expressions.
Each variable is defined as a named CEL expression.
The variables defined here will be available under variables in other expressions of the policy
except MatchConditions because MatchConditions are evaluated before the rest of the policy.
The expression of a variable can refer to other variables defined earlier in the list but not those after.
Thus, Variables must be sorted by the order of first appearance and acyclic.
Variable is the definition of a variable that is used for composition. A variable is defined as a named expression.
Expression is the expression that will be evaluated as the value of the variable.
The CEL expression has access to the same identifiers as the CEL expressions in Validation.
Name is the name of the variable. The name must be a valid CEL identifier and unique among all variables.
The variable can be accessed in other expressions through variables
For example, if name is "foo", the variable will be available as variables.foo
WebhookConfiguration defines the configuration for the webhook.
TimeoutSeconds specifies the maximum time in seconds allowed to apply this policy.
After the configured time expires, the admission request may fail, or may simply ignore the policy results,
based on the failure policy. The default timeout is 10s, the value must be between 1 and 30 seconds.
Status contains policy runtime data.
ConditionStatus is the shared status across all policy types
Condition contains details for one aspect of the current state of this API Resource.
lastTransitionTime is the last time the condition transitioned from one status to another.
This should be when the underlying condition changed. If that is not known, then using the time when the API field changed is acceptable.
message is a human readable message indicating details about the transition.
This may be an empty string.
Must be at most 32768 characters long
observedGeneration represents the .metadata.generation that the condition was set based upon.
For instance, if .metadata.generation is currently 12, but the .status.conditions[x].observedGeneration is 9, the condition is out of date
with respect to the current state of the instance.
Value must be greater or equal to 0
reason contains a programmatic identifier indicating the reason for the condition's last transition.
Producers of specific condition types may define expected values and meanings for this field,
and whether the values are considered a guaranteed API.
The value should be a CamelCase string.
This field may not be empty.
^[A-Za-z]([A-Za-z0-9_,:]*[A-Za-z0-9_])?$
Must be at least 1 characters long
Must be at most 1024 characters long
status of the condition, one of True, False, Unknown.
type of condition in CamelCase or in foo.example.com/CamelCase.
Must match regular expression:^([a-z0-9]([-a-z0-9]*[a-z0-9])?(\.[a-z0-9]([-a-z0-9]*[a-z0-9])?)*/)?(([A-Za-z0-9][-A-Za-z0-9_.]*)?[A-Za-z0-9])$
Must be at most 316 characters long
Message is a human readable message indicating details about the generation of ValidatingAdmissionPolicy/MutatingAdmissionPolicy
It is an empty string when ValidatingAdmissionPolicy/MutatingAdmissionPolicy is successfully generated.
The ready of a policy is a high-level summary of where the policy is in its lifecycle.
The conditions array, the reason and message fields contain more detail about the policy's status.
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.
