Authentication Required error when pushing image to private trusted registry

(Danoinct) #1

When I tag and attempt to upload my docker image to a private registry, I get the following error message:

root@localhost: docker push
4121acbcce4d: Preparing
84b2243fb072: Preparing

unauthorized: authentication required

The odd thing is that I can log into the registry server without issue, and I can push to my own project repository. Any idea what’s going on?

My docker client is version 1.12.6, running on CentOS 7.4.
The server is running 17.06.2, running on RHEL 7.4.
