The DevOps 2.3 Toolkit

By: Viktor Farcic

Overview of this book

Building on The DevOps 2.0 Toolkit, The DevOps 2.1 Toolkit: Docker Swarm, and The DevOps 2.2 Toolkit: Self-Sufficient Docker Clusters, Viktor Farcic brings his latest exploration of the DevOps Toolkit as he takes you on a journey to explore the features of Kubernetes. The DevOps 2.3 Toolkit: Kubernetes is a book in the series that helps you build a full DevOps Toolkit. This book in the series looks at Kubernetes, the tool designed to, among other roles, make it easier in the creation and deployment of highly available and fault-tolerant applications at scale, with zero downtime. Within this book, Viktor will cover a wide range of emerging topics, including what exactly Kubernetes is, how to use both first and third-party add-ons for projects, and how to get the skills to be able to call yourself a “Kubernetes ninja.” Work with Viktor and dive into the creation and exploration of Kubernetes with a series of hands-on guides.

We'll start by deciding the name of our soon to be created cluster. We'll choose to call it devops23.k8s.local. The latter part of the name (.k8s.local) is mandatory if we do not have a DNS at hand. It's a naming convention kops uses to decide whether to create a gossip-based cluster or to rely on a publicly available domain. If this would be a "real" production cluster, you would probably have a DNS for it. However, since I cannot be sure whether you do have one for the exercises in this book, we'll play it safe, and proceed with the gossip mode.

We'll store the name into an environment variable so that it is easily accessible.

export NAME=devops23.k8s.local  

When we create the cluster, kops will store its state in a location we're about to configure. If you used Terraform, you'll notice that kops...
