Admission controllers

Admission controllers are modules that intercept requests to the API server after the request is authenticated and authorized. The controllers validate and mutate the request before modifying the state of the objects in the cluster. A controller can be both mutating and validating. If any of the controllers reject the request, the request is dropped immediately and an error is returned to the user so that the request will not be processed.

Admission controllers can be enabled by using the --enable-admission-plugins flag:

$ps aux | grep api
root      3460 17.0  8.6 496896 339432 ?       Ssl  06:53   0:09 kube-apiserver --advertise-address=192.168.99.106 --allow-privileged=true --authorization-mode=Node,RBAC --client-ca-file=/var/lib/minikube/certs/ca.crt --enable-admission-plugins=PodSecurityPolicy,NamespaceLifecycle,LimitRanger --enable-bootstrap-token-auth=true
