+# This policy enforces that all containers of a deployment has the image repo match the environment label of its namespace.
+# Except for "exempt" deployments, or any containers that do not belong to the "example.com" organization (e.g. common sidecars).
+# For example, if the namespace has a label of {"environment": "staging"}, all container images must be either staging.example.com/*
+# or do not contain "example.com" at all, unless the deployment has {"exempt": "true"} label.
