# 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](http://en.wikipedia.org/wiki/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](https://hub.docker.com), 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](https://docs.docker.com/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](https://github.com/docker/docker-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
```

Simple as that? Yes. Now, please read the...
