The Registry is a stateless, highly scalable server side application that stores and lets you distribute container images and other content.

This repository's main product is the Open Source Registry implementation for storing and distributing container images and other content 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.
