RUN mkdir /dockerregistry || :
COPY dockerregistry /dockerregistry/dockerregistry

redeploy-on-any-registry-code-change.sh

cd $ORIGIN_WSP
go build -o /var/tmp/dockerregistry/dockerregistry ./cmd/dockerregistry && oc scale --replicas=0 dc/docker-registry && oc scale --replicas=1 dc/docker-registry

Init

1. Save the Dockerfile to /var/tmp/dockerregistry/Dockerfile. Change the FROM line to match any docker-registry base image.
2. Build it with build-the-registry-image-from-Dockerfile.sh
3. Deploy the registry with redeploy-on-any-registry-code-change.sh

Usage

1. Do the changes to the docker registry codebase.
2. Redeploy the registry with redeploy-on-any-registry-code-change.sh
3. Test and repeat 😄
