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.

Chapter 6: Infrastructure as Code (IaC) with Terraform

Cloud computing is one of the primary factors of DevOps' enablement today. The initial apprehensions that there were about the cloud are a thing of the past. With an army of security and compliance experts manning cloud platforms 24x7, organizations are now trusting the public cloud like never before. Along with cloud computing, another buzzword is taking the industry by storm – Infrastructure as Code (IaC). This chapter will focus on IaC with Terraform, and by the end of this chapter, you will understand the concept and have enough hands-on experience with Terraform to get you started in your journey.

In this chapter, we're going to cover the following main topics:

  • Introduction to IaC
  • Setting up Terraform and Azure providers
  • Understanding Terraform workflows and creating your first resource using Terraform
  • Terraform state and backends
  • Terraform workspaces
  • Terraform outputs, state...
