# 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
```
