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.

$ kubectl version

Next, we can run the following to see if kubectl can see our node:

$ kubectl get nodes

Now that we have our client interacting with our node, we can view the namespaces that are configured by default within Kubernetes by running the following command:

$ kubectl get namespaces

Then we can view the pods within a namespace with the following command:

$ kubectl get --namespace kube-system pods

Namespaces within Kubernetes are a great way of isolating...
