Mastering Docker, Fourth Edition - Fourth Edition

Overview of this book

Docker has been a game changer when it comes to how modern applications are deployed and created. It has now grown into a key driver of innovation beyond system administration, with a significant impact on the world of web development. Mastering Docker shows you how you can ensure that you're keeping up with the innovations it's driving and be sure you're using it to its full potential. This fourth edition not only demonstrates how to use Docker more effectively but also helps you rethink and reimagine what you can achieve with it. You'll start by building, managing, and storing images along with exploring best practices for working with Docker confidently. Once you've got to grips with Docker security, the book covers essential concepts for extending and integrating Docker in new and innovative ways. You'll also learn how to take control of your containers efficiently using Docker Compose, Docker Swarm, and Kubernetes. By the end of this Docker book, you’ll have a broad yet detailed sense of what's possible with Docker and how seamlessly it fits in with a range of other platforms and tools.

Summary

In this chapter, we looked at several ways in which we can both manually and automatically build container images using Docker Hub. We discussed the various registries we can use besides Docker Hub, such as GitHub Packages and Microsoft's Azure Container Registry.

We also looked at deploying our own local Docker Registry and touched upon the considerations we need to make around storage when deploying one. Finally, we looked at MicroBadger, a service that allows us to display information about our remotely hosted container images.

All of this means you now have a way of distributing your own container images, both securely and in a way that allows you to easily keep your container images up to date.

This is important as it means that, if you wish, it is possible to trigger an update of all your images with a single build, rather than having to manually build and push each individual image.

In the next chapter, we are going to look at how to manage our containers...
