Available in Nexus Repository OSS and Nexus Repository Pro
Docker containers and their usage have revolutionized the way applications and the underlying operating system are packaged and deployed to development, testing and production systems.
The creation of the Open Container Initiative, and the involvement of a large number of stakeholders, guarantees that the ecosystem of tools around the lightweight containers and their usage will continue to flourish.
Nexus Repository Manager Pro and Nexus Repository Manager OSS support Docker registries as the Docker repository format for hosted and proxy repositories. You can expose these repositories to the client-side tools directly or as a repository group, which is a repository that merges and exposes the contents of multiple repositories in one convenient URL. This allows you to reduce time and bandwidth usage for accessing Docker images in a registry as well as share your images within your organization in a hosted repository. Users can then launch containers based on those images, resulting in a completely private Docker registry with all the features available in the repository manager.
Docker Manifest Lists NEW IN 3.22
Docker manifest lists allow a manifest to represent support for multiple architectures while maintaining a single "image:tag" reference format. See https://docs.docker.com/registry/spec/manifest-v2-2/ for more information on docker's schema specification.
The minimum version of Docker that works with Nexus Repository is version 1.8. But please note that Docker is a fast moving project and requires usage of current operating system versions and tools. For example, usage of Red Hat Enterprise Linux 6 is simply not supported. Please use the official documentation as reference and help for your usage.
