== Specification

[cols="1,1,1",options="header"]
|===
| Property | Type | Description

| `apiVersion`
| `string`
| 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

| `kind`
| `string`
| 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

| `webhooks`
| `array`
| Webhooks is a list of webhooks and the affected resources and operations.

| `webhooks[]`

Type::
  `object`

Required::
  - `name`
  - `clientConfig`
  - `sideEffects`
  - `admissionReviewVersions`



[cols="1,1,1",options="header"]
|===
| Property | Type | Description

| `admissionReviewVersions`
| `array (string)`
| AdmissionReviewVersions 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.

| `clientConfig`
| `object`
| WebhookClientConfig contains the information to make a TLS connection with the webhook

| `failurePolicy`
| `string`
| FailurePolicy defines how unrecognized errors from the admission endpoint are handled - allowed values are Ignore or Fail. Defaults to Fail.

Possible enum values:
 - `"Fail"` means that an error calling the webhook causes the admission to fail.
 - `"Ignore"` means that an error calling the webhook is ignored.

| `matchConditions`
| `array`
| 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

This is an alpha feature and managed by the AdmissionWebhookMatchConditions feature gate.

| `matchConditions[]`
| `object`
| MatchCondition represents a condition which must by fulfilled for a request to be sent to a webhook.

| `matchPolicy`
| `string`
| matchPolicy 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"

Possible enum values:
 - `"Equivalent"` means requests should be sent to the webhook if they modify a resource listed in rules via another API group or version.
 - `"Exact"` means requests should only be sent to the webhook if they exactly match a given rule.

| `name`
| `string`
| The 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.

| `namespaceSelector`
| xref:../objects/index.adoc#io.k8s.apimachinery.pkg.apis.meta.v1.LabelSelector[`LabelSelector`]
| NamespaceSelector decides whether to run the webhook 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 webhook.

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 webhook 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.

| `objectSelector`
| xref:../objects/index.adoc#io.k8s.apimachinery.pkg.apis.meta.v1.LabelSelector[`LabelSelector`]
| ObjectSelector decides whether to run the webhook based on if the object has matching labels. objectSelector is evaluated against both the oldObject and newObject that would be sent to the webhook, 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.

| `rules`
| `array`
| 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.

| `rules[]`
| `object`
| RuleWithOperations is a tuple of Operations and Resources. It is recommended to make sure that all the tuple expansions are valid.

| `sideEffects`
| `string`
| SideEffects 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.

Possible enum values:
 - `"None"` means that calling the webhook will have no side effects.
 - `"NoneOnDryRun"` means that calling the webhook will possibly have side effects, but if the request being reviewed has the dry-run attribute, the side effects will be suppressed.
 - `"Some"` means that calling the webhook will possibly have side effects. If a request with the dry-run attribute would trigger a call to this webhook, the request will instead fail.
 - `"Unknown"` means that no information is known about the side effects of calling the webhook. If a request with the dry-run attribute would trigger a call to this webhook, the request will instead fail.

| `timeoutSeconds`
| `integer`
| TimeoutSeconds 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.

  `object`




[cols="1,1,1",options="header"]
|===
| Property | Type | Description

| `caBundle`
| `string`
| `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.

| `service`
| `object`
| ServiceReference holds a reference to Service.legacy.k8s.io

| `url`
| `string`
| `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.

Required.

| `name`
| `string`
| 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')

| Property | Type | Description

| `apiGroups`
| `array (string)`
| 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`
| `array (string)`
| 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`
| `array (string)`
| 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.

| `resources`
| `array (string)`
| 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.

| `scope`
| `string`
| 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 "\*".

HTTP method::
  `DELETE`

Description::
  delete collection of ValidatingWebhookConfiguration


.Query parameters
[cols="1,1,2",options="header"]
|===
| Parameter | Type | Description
| `continue`
| `string`
| The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the &quot;next key&quot;.

This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
| `dryRun`
| `string`
| When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
| `fieldSelector`
| `string`
| A selector to restrict the list of returned objects by their fields. Defaults to everything.
| `gracePeriodSeconds`
| `integer`
| The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
| `labelSelector`
| `string`
| A selector to restrict the list of returned objects by their labels. Defaults to everything.
| `limit`
| `integer`
| limit is a maximum number of responses to return for a list call. If more items exist, the server will set the &#x60;continue&#x60; field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true.

