-## Gatekeeper
-
-The gatekeeper `values` section should resemble below when deploying to production.
-
-```yaml
-# OPA Gatekeeper
-#
-gatekeeper:
-  # -- Toggle deployment of OPA Gatekeeper.
-  enabled: true
-  git:
-    repo: https://repo1.dso.mil/big-bang/product/packages/policy.git
-    path: "./chart"
-    tag: "3.5.1-bb.2"
-
-  # -- Flux reconciliation overrides specifically for the OPA Gatekeeper Package
-  flux: {}
-
-  # -- Values to passthrough to the gatekeeper chart: https://repo1.dso.mil/big-bang/product/packages/policy.git
-  values:
-    violations:
-      allowedDockerRegistries:
-        match:
-          excludedNamespaces:
-            - kube-system # ignored as the kubernetes distro cannot be controlled
-
-  # -- Post Renderers.  See docs/postrenders.md
-  postRenderers: []
-```
-
-To validate it was deployed correctly on your cluster run the following command:
-
-`kubectl get k8sallowedrepos.constraints.gatekeeper.sh/allowed-docker-registries -o yaml`
-
-You should only see `kube-system` under `excludedNamespaces` section.
-
-Output:
-
-```yaml
-  name: allowed-docker-registries
-  resourceVersion: "10390"
-  uid: b51b3887-3cf8-4495-b37e-fb8ef31755db
