Docker Registry
What it is
The Registry is a stateless, highly scalable server side application that stores and lets you distribute Docker images. The Registry is open-source, under the permissive Apache license.
Why use it
You should use the Registry if you want to:
- tightly control where your images are being stored
- fully own your images distribution pipeline
- integrate images storage and distribution into your inhouse development workflow
Alternatives
Users looking for a zero maintenance, ready-to-go solution are encouraged to head-over to the Docker Hub, which provides a free-to-use, hosted Registry, plus additional features (organization accounts, automated builds, and more).
Users looking for a commercially supported version of the Registry should look into Docker Hub Enterprise.
Requirements
The Registry is compatible with Docker engine version 1.6.0 or higher. If you really need to work with older Docker versions, you should look into the old python registry
TL;DR
# Start your registry
docker run -d -p 5000:5000 registry:2
# Pull (or build) some image from the hub
docker pull ubuntu
# Tag the image so that it points to your registry
docker tag ubuntu localhost:5000/myfirstimage
# Push it
docker push localhost:5000/myfirstimage
# Pull it back
docker pull localhost:5000/myfirstimage
