reference: implement Sort()
This upstreams `Sort()` as originally implemented in containerd in
https://github.com/containerd/containerd/0886ceaea2470edc7339dfc5ebe0e3257ae84d06

From that commit:

> Fix reference ordering in CRI image store
>
> Currently image references end up being stored in a
> random order due to the way maps are iterated through
> in Go. This leads to inconsistent identifiers being
> resolved when a single reference is needed to identify
> an image and the ordering of the references is used for
> the selection.
>
> Sort references in a consistent and ranked manner,
> from higher information formats to lower.
>
> Note: A `name + tag` reference is considered higher
> information than a `name + digest` reference since a
> registry may be used to resolve the digest from a
> `name + tag` reference.

Distribution

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

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 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.
