11      Images coming from certain registries require authentication in order to pull them,
12      and the kubelet uses this information in the form of an imagePullSecret to pull
13      those images on behalf of your Pod. This policy searches for images coming from a
14      registry called `corp.reg.com` referenced by either one of the containers or one 
15      of the init containers and, if found, will mutate the Pod to add an
16      imagePullSecret called `my-secret`.
