Description

When a kube-apiserver container is present (in containers or initContainers), the --enable-admission-plugins flag should include PodSecurityPolicy. The rule inspects the container command for kube-apiserver and reports a MissingAttribute if the flag does not contain PodSecurityPolicy. The admission control configuration file should also be correctly configured to enable the plugin.
