Modern DevOps Practices

By: Gaurav Agarwal

Overview of this book

Containers have entirely changed how developers and end-users see applications as a whole. With this book, you'll learn all about containers, their architecture and benefits, and how to implement them within your development lifecycle. You'll discover how you can transition from the traditional world of virtual machines and adopt modern ways of using DevOps to ship a package of software continuously. Starting with a quick refresher on the core concepts of containers, you'll move on to study the architectural concepts to implement modern ways of application development. You'll cover topics around Docker, Kubernetes, Ansible, Terraform, Packer, and other similar tools that will help you to build a base. As you advance, the book covers the core elements of cloud integration (AWS ECS, GKE, and other CaaS services), continuous integration, and continuous delivery (GitHub actions, Jenkins, and Spinnaker) to help you understand the essence of container management and delivery. The later sections of the book will take you through container pipeline security and GitOps (Flux CD and Terraform). By the end of this DevOps book, you'll have learned best practices for automating your development lifecycle and making the most of containers, infrastructure automation, and CaaS, and be ready to develop applications using modern tools and techniques.

Installing Kubernetes (Minikube and KinD)

Let's now move on and install Kubernetes for your development environment. We will first begin with Minikube to get you started quickly, and then we will look into KinD. We will then use KinD for the rest of the chapter.

Installing Minikube

We will install Minikube in the same Linux machine we used to install Docker in Chapter 2, Containerization with Docker. So, if you haven't completed that, please go to Chapter 2, Containerization with Docker, and use the instructions to set up Docker on the machine.

We will first install kubectl. As described previously, kubectl is the command line utility that interacts with the Kubernetes API server. We will use kubectl multiple times in the book.

To download the latest release of kubectl, run the following command:

$ curl -LO "https://storage.googleapis.com/kubernetes-release/\
release/$(curl -s https://storage.googleapis.com/kubernetes-\
release/release/stable.txt)/bin...
