It is the expectation that a docker registry can always be served as a static file tree (pull only). vbHey, $ curl -XGET https://registry-1.docker.io/v2/library/node/manifests/latest <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN"> <title>404 Not Found</title> <h1>Not Found</h1> <p>The requested URL was not found on the server. If you entered the URL manually please check your spelling and try again.</p> $ curl -XGET -H"User-Agent: docker/1.6.0" https://registry-1.docker.io/v2/library/node/manifests/latest {"errors":[{"code":"UNAUTHORIZED","message":"access to the requested resource is not authorized","detail":[{"Type":"repository","Name":"library/node","Action":"pull"}]}]} I actually added a little clarification in my 5th patch: "User-Agent: do" /* otherwise we get load-balanced(!) to a V1 registyry */ (I got this information from Andy G.) The second request obviously fails due to the bearer token not being provided, but at least we can see that we're hitting the correct endpoint here. I think that this is the correct behavior, since the original systemd-pull workflow was to check the Hub first and obtain the token, which I'm simply following here, however the token is now obtained from a separate endpoint. The thing is that the argument is --dkr-index-url, so we're actually specifying the Hub URL here and there's no way to specify a registry alone. (the "mirror" registry is received in HTTP headers from the Hub) Sounds like a topic for another patch? I hope that the pull-only policy will be relaxed soon :) A lot of roundtrips ...
I understand they've done this on their hub, to route client versions < 1.6.0 which can not do the v2 api. There ought to be a way not no
require UA headers. Will see what I can do. vb
