From the developer:
Docker Hub is a cloud-based registry service which allows you to link to code repositories, build your images and test them, stores manually pushed images, and links to Docker Cloud so you can deploy images to your hosts. It provides a centralized resource for container image discovery, distribution and change management, user and team collaboration, and workflow automation throughout the development pipeline.
You may want to check out more software for Mac, such as Docker Cloud, Docker Terminal or Simple Hub, which might be similar to Docker Hub.
