Docker, Inc. is the commercial entity behind the open source Docker project, and is the chief sponsor of the Docker ecosystem. Docker is an open source engine for deploying any application as a lightweight, portable, self-sufficient container that will run virtually anywhere. By delivering on the twin promises 'Build Once Run Anywhere' and 'Configure Once Run Anything,' Docker has seen explosive growth, and its impact is being seen across devops, PaaS and hybrid cloud environments. Nine months after launching, the Docker community is expanding rapidly: Docker containers have been downloaded over 400,000 times, the project has received almost 9,000 Github stars, and is receiving contributions from more than 300 community developers. Thousands of 'Dockerized' applications are now available at the Docker public index, and there are Docker meetup groups in over 30 countries around the world. Docker, Inc. offers both commercial Docker services and PaaS offerings at the docker.com website.
