Overview

Package admissionregistration is the internal version of the API. AdmissionConfiguration and AdmissionPluginConfiguration are legacy static admission plugin configuration ValidatingWebhookConfiguration, and MutatingWebhookConfiguration are for the new dynamic admission controller configuration.

	// 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",

	//
	// 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",

	// SideEffects states whether this webhookk has side effects.
	// Acceptable values are: Unknown, None, Some, NoneOnDryRun
	// Webhooks with side effects MUST implement a reconciliation system, since a request may be
	// rejected by a future step in the admission change 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. Defaults to Unknown.
	// +optional
	SideEffects *SideEffectClass

	// 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.
	// +optional
	TimeoutSeconds *int32

	// 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 the webhook configuration has already been persisted with a version apiserver
	// does not understand, calls to the webhook will fail and be subject to the failure policy.
	// +optional
	AdmissionReviewVersions []string

type WebhookClientConfig 

type WebhookClientConfig struct {
	// `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.
	//
	// +optional
	URL *string

	// `service` is a reference to the service for this webhook. Either
	// `service` or `url` must be specified.
	//
	// If the webhook is running within the cluster, then you should use `service`.
	//
	// Port 443 will be used if it is open, otherwise it is an error.
	//
	// +optional
	Service *ServiceReference

	// `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.
