dockerhub private repo authentication

[mayacr86]

Is there a way to set the authentication for a private repository on dockerhub?

dockerRepository := Some("myRepo")

dockerRepositoryAuth := Some("myAuthToken") ???

If not, what would be a work around? I want to automate the process of docker:publish with TeamCity.

I'm afraid you have to configure your docker daemon. This is from our gitter chat:

Because there didn’t seem to be a way to inject auth information without altering the environment, the plugin punts on the issue, and requires you to have run docker login as the build user, for any repositories requiring authentication.
Your local repository won’t need any authentication anyway (at least, I’ve never seen it), so it doesn’t matter until you run sbt docker:publish

and

It just assumes thedocker command works. It’s a thin wrapper around docker build and docker push, so you can always run those commands manually.

Yes, the problem was that you can't provide authentication on a once-off basis for pushing, without it being added to ~/.docker/config.json. A permanent change to the environment is not what somebody might expect (and could even be a security issue), so this feature was left out.

You can manually run the command to log into a Docker server, if you have the ability to run particular commands in the environment:

$ docker login -h

Usage: docker login [OPTIONS] [SERVER]

Register or log in to a Docker registry server, if no server is
specified "https://index.docker.io/v1/" is the default.

  -e, --email=       Email
  --help=false       Print usage
  -p, --password=    Password
  -u, --username=    Username

Thanks for the quick response :)

Well, it does make sense that a plugin shouldn't change to the environment... I was just hoping for an easier way to do it :p

Right now, I'm using the following command as one of the Build Steps on my TeamCity deployment process:

$ docker login -e [userEmail] -p [userPass] -u [userName]

After that step, I do the docker:publish and it does the trick!

Thanks anyway!

There is small section in the documentation.

I leave this issue open to extend the docs there.

It would be nice if the word "password" was near the text:

It is currently not possible to provide authentication for Docker repositories from within the build.

So when someone is searching the page, they can find it.

Sounds reasonable. Would you like to open a pull request 😎?

Would have saved me some time as well...
