Mastering Docker - Third 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 an impact on the world of web development. But how can you make sure you're keeping up with the innovations it's driving, or be sure you're using it to its full potential? Mastering Docker shows you how; this book not only demonstrates how to use Docker more effectively, but also helps you rethink and reimagine what's possible with it. You will cover concepts such as building, managing, and storing images, along with best practices to make you confident, before delving more into Docker security. You'll find everything related to extending and integrating Docker in new and innovative ways. Docker Compose, Docker Swarm, and Kubernetes will help you take control of your containers in an efficient manner. By the end of the book, you will 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.

In this chapter, we have taken a look at how we can deploy Docker Swarm clusters into a cloud provider using the tools provided by Docker themselves. We have also taken a look at two of the services offered by public clouds to run containers away from the core Docker toolset.

Finally, we looked at launching Kubernetes clusters in various clouds and running the same demo application in all of them. While it was clear from any of the commands we ran, all three of the public clouds were using various versions of Docker as the container engine. Though this could be subject to change by the time you read this, as in theory, they could switch to another engine with little impact.

In the next chapter, we are going to move back to working Docker and take a look at Portainer, a web-based interface for managing your Docker installation.
