1 General
This is stuff I don't want to remember and don't want to forget! So I keep it here! BTW: I'm working with OKD current version (4.7)

2.1 SCC Review
- Get a list with pods and their assigned scc
oc get pod --all-namespaces | awk '{print $2 " -n "$1}' | grep -v NAME | while read p ; do echo "======= pod $p" ; oc describe pod $p | grep scc: ; done
- only show the interesting containers
oc get pod --all-namespaces | awk '{print $1 ","$2}' | grep -v NAME | while read p
do
namespace=$(echo $p | cut -d, -f1)
pod=$(echo $p | cut -d, -f2)
oc describe pod $pod -n $namespace | grep scc: | grep -v ": restricted" | while read perm
do
echo "$namespace -> $pod -> $perm"
done
done | column -t
