    policies.kyverno.io/description: The `exec` command may be used to gain shell access, or run other commands, in a Pod's container. While this can be useful for troubleshooting purposes, it could represent an attack vector and is discouraged. This policy blocks Pod exec commands to Pods beginning with the name `myapp-maintenance-`.
