3. Managing Your Docker Images
Overview
In this chapter, we will look into Docker layers and analyze how caching can help to speed up an image build. We will also deep dive into Docker images and set up Docker registries to increase the reusability of the images.
By the end of this chapter, you will be able to demonstrate how Docker uses layers to build images and how image building can be sped up with caching. You will work with image tags and set up a tagging policy for Docker images. The chapter will enable you to utilize Docker Hub for your projects and differentiate between public and private registries. It will also help you to set up your own Docker Registry when working on your projects.
