I followed the instructions shown here for setting up Docker Hub as a proxy repository, but it appears to be stuck with the "Remote Connection Pending..." status. What am I missing?
I'm using Nexus 3 milestone 6. The Dockerfile I am using is here: https://github.com/baselibrary/docker-nexus/blob/801465b9593afcd1533acf020c529767096b223c/3.0/Dockerfile
The video instructions above are effectively the same as the ones listed in the documentation here: https://books.sonatype.com/nexus-book/3.0/reference/docker.html#docker-proxy
Your Nexus Repository Manager might be deployed behind a proxy server and it can therefore not connect to Docker Hub.
Have you tried to pull an image from the repository yet?
