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.

Creating a Cluster

We'll continue using Minikube to simulate a cluster locally.

All the commands from this chapter are available in the 04-rs.sh (https://gist.github.com/vfarcic/f6588da3d1c8a82100a81709295d4a93) Gist.
minikube start --vm-driver=virtualbox
    
kubectl config current-context  

We created a single-node cluster and configured kubectl to use it.

Before we explore the first ReplicaSet example, we'll enter into the local copy of the vfarcic/k8s-spec repository and pull the latest version. Who knows, maybe I added some new stuff since the last time you checked it out.

cd k8s-specs
    
git pull  

Now that the cluster is running and the repository with the specs is up-to-date, we can create our first ReplicaSet.
