I have just this (which ironically won't work now cause docker hub is down)
services:
registry:
restart: always
image: registry:2
ports:
- 5000:5000
dns:
- 9.9.9.9
- 1.1.1.1
volumes:
- ../files/auth/registry.password:/auth/registry.password
- registry-data:/var/lib/registry
environment:
REGISTRY_STORAGE_DELETE_ENABLED: true
REGISTRY_HEALTH_STORAGEDRIVER_ENABLED: false
REGISTRY_HTTP_SECRET: ${REGISTRY_HTTP_SECRET}
REGISTRY_AUTH: htpasswd
REGISTRY_AUTH_HTPASSWD_REALM: Registry Realm
REGISTRY_AUTH_HTPASSWD_PATH: /auth/registry.password
# REGISTRY_PROXY_REMOTEURL: "https://registry-1.docker.io/"
volumes:
registry-data:
I don't even remember how and when I set it up. I think it might be this: https://github.com/distribution/distribution/releases/tag/v2.0.0
Recently somebody has created a frontend, which I bookmarked but didn't bother to set up: https://github.com/Joxit/docker-registry-ui
For your personal use, you don't need an enterprise setting. It's just a simple compose file that you run.
You can host a registry in pull through mode, so you still have all the images you use locally, but if it's not in your registry yet, it pulls it from docker hub or whatever.
The only pain point is that a single registry can't do both. So if you want to push your own docker images AND have a "cache" of stuff from docker hub, you need to run two registries in two different modes. And then juggle the url's.
