Hi,

I configured a proxy for docker hub, the remote url is set to [https://docker.io](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!

Try proxying [https://registry-1.docker.io](https://registry-1.docker.io)

If that doesn’t work can you relay your Docker Index?

Tried again, It works by following the docs to set remote url to [https://registry-1.docker.io](https://registry-1.docker.io) and select Use Docker Hub

Thanks for your help!
