So, this chapter focuses on publishing images on the Docker Hub, and how to get the most out of the Docker Hub. We can create a new Docker image, using a commit command and a Dockerfile, build on it, and push it to the Docker Hub. The concept of a trusted repository will be discussed. This trusted repository is created from GitHub or Bitbucket. This can then be integrated with the Docker Hub to automatically build images, as a result of updates in the repository. This repository on GitHub is used to store the Dockerfile, which was previously created.
