"PodSecurityPolicy" is an admission controller resource created to validate requests to create and update Pods on your cluster.
The "PodSecurityPolicy" defines a set of conditions that Pods must meet to be accepted by the cluster. The request to create or update a Pod can be rejected (or error out) if it doesn't meet the requirements in the PodSecurityPolicy.
We recommend you enable "PodSecurityPolicy" Controller on Kubernetes engine clusters.
pod_security_policy_config {
enabled = true
}
