Hi @govargo. Thanks for your PR.

I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

@govargo I noticed we dont have documentation on our website for addons registitry
we have one here for building images:
https://minikube.sigs.k8s.io/docs/tasks/building/

would you feel comfortable adding a page for addons registery and explaining how it is different than docker-env ? and an example of using it ?

[govargo]

Hi @medyagh.

I noticed there are an documentations about registry addon.
https://minikube.sigs.k8s.io/docs/tasks/docker_registry/
https://minikube.sigs.k8s.io/docs/tasks/registry/insecure/

So I think we don't have to add documentations about registry & usage.
But I noticed there is a 404 link in Using the Docker daemon docker registry section.

I'll add commit to fix this link error.
