Migrating to the Container registry from the Docker registry
An enterprise owner can migrate Docker images previously stored in the Docker registry on your GitHub Enterprise Server instance to the Container registry.
Working with the Container registry
You can store and manage Docker and OCI images in the Container registry, which uses the package namespace https://containers.HOSTNAME.
Working with the RubyGems registry
You can configure RubyGems to publish a package to GitHub Packages and to use packages stored on GitHub Packages as dependencies in a Ruby project with Bundler.
