Docker CE on premises with private repository: possible?

Question

I am wondering if it is possible to setup Docker CE on premises with a private repository (using DTR engine or other alternative if they exist)? My company has some strict rules to not have things in the cloud...

I know this is possible with the EE version but I would like to start with the CE version for a few months to see if it will work in our environment.

Answer 1

There are two parts to your question:

• deploying a registry itself
• configuring docker engine instances to access the registry

For deploying the registry all you need to do is deploy it as answered by @sony vizio and outlined here https://docs.docker.com/registry/deploying/#run-a-local-registry

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

For configuring your docker engines to access this registry you will need to add insecture-registries to /etc/docker/daemon.json (provided the above deployment took place on host registry):

{
  "insecure-registries": ["registry:5000"]
}

Images that you push to your local registry will need to be tagged with the registry host:port:

docker tag myimage registry:5000/myimage
docker push registry:5000/myimage

and then elsewhere

docker run registry:5000/myimage

Answer 2

I think what you are looking for is something like

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

docker reg server
