I configured a proxy for docker hub, the remote url is set to https://docker.io. According to Pull Images of Nexus document, the following command does not works here:
docker pull :9090/ubuntu
I got :
Error response from daemon: manifest for :9090/ubuntu:latest not found
if I changed to (added library):
docker pull :9090/library/ubuntu
it works well.
That is, Nexus is not silently default to /library here if no namespace provided.
What is wrong with my configuration?
Nexus version: 3.15.2-01
Thanks for your help!
