What is pod security policy and why is it important

Question

Why do we need a pod security policy in kubernetes?

Answer 1

• In Kubernetes, Pod Security Policies consists of settings & strategies that control the security features a pod has access to. 

• It is a type of cluster-level resource which helps in controlling security aspects of Pod.

• Since the pod security policy API (policy/v1beta1/podsecuritypolicy) is enabled independently of the admission controller, for existing clusters it is recommended that policies are added and authorized before enabling the admission controller.
