setting up local docker registry

Normally i thought this is going to be difficult process. But turns out to be easy as,

docker run -d -p 5000:5000 --restart=always --name registry registry:2

From this point onward, your registry is already setup. So it is just working with docker images by pulling, tagging and pushing it.

 docker tag ubuntu:16.04 localhost:5000/my-ubuntu

the only part you have to get it right is tagging with localhost:5000/

docker push localhost:5000/my-ubuntu

That's it, we're done. (your can try to browse your docker repo with a browser example, :- http://localhost:5000/v2/_catalog)


Testing it out 

Remove all our local images

$ docker image remove ubuntu:16.04
$ docker image remove localhost:5000/my-ubuntu

Lets try pulling it from our registry.

docker pull localhost:5000/my-ubuntu

That's ways easy.
