Supported Admission Controllers

Find out about the admission controllers that are turned on in Kubernetes clusters you create using Kubernetes Engine (OKE).

The Kubernetes version you select when you create a cluster using Kubernetes Engine determines the default set of admission controllers that are turned on in the created cluster. The set follows the recommendation given in the Kubernetes documentation for that version. This topic shows the supported admission controllers, the Kubernetes versions in which they are supported, and the order in which they run in the Kubernetes API server.

Note that if you install other admission controllers in a way that mutates or rejects requests in the kube-system namespace, the Kubernetes control plane components might stop functioning or behave unexpectedly. For more information, see Avoiding operating on the kube-system namespace in the Kubernetes documentation.
