Interplanetary Container Registry

tldr;

$ docker tag example/helloworld ipcr.io/helloworld:v1
$ docker push ipcr.io/helloworld:v1
...
$ docker pull ipcr.io/helloworld:v1

The toolset to pack, ship, store, and deliver container images over IPFS / Filecoin via Estuary.

This repository's main product is the Open Source Registry implementation for storing and distributing container images using the OCI Distribution Specification. The goal of this project is to provide a simple, secure, and scalable base for building a large scale registry solution or running a simple private registry. It is a core library for many registry operators including Docker Hub, GitHub Container Registry, GitLab Container Registry and DigitalOcean Container Registry, as well as the CNCF Harbor Project, and VMware Harbor Registry.

Build and Run IPCR registry

  1. Build the binary
$ make
  1. Setup Config file (config.yml)
version: 0.1
log:
  fields:
    service: registry

  1. Run the service
$ bin/registry serve config.yml

Configure

  • Create Dockerfile:

    FROM busybox:latest
    CMD echo 'hello world'
  • Build Docker image:

    $ docker build -t example/helloworld .

    Test run:

    $ docker run example/helloworld:latest
    hello world

    Tag and push

    $ docker tag example/helloworld ipcr.io/helloworld:v1
    $ docker push ipcr.io/helloworld:v1
    The push refers to repository [127.0.0.1:5005/helloworld]
    eb6b01329ebe: Pushed 
    v1: digest: sha256:8c061639004b9506a38e11fad10ce1a6270207e80c4a50858fa22cd2c115b955 size: 526
    
  • Pull image from IPCR registry

    $ docker pull ipcr.io/helloworld:v1
    v1: Pulling from helloworld
    Digest: sha256:8c061639004b9506a38e11fad10ce1a6270207e80c4a50858fa22cd2c115b955
    Status: Image is up to date for 127.0.0.1:5005/helloworld:v1
  • Run image pulled from IPCR:

    $ docker run ipcr.io/helloworld:v1
    hello world

Transferring images from dockerhub to registry

Included is a helper script to move all tagged images from dockerhub, quay.io, etc. to the IPCR decentralized registry.

Below is an example call to pull and transfer all tagged alpine images

$ script/migrateimages alpine 127.0.0.1:5005

Build Status GoDoc License: Apache-2.0 codecov FOSSA Status OCI Conformance

This repository contains the following components:

Component Description
registry An implementation of the OCI Distribution Specification.
libraries A rich set of libraries for interacting with distribution components. Please see godoc for details. Note: The interfaces for these libraries are unstable.
documentation Docker's full documentation set is available at docs.docker.com. This repository contains the subset 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 a client implementation which is currently in use by Docker, however, it is deprecated for the implementation in containerd 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.

Contribution

Please see CONTRIBUTING.md for details on how to contribute issues, fixes, and patches to this project. If you are contributing code, see the instructions for building a development environment.

Communication

For async communication and long running discussions please use issues and pull requests on the github repo. This will be the best place to discuss design and implementation.

For sync communication we have a #distribution channel in the CNCF Slack that everyone is welcome to join and chat about development.
