Docker registry only accessible using core dns

[PawelJi]

I've installed docker registry on cluster, which could not be used to fetch images(builds and pushes from local to it works fine).

Issues:

1. Node on which is deployed could not resolve dns(dns is correct: docker-registry.abc.svc.cluster.local): probobly resolve.conf on node is incorrect
2. Failed to do request: Head "https://docker-registry... - I do no have tls/https over it, how could I use it for testing purposes without external access and secure protocol

What I'm missing?
What I did wrong ?
