Docker Hub is a cloud based repository that allows users to share container images.
Software developers use container images to automate software testing and deployment tasks.
Software developers can use public repositories to share their work.
https://hub.docker.com/u/haddley
The Docker playground allows users to run container images in a "playground" environment.
