-Security context constraints (SCCs) have a priority field that affects the ordering when attempting to

-. Highest priority first, nil is considered a 0 priority
-. If priorities are equal, the SCCs will be sorted from most restrictive to least restrictive
-. If both priorities and restrictions are equal the SCCs will be sorted by name
+A priority value of `0` is the lowest possible priority. A nil priority is considered a `0`, or lowest, priority. Higher priority SCCs are moved to the front of the set when sorting.

 By default, the `anyuid` SCC granted to cluster administrators is given priority
