I setup registry with harbor 2.1, is there something import i miss?

I think what you're missing is that Harbor always includes a "project" name, and you are trying to push without that -- if you instead try something like 192.168.0.4:30003/library/ubuntu:18.04, it will probably work.

It is the root cause, seem harbor has no plan to support this: goharbor/harbor#10648
