Pushing to an OpenShift registry

How to setup an OpenShift registry

• Create registry with oadm

oadm registry --latest-images --create \
              --credentials=/var/lib/openshift/openshift.local.config/master/openshift-registry.kubeconfig

• Create route (optional, alternatively you can use also the internal ip of the registry service later)

cat <<EOF | oc create -f -
{
    "kind": "Route",
    "apiVersion": "v1",
    "metadata": {
        "name": "docker-registry-route"
    },
    "spec": {
        "host": "docker-registry.vagrant.f8",
        "to": {
            "kind": "Service",
            "name": "docker-registry"
        }
    }
}
EOF

• Create image

docker build . -t docker-registry.vagrant.f8:80/foo/test

• Add an OpenShift project with username part of your image

oc new-project foo

• Login in to docker with a use which has access to the created project 'foo'

docker login -u admin -p $(oc whoami -t) docker-registry.vagrant.f8:80

• Push

docker push docker-registry.vagrant.f8:80/foo/test

See also the OpenShift Documentation

For the docker-maven-plugin you can use mvn docker:build for creating your image and

mvn docker:push -Ddocker.registry=docker-registry.vagrant.f8:80 \
                            -Ddocker.username=$(oc whoami) \
                            -Ddocker.password=$(oc whoami -t)

considering that you are logged in as foo.

The most important things are:

• You must login with a user having permissions on the project to which the image belongs (admin is fine)
• An image belongs to the project with the username part of the image. E.g. Image fabric8/blubber:latest belongs to the project fabric8 (which must exist)
• You must login with docker and don't forget the registry address as last argument to docker login
