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.
