The Docker toolset to pack, ship, store, and deliver content.

This repository's main product is the Docker Registry 2.0 implementation for storing and distributing Docker images. It supersedes the docker/docker-registry project with a new API design, focused around security and performance.

Circle CI GoDoc

This repository contains the following components:

Component Description
registry An implementation of the Docker Registry HTTP API V2 for use with docker 1.6+.
libraries A rich set of libraries for interacting with distribution components. Please see godoc for details. Note: These libraries are unstable.
specifications Distribution related specifications are available in docs/spec
documentation Docker's full documentation set is available at This repository contains the subset related just to the registry.

How does this integrate with Docker engine?

This project should provide an implementation to a V2 API for use in the Docker core project. The API should be embeddable and simplify the process of securely pulling and pushing content from docker daemons.

What are the long term goals of the Distribution project?

The Distribution project has the further long term goal of providing a secure tool chain for distributing content. The specifications, APIs and tools should be as useful with Docker as they are without.

Our goal is to design a professional grade and extensible content distribution system that allow users to:

  • Enjoy an efficient, secured and reliable way to store, manage, package and exchange content
  • Hack/roll their own on top of healthy open-source components
  • Implement their own home made solution through good specs, and solid extensions mechanism.

More about Registry 2.0

The new registry implementation provides the following benefits:

  • faster push and pull
  • new, more efficient implementation
  • simplified deployment
  • pluggable storage backend
  • webhook notifications

For information on upcoming functionality, please see

Who needs to deploy a registry?

By default, Docker users pull images from Docker's public registry instance. Installing Docker gives users this ability. Users can also push images to a repository on Docker's public registry, if they have a Docker Hub account.

For some users and even companies, this default behavior is sufficient. For others, it is not.

For example, users with their own software products may want to maintain a registry for private, company images. Also, you may wish to deploy your own image repository for images used to test or in continuous integration. For these use cases and others, deploying your own registry instance may be the better choice.

Migration to Registry 2.0

For those who have previously deployed their own registry based on the Registry 1.0 implementation and wish to deploy a Registry 2.0 while retaining images, data migration is required. A tool to assist with migration efforts has been created. For more information see docker/migrator.
