-### Private project support
-
-CAUTION: **Caution:** Private project support in Auto DevOps is experimental.
-
-When a project has been marked as private, GitLab's [Container
-Registry][container-registry] requires authentication when downloading
-containers. Auto DevOps will automatically provide the required authentication
-information to Kubernetes, allowing temporary access to the registry.
-Authentication credentials will be valid while the pipeline is running, allowing
-for a successful initial deployment.
-
-After the pipeline completes, Kubernetes will no longer be able to access the
-Container Registry. **Restarting a pod, scaling a service, or other actions which
-require on-going access to the registry may fail**. On-going secure access is
-planned for a subsequent release.

 ### Private registry support
 
 There is no documented way of using private container registry with Auto DevOps.
