How to deploy development build of image registry

Prerequisites

• An OpenShift cluster.
• Credentials from the app.ci cluster.
• A public image repository (for example, you can create a public repository on quay.io).

Logging into the app.ci cluster and its registry

1. Copy the login command from https://console-openshift-console.apps.ci.l2s4.p1.openshiftapps.com/ and run it

2. Rename the context for the app.ci cluster

   oc config rename-context "$(oc config current-context)" app.ci
   

3. Login into the registry registry.ci.openshift.org

   oc --context=app.ci whoami -t | docker login -u unused --password-stdin "$(oc --context=app.ci registry info --public=true)"
   

Switching the image registry operator into the Unmanaged mode

1. You'll need to change the image registry deployment manually, so disable the image registry operator

   oc patch configs.imageregistry cluster --type=merge -p '{"spec":{"managementState":"Unmanaged"}}'
   

Building and deploying a new container image

1. Go to the directory with the image registry sources

   cd ./openshift/image-registry
   

2. Build a new image

   docker build -f Dockerfile.rhel7 -t quay.io/rh-obulatov/image-registry .
   

3. Push the new image

   docker push quay.io/rh-obulatov/image-registry
   

4. Deploy the new build

   oc -n openshift-image-registry set image deploy/image-registry registry="$(docker inspect --format='{{index .RepoDigests 0}}' quay.io/rh-obulatov/image-registry)"
   

5. Wait until the pods use the new image

   oc -n openshift-image-registry get pods -l docker-registry=default -o custom-columns="NAME:.metadata.name,STATUS:.status.phase,IMAGE:.spec.containers[0].image"
   

6. Enjoy your registry!
