Add Dockerhub automated build integration #866

[niccokunzmann]

As stated in issue #866 I want to be able to have a badge which shows the dockerhub build status.

Is this duplicate of #856

Thanks for this PR. It does look like it overlaps with #856.

I like your the way this handles the 404 / not found case.

Could you add that to your branch for #856 @eddiewebb?

The tag build feature would be a great addition, but unfortunately we can't have a badge that is "unbounded" in time or number of requests. To support the tag feature, we'd need them to add an API that allows accessing this information more directly.

@paulmelnikow added to #856, but checking for 404 which works for both invalid user and invalid repo (some reason docker hub returns valid JSON with invalid repo, but a html page for invalid user.

[eddiewebb]

agree on busy, new look just committed.

Since this will need to be reworked, and we're tracking that in #935, I'll close this.
