Google Container Registry: Authentication fault

[James Green]

We are using latest stable Jenkins and trying to push images to the Google Container Registry which is basically a private Docker image storage service.

I can push using their 'gcloud' command line tool no problem. But I cannot get Jenkins to push successfully - we see authentication failures.

We have https://wiki.jenkins-ci.org/display/JENKINS/Google+Container+Registry+Auth+Plugin installed.

Does anyone have this working? If so would it be possible to get some screenshots as the docs are a little vague...

Thanks,

James
