Create a remote private registry

Question

We are fairly new to docker but have been able to install docker on CentOS 6.4, created images, generated containers, and even created a private local registry.

Our question is in regards to the local registry. Well... actually... regarding a remote registry. We want to be able to create the registry on a separate server and not have everything in one place. We installed docker on another VM and have it running, but have had trouble finding documentation on how to access the registry remotely.

Just looking for some direction or url that will show how a remote registry would work.

Answer 1

Take a look at the Docker Registry repo - it's a separate project to docker.

Their README.md should be enough to get you started.

Answer 2

Our network would not allow us to access the internet to download RPMs. We determined the RPMs required to install docker-registry, downloaded them, placed them in a shell script in the order necessary to remove dependency issues, installed the RPMs and then start the service -- "service docker-registry start".

This does not create the registry as a docker image but as a standalone service -- not even sure why people seem to think having the registry as a docker image is preferable... seems to add an additional layer of unnecessary abstraction.

Below is the shell script with the list of RPMs in the "correct" order. Once executed, run "service docker-registry start".
