This works fine, as far as I can tell. Note that to sync from quay.io a username and token password must be specified in the repo details. This can be found on the quay.io user settings page.

Please let me know if there are any questions. Thanks!

Reopening... this works upstream but not in 6.3.0. Pulp is not able to find a registry at https://quay.io even w/ username/password.

I was able to get this to work with current master on pulp and pulp_docker. It is unclear if there is a bug or if the reproduction steps were incorrect.

1. I made a public repository on quay.io, https://quay.io/repository/asmacdo/busybox

2. Create a pulp repo

$ pulp-admin docker repo create --repo-id myquay --feed https://quay.io/repository/ --upstream-name asmacdo/busybox

3. Sync 

$ pulp-admin docker repo sync run --repo-id myquay

There could be an auth issue as well, but please make sure that the feed and upstream name are both correct.

@amacdona - Does it work in either of these versions?
pulp-server-2.13.4.6-1.el7sat.noarch.rpm 
pulp-server-2.13.4.9-1.el7sat.noarch.rpm

i did not look very deep in here but this looks like same issue with tokens and scope specification like in google registry.

as you can see the scope is not specified by registry in the auth-header

with this patch we in a defensive way are setting the scope even if the registry did not provide it:
