# Distribution
|
|
|
|
The toolset to pack, ship, store, and deliver content.
|
|
|
|
This repository's main product is the Open Source Docker Registry implementation
|
|
for storing and distributing Docker and OCI images using the
|
|
[OCI Distribution Specification](https://github.com/opencontainers/distribution-spec).
|
|
The goal of this project is to provide a simple, secure, and scalable base
|
|
for building a registry solution or running a simple private registry.

This repository contains the following components:
|
|
|
|
|**Component** |Description |
|
|
|--------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
|
|
| **registry** | An implementation of the [OCI Distribution Specification](https://github.com/opencontainers/distribution-spec). |
|
|
| **libraries** | A rich set of libraries for interacting with distribution components. Please see [godoc](https://pkg.go.dev/github.com/distribution/distribution) for details. **Note**: The interfaces for these libraries are **unstable**. |
|
|
| **documentation** | Docker's full documentation set is available at [docs.docker.com](https://docs.docker.com). This repository [contains the subset](docs/) related just to the registry. |
|
|
|
|
### How does this integrate with Docker, containerd, and other OCI client?
|
|
|
|
Clients implement against the OCI specification and communicate with the
|
|
registry using HTTP. This project contains an client implementation which
|
|
is currently in use by Docker, however, it is deprecated for the
|
|
[implementation in containerd](https://github.com/containerd/containerd/tree/master/remotes/docker)
|
|
and will not support new features.
|
|
|
|
### 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.
|
|
|
|
### Who needs to deploy a registry?
|
|
|
|
By default, Docker users pull images from Docker's public registry instance.
|
|
[Installing Docker](https://docs.docker.com/engine/installation/) gives users this
|
|
ability. Users can also push images to a repository on Docker's public registry,
|
|
if they have a [Docker Hub](https://hub.docker.com/) 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](https://github.com/docker/docker.github.io/blob/master/registry/deploying.md)
|
|
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](https://github.com/docker/migrator).
