OpenShift Tricks

Login to the container registry of a Project/Namespace

The IMAGE_STREAM_URL needs to be taken from the "Public image repository" attribute of the ImageStream in OpenShift, but without the last part.

E.g. if the "Public image repository" of the ImageStream "sample-application" would be default-route-openshift-image-registry.apps.my-cluster.com/ocp0000001/sample-application you need to take simply default-route-openshift-image-registry.apps.my-cluster.com/ocp0000001 for the IMAGE_STREAM_URL.

docker login -u <USERNAME> -e <EMAIL> -p $(oc whoami -t) <IMAGE_STREAM_URL>
