Docker Hub

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.

Docker Hub provides the following major features:

Image Repositories: Find, manage, and push and pull images from community, official, and private image libraries. Automated Builds: Automatically create new images when you make changes to a source code repository. Webhooks: A feature of Automated Builds, Webhooks let you trigger actions after a successful push to a repository. Organizations: Create work groups to manage access to image repositories. GitHub and Bitbucket Integration: Add the Hub and your Docker Images to your current workflows.
