Play with Docker (PWD) is a project hacked by Marcos Liljedhal and Jonathan Leibiusky and sponsored by Docker Inc.
PWD is a Docker playground which allows users to run Docker commands in a matter of seconds. It gives the experience of having a free Alpine Linux Virtual Machine in browser, where you can build and run Docker containers and even create clusters in Docker Swarm Mode.
