Types

type AdmissionRequest

type AdmissionRequest struct {
	// UID is an identifier for the individual request/response. It allows us to distinguish instances of requests which are
	// otherwise identical (parallel requests, requests when earlier requests did not modify etc)
	// The UID is meant to track the round trip (request/response) between the KAS and the WebHook, not the user request.
	// It is suitable for correlating log entries between the webhook and apiserver, for either auditing or debugging.
	UID types.UID
	// Kind is the fully-qualified type of object being submitted (for example, v1.Pod or autoscaling.v1.Scale)
	Kind metav1.GroupVersionKind
	// Resource is the fully-qualified resource being requested (for example, v1.pods)
	Resource metav1.GroupVersionResource
	// SubResource is the subresource being requested, if any (for example, "status" or "scale")
	// +optional
	SubResource string

	// RequestKind is the fully-qualified type of the original API request (for example, v1.Pod or autoscaling.v1.Scale).
	// If this is specified and differs from the value in "kind", an equivalent match and conversion was performed.
	//
	// For example, if deployments can be modified via apps/v1 and apps/v1beta1, and a webhook registered a rule of
	// `apiGroups:["apps"], apiVersions:["v1"], resources: ["deployments"]` and `matchPolicy: Equivalent`,
	// an API request to apps/v1beta1 deployments would be converted and sent to the webhook
	// with `kind: {group:"apps", version:"v1", kind:"Deployment"}` (matching the rule the webhook registered for),
	// and `requestKind: {group:"apps", version:"v1beta1", kind:"Deployment"}` (indicating the kind of the original API request).
	//
	// See documentation for the "matchPolicy" field in the webhook configuration type for more details.
	// +optional
	RequestKind *metav1.GroupVersionKind
	// RequestResource is the fully-qualified resource of the original API request (for example, v1.pods).

	// RequestSubResource is the name of the subresource of the original API request, if any (for example, "status" or "scale")

	// See documentation for the "matchPolicy" field in the webhook configuration type.
	// +optional
	RequestSubResource string

	// Name is the name of the object as presented in the request.  On a CREATE operation, the client may omit name and
	// rely on the server to generate the name.  If that is the case, this method will return the empty string.
	// +optional
	Name string
	// Namespace is the namespace associated with the request (if any).
	// +optional
	Namespace string
	// Operation is the operation being performed. This may be different than the operation
	// requested. e.g. a patch can result in either a CREATE or UPDATE Operation.
	Operation Operation
	// UserInfo is information about the requesting user
	UserInfo authentication.UserInfo
	// Object is the object from the incoming request prior to default values being applied
	// +optional
	Object runtime.Object
	// OldObject is the existing object. Only populated for UPDATE requests.
	// +optional
	OldObject runtime.Object
	// DryRun indicates that modifications will definitely not be persisted for this request.
	// Calls to webhooks must have no side effects if DryRun is true.
	// Defaults to false.
	// +optional
	DryRun *bool
	// Options is the operation option structure of the operation being performed.
	// e.g. `meta.k8s.io/v1.DeleteOptions` or `meta.k8s.io/v1.CreateOptions`. This may be
	// different than the options the caller provided. e.g. for a patch request the performed
	// Operation might be a CREATE, in which case the Options will a
	// `meta.k8s.io/v1.CreateOptions` even though the caller provided `meta.k8s.io/v1.PatchOptions`.
	// +optional
