Properties

PropertyTypeAttributesDescription
metadataIoK8SApimachineryPkgApisMetaV1ObjectMetaRequired, IdentifierObjectMeta is metadata that all persisted resources must have, which includes all objects users must create.
apiVersion'admissionregistration.k8s.io/v1'Read-only, Deploy-time constantAPIVersion 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
kind'ValidatingWebhookConfiguration'Read-only, Deploy-time constantKind 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
webhooksIoK8SApiAdmissionregistrationV1ValidatingWebhook[]Webhooks is a list of webhooks and the affected resources and operations.

IoK8SApimachineryPkgApisMetaV1ObjectMeta

PropertyTypeAttributesDescription
namestringRequired, Deploy-time constant, IdentifierName 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
annotationsIoK8SApimachineryPkgApisMetaV1ObjectMetaAnnotationsAnnotations 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
creationTimestampstringRead-onlyTime is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.
deletionGracePeriodSecondsintRead-onlyNumber 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.
deletionTimestampstringRead-onlyTime is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.
finalizersstring[]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.
generationintRead-onlyA sequence number representing a specific generation of the desired state. Populated by the system. Read-only.
labelsIoK8SApimachineryPkgApisMetaV1ObjectMetaLabelsMap 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
managedFieldsIoK8SApimachineryPkgApisMetaV1ManagedFieldsEntry[]Read-onlyManagedFields 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.
namespacestringDeploy-time constant, IdentifierNamespace 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
ownerReferencesIoK8SApimachineryPkgApisMetaV1OwnerReference[]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.
resourceVersionstringRead-onlyAn 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
selfLinkstringRead-onlyDeprecated: selfLink is a legacy read-only field that is no longer populated by the system.
uidstringRead-onlyUID 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

IoK8SApiAdmissionregistrationV1ValidatingWebhook

PropertyTypeAttributesDescription
admissionReviewVersionsstring[]RequiredAdmissionReviewVersions is an ordered list of preferred `AdmissionReview` versions the Webhook expects. API server will try to use first version in the list which it supports. If none of the versions specified in this list supported by API server, validation will fail for this object. If a persisted webhook configuration specifies allowed versions and does not include any versions known to the API Server, calls to the webhook will fail and be subject to the failure policy.
clientConfigIoK8SApiAdmissionregistrationV1WebhookClientConfigRequiredWebhookClientConfig contains the information to make a TLS connection with the webhook
namestringRequiredThe name of the admission webhook. Name should be fully qualified, e.g., imagepolicy.kubernetes.io, where "imagepolicy" is the name of the webhook, and kubernetes.io is the name of the organization. Required.
sideEffectsstringRequiredSideEffects states whether this webhook has side effects. Acceptable values are: None, NoneOnDryRun (webhooks created via v1beta1 may also specify Some or Unknown). Webhooks with side effects MUST implement a reconciliation system, since a request may be rejected by a future step in the admission chain and the side effects therefore need to be undone. Requests with the dryRun attribute will be auto-rejected if they match a webhook with sideEffects == Unknown or Some.
failurePolicystringFailurePolicy defines how unrecognized errors from the admission endpoint are handled - allowed values are Ignore or Fail. Defaults to Fail.
matchConditionsIoK8SApiAdmissionregistrationV1MatchCondition[]MatchConditions is a list of conditions that must be met for a request to be sent to this webhook. 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 webhook is skipped. 2. If ALL matchConditions evaluate to TRUE, the webhook is called. 3. If any matchCondition evaluates to an error (but none are FALSE): - If failurePolicy=Fail, reject the request - If failurePolicy=Ignore, the error is ignored and the webhook is skipped
matchPolicystringmatchPolicy defines how the "rules" 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 webhook. - 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 webhook. Defaults to "Equivalent"
namespaceSelectorIoK8SApimachineryPkgApisMetaV1LabelSelectorA label selector is a label query over a set of resources. The result of matchLabels and matchExpressions are ANDed. An empty label selector matches all objects. A null label selector matches no objects.
objectSelectorIoK8SApimachineryPkgApisMetaV1LabelSelectorA label selector is a label query over a set of resources. The result of matchLabels and matchExpressions are ANDed. An empty label selector matches all objects. A null label selector matches no objects.
rulesIoK8SApiAdmissionregistrationV1RuleWithOperations[]Rules describes what operations on what resources/subresources the webhook cares about. The webhook cares about an operation if it matches any Rule. However, in order to prevent ValidatingAdmissionWebhooks and MutatingAdmissionWebhooks from putting the cluster in a state which cannot be recovered from without completely disabling the plugin, ValidatingAdmissionWebhooks and MutatingAdmissionWebhooks are never called on admission requests for ValidatingWebhookConfiguration and MutatingWebhookConfiguration objects.
timeoutSecondsintTimeoutSeconds specifies the timeout for this webhook. After the timeout passes, the webhook call will be ignored or the API call will fail based on the failure policy. The timeout value must be between 1 and 30 seconds. Default to 10 seconds.

