Docker Registry |
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.
You should use the Registry if you want to:
- tightly control where your images are being stored
- fully own your images distribution pipeline
- integrate image storage and distribution tightly into your in-house development workflow
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).
The Registry is compatible with Docker engine version 1.6.0 or higher.
Start your registry
docker run -d -p 5000:5000 --name registry registry:2
Pull (or build) some image from the hub
docker pull ubuntu
Tag the image so that it points to your registry
docker image tag ubuntu localhost:5000/myfirstimage
Push it
docker push localhost:5000/myfirstimage
Pull it back
docker pull localhost:5000/myfirstimage
Now stop your registry and remove all data
docker container stop registry && docker container rm -v registry
You should now read the detailed introduction about the registry, or jump directly to deployment instructions.
