I’m currently using sonatype nexus 3 as a repository for my docker images and it works from my coreos boxes:
core@ny-coreos-npd02 ~/.docker $ docker login registry.mywebsite.com
Username: admin
Password:
Email: admin@email.com
WARNING: login credentials saved in /home/core/.docker/config.json

core@ny-coreos-npd02 ~/.docker $ docker pull registry.mywebsite.com/nginx:1.9.12
1.9.12: Pulling from nginx

Status: Downloaded newer image for registry.mywebsite.com/nginx:1.9.12
However when I add the registry to Rancher 1.0.0 with the correct credentials. I get the following error when pulling
Error (500 Server Error: Internal Server Error (“Get https://registry.mywebsite.com/v2/nginx/manifests/1.9.12: no basic auth credentials”))
Is there somewhere else I need to set my credentials?
