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, on premises 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
docker pull ubuntu

# Name the image to point to your registry
docker tag ubuntu localhost:5000/myfirstimage

# Push it
docker push localhost:5000/myfirstimage

# Pull it
docker pull localhost:5000/myfirstimage
