How can I check which admission controllers are enabled by default on the cluster using some command like kubectl.
You can try using the following command Kubectl cluster-info dump | grep -i admission
There is no subcommand to list the enable admission controller with kubectl.
Nevertheless, you can get this information from kube-apiserver admission controller enabled-by-default
kube-apiserver -h | grep enable-admission-plugins
for k8s 1.16
