Use crane to tag the image
Rather than docker pull,tag,push use crane to tag it direct in the repository.
Motivation:
- Since gitlab upgrade OTG0079595. docker push fails with
Bad parameters and missing X-Registry-Auth: EOF"I expect the hard coded docker 19.03 is too old to talk to the registry correctly. - There is a general move at CERN to stop using priviledged runners and this trivial task is not justified for them.
The crane method is inspired from gitlabci-examples/build_docker_image!12
In fact it looks from OTG0078219 that Dockerbuild Runners are going to be removed on 2nd of October anyway.