The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
| `orphanDependents`
| `boolean`
| Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the &quot;orphan&quot; finalizer will be added to/removed from the object&#x27;s finalizers list. Either this field or PropagationPolicy may be set, but not both.
| `propagationPolicy`
| `string`
| Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: &#x27;Orphan&#x27; - orphan the dependents; &#x27;Background&#x27; - allow the garbage collector to delete the dependents in the background; &#x27;Foreground&#x27; - a cascading policy that deletes all dependents in the foreground.
| `resourceVersion`
| `string`
| resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details.

Defaults to unset
| `resourceVersionMatch`
| `string`
| resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details.

Defaults to unset
| `sendInitialEvents`
| `boolean`
| &#x60;sendInitialEvents&#x3D;true&#x60; may be set together with &#x60;watch&#x3D;true&#x60;. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic &quot;Bookmark&quot; event  will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with &#x60;&quot;k8s.io/initial-events-end&quot;: &quot;true&quot;&#x60; annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched.

When &#x60;sendInitialEvents&#x60; option is set, we require &#x60;resourceVersionMatch&#x60; option to also be set. The semantic of the watch request is as following: - &#x60;resourceVersionMatch&#x60; &#x3D; NotOlderThan
  is interpreted as &quot;data at least as new as the provided &#x60;resourceVersion&#x60;&quot;
  and the bookmark event is send when the state is synced
  to a &#x60;resourceVersion&#x60; at least as fresh as the one provided by the ListOptions.
  If &#x60;resourceVersion&#x60; is unset, this is interpreted as &quot;consistent read&quot; and the
  bookmark event is send when the state is synced at least to the moment
  when request started being processed.
- &#x60;resourceVersionMatch&#x60; set to any other value or unset
  Invalid error is returned.

Defaults to true if &#x60;resourceVersion&#x3D;&quot;&quot;&#x60; or &#x60;resourceVersion&#x3D;&quot;0&quot;&#x60; (for backward compatibility reasons) and to false otherwise.
| `timeoutSeconds`
| `integer`
| Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.

| fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present.

.Global query parameters
[cols="1,1,2",options="header"]
|===
| Parameter | Type | Description
| `allowWatchBookmarks`
| `boolean`
| allowWatchBookmarks requests watch events with type &quot;BOOKMARK&quot;. Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server&#x27;s discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
| `continue`
| `string`
| The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the &quot;next key&quot;.

This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
| `fieldSelector`
| `string`
| A selector to restrict the list of returned objects by their fields. Defaults to everything.
| `labelSelector`
| `string`
| A selector to restrict the list of returned objects by their labels. Defaults to everything.
| `limit`
| `integer`
| limit is a maximum number of responses to return for a list call. If more items exist, the server will set the &#x60;continue&#x60; field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true.

The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
| `pretty`
| `string`
| If &#x27;true&#x27;, then the output is pretty printed.
| `resourceVersion`
| `string`
| resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details.

Defaults to unset
| `resourceVersionMatch`
| `string`
| resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details.

Defaults to unset
| `sendInitialEvents`
| `boolean`
| &#x60;sendInitialEvents&#x3D;true&#x60; may be set together with &#x60;watch&#x3D;true&#x60;. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic &quot;Bookmark&quot; event  will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with &#x60;&quot;k8s.io/initial-events-end&quot;: &quot;true&quot;&#x60; annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched.

When &#x60;sendInitialEvents&#x60; option is set, we require &#x60;resourceVersionMatch&#x60; option to also be set. The semantic of the watch request is as following: - &#x60;resourceVersionMatch&#x60; &#x3D; NotOlderThan
  is interpreted as &quot;data at least as new as the provided &#x60;resourceVersion&#x60;&quot;
  and the bookmark event is send when the state is synced
  to a &#x60;resourceVersion&#x60; at least as fresh as the one provided by the ListOptions.
  If &#x60;resourceVersion&#x60; is unset, this is interpreted as &quot;consistent read&quot; and the
  bookmark event is send when the state is synced at least to the moment
  when request started being processed.
- &#x60;resourceVersionMatch&#x60; set to any other value or unset
  Invalid error is returned.

Defaults to true if &#x60;resourceVersion&#x3D;&quot;&quot;&#x60; or &#x60;resourceVersion&#x3D;&quot;0&quot;&#x60; (for backward compatibility reasons) and to false otherwise.
| `timeoutSeconds`
| `integer`
| Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.

| Watch for changes to the described resources and return them as a stream of add, update, and remove notifications. Specify resourceVersion.
