Auth Support

[ahromis]

I haven't been able to get swarm to work with a registry that requires authentication. I logged in from each node, and from swarm itself but it keeps telling me image not found. I can docker pull from each node individually and then launch them via swarm. It also works fine with public images.

It might just not be implemented yet. Are there plans to have auth support in the near future? Thanks.

Hi @ahromis yes, we have plan to do it, currently it's unsupported because, swarm is actually pulling the images instead of letting the client pull.

This should be solved in #349

Cheers.

Same here. I built swarm locally from the latest master. It still fails.
I'm running the docker daemon as root on all hosts and have /root/.dockercfg correctly set up.

@csabapalfi you'll have to docker pull first to pull your private image on all hosts

[csabapalfi]

Yeah, I ended up with just doing docker pull locally on all swarm hosts via ansible.

I meant that you can do docker pull on swarm, it will pull on all boxes.

I built swarm from master and tried pulling an image from a private registry from the manager. It looks like it tried the pull on all 3 swarm agents instead of giving a not implemented error, but each node still says authentication required. I verified the nodes are all logged in and I can pull the image from the private registry on the nodes. @vieux, it looks like you implied the pull should work so I just wanted to verify.

I can't pull against an a private, authenticated registry either.

It looks like swam isn't passing along the X-Registry-Auth header to the /images/create endpoint. I think that's all that has to happen to make this work.