Additional properties of type string are allowed.

IoK8SApimachineryPkgApisMetaV1ManagedFieldsEntry

PropertyTypeAttributesDescription
apiVersionstringAPIVersion 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.
fieldsTypestringFieldsType is the discriminator for the different fields format and version. There is currently only one possible value: "FieldsV1"
fieldsV1anyAny object
managerstringManager is an identifier of the workflow managing these fields.
operationstringOperation is the type of operation which lead to this ManagedFieldsEntry being created. The only valid values for this field are 'Apply' and 'Update'.
subresourcestringSubresource 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.
timestringTime is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.

IoK8SApimachineryPkgApisMetaV1OwnerReference

PropertyTypeAttributesDescription
apiVersionstringRequiredAPI version of the referent.
kindstringRequiredKind of the referent. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
namestringRequiredName of the referent. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names#names
uidstringRequiredUID of the referent. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names#uids
blockOwnerDeletionboolIf 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.
controllerboolIf true, this reference points to the managing controller.

IoK8SApiAdmissionregistrationV1WebhookClientConfig

PropertyTypeAttributesDescription
caBundleany`caBundle` is a PEM encoded CA bundle which will be used to validate the webhook's server certificate. If unspecified, system trust roots on the apiserver are used.
serviceIoK8SApiAdmissionregistrationV1ServiceReferenceServiceReference holds a reference to Service.legacy.k8s.io
urlstring`url` gives the location of the webhook, in standard URL form (`scheme://host:port/path`). Exactly one of `url` or `service` must be specified. The `host` should not refer to a service running in the cluster; use the `service` field instead. The host might be resolved via external DNS in some apiservers (e.g., `kube-apiserver` cannot resolve in-cluster DNS as that would be a layering violation). `host` may also be an IP address. Please note that using `localhost` or `127.0.0.1` as a `host` is risky unless you take great care to run this webhook on all hosts which run an apiserver which might need to make calls to this webhook. Such installs are likely to be non-portable, i.e., not easy to turn up in a new cluster. The scheme must be "https"; the URL must begin with "https://". A path is optional, and if present may be any string permissible in a URL. You may use the path to pass an arbitrary string to the webhook, for example, a cluster identifier. Attempting to use a user or basic auth e.g. "user:password@" is not allowed. Fragments ("#...") and query parameters ("?...") are not allowed, either.

IoK8SApiAdmissionregistrationV1MatchCondition

PropertyTypeAttributesDescription
expressionstringRequiredExpression 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.
namestringRequiredName 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.

IoK8SApimachineryPkgApisMetaV1LabelSelector

PropertyTypeAttributesDescription
matchExpressionsIoK8SApimachineryPkgApisMetaV1LabelSelectorRequirement[]matchExpressions is a list of label selector requirements. The requirements are ANDed.
matchLabelsIoK8SApimachineryPkgApisMetaV1LabelSelectorMatchLabelsmatchLabels 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.

IoK8SApiAdmissionregistrationV1RuleWithOperations

PropertyTypeAttributesDescription
apiGroupsstring[]APIGroups is the API groups the resources belong to. '' is all groups. If '' is present, the length of the slice must be one. Required.
apiVersionsstring[]APIVersions is the API versions the resources belong to. '' is all versions. If '' is present, the length of the slice must be one. Required.
operationsstring[]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.
resourcesstring[]Resources 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.
scopestringscope 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 "*".

IoK8SApiAdmissionregistrationV1ServiceReference

PropertyTypeAttributesDescription
namestringRequired`name` is the name of the service. Required
namespacestringRequired`namespace` is the namespace of the service. Required
pathstring`path` is an optional URL path which will be sent in any request to this service.
portintIf specified, the port on the service that hosting webhook. Default to 443 for backward compatibility. `port` should be a valid port number (1-65535, inclusive).

IoK8SApimachineryPkgApisMetaV1LabelSelectorRequirement

PropertyTypeAttributesDescription
keystringRequiredkey is the label key that the selector applies to.
operatorstringRequiredoperator represents a key's relationship to a set of values. Valid operators are In, NotIn, Exists and DoesNotExist.
valuesstring[]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.
