# We expect most Kubernetes teams to follow the Kubernetes docs and have these PSPs.
# * privileged (for kube-system namespace)
# * restricted (for all logged in users)
#
# PSPs are applied based on the first match alphabetically. `rook-ceph-operator` comes after
# `restricted` alphabetically, so we name this `00-rook-privileged`, so it stays somewhere
# close to the top and so `rook-system` gets the intended PSP. This may need to be renamed in
# environments with other `00`-prefixed PSPs.
