Linkerd and Pod Security Policies (PSP)

Pod Security Policies have been deprecated in Kuberenetes v1.21 and removed in v1.25. However, for users who still want them, the Linkerd control plane comes with its own minimally privileged Pod Security Policy and the associated RBAC resources which can be optionally created by setting the --set enablePSP=true flag during Linkerd install or upgrade, or by using the enablePSP Helm value.
