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.

Deploying Kubernetes using kind

The next tool we are going to look at is Kind, which is short for Kubernetes in Docker. This is exactly what you think it would be, based on the name – a Kubernetes cluster node condensed down into a container. Kind is a very recent project – so recent, in fact, that at the time of writing it is still undergoing a lot of active development. Because of this, we aren't going to spend too much time on it.

Installing Kind

Like Minikube, Kind is distributed as a single static binary – meaning its installation is very similar.

To install it on macOS, we need to run the following:

$ brew install kind

On Windows, run this:

$ choco install kind

Finally, on Linux, you can run the following:

$ KIND_VER=v0.8.1
$ curl -LO https://kind.sigs.k8s.io/dl/$KIND_VER/kind-$(uname)-
amd64
$sudo install kind-$(uname)-amd64 /usr/local/bin/kind
