Moby Project - a collaborative project by created docker for the container ecosystem to assemble container-based systems

Moby is an open-source project created by Docker to advance the software containerization movement. It provides a “Lego set” of dozens of components, the framework for assembling them into custom container-based systems, and a place for all container enthusiasts to experiment and exchange ideas.

At the core of Moby is a framework to assemble specialized container systems. It provides:

  • A library of containerized components for all vital aspects of a container system: OS, container runtime, orchestration, infrastructure management, networking, storage, security, build, image distribution, etc.
  • Tools to assemble the components into runnable artifacts for a variety of platforms and architectures: bare metal (both x86 and Arm); executables for Linux, Mac and Windows; VM images for popular cloud and virtualization providers.
  • A set of reference assemblies which can be used as-is, modified, or used as inspiration to create your own. All Moby components are containers, so creating new components is as easy as building a new OCI-compatible container.
