Learning DevOps - Second Edition

By: Mikael Krief

Overview of this book

In the implementation of DevOps processes, the choice of tools is crucial to the sustainability of projects and collaboration between developers and ops. This book presents the different patterns and tools for provisioning and configuring an infrastructure in the cloud, covering mostly open source tools with a large community contribution, such as Terraform, Ansible, and Packer, which are assets for automation. This DevOps book will show you how to containerize your applications with Docker and Kubernetes and walk you through the construction of DevOps pipelines in Jenkins as well as Azure pipelines before covering the tools and importance of testing. You'll find a complete chapter on DevOps practices and tooling for open source projects before getting to grips with security integration in DevOps using Inspec, Hashicorp Vault, and Azure Secure DevOps kit. You'll also learn about the reduction of downtime with blue-green deployment and feature flags techniques before finally covering common DevOps best practices for all your projects. By the end of this book, you'll have built a solid foundation in DevOps and developed the skills necessary to enhance a traditional software delivery process using modern software delivery tools and techniques.

Chapter 8: Deploying Infrastructure as Code with CI/CD Pipelines

In the first part of this book, we learned a lot about Infrastructure as Code (IaC), its advantages, and tools such as Terraform, Packer, and Ansible, and their command lines. Then, in the second part, we discussed Git and dedicated a chapter to the Continuous Integration and Continuous Deployment of applications.

However, we should not neglect to also put CI/CD into practice as IaC, which will allow us to orchestrate and automate the whole process of provisioning the infrastructure.

It is in this second edition of this book that I wanted to add this chapter to reuse all that we have learned in the previous chapters and show how to implement IaC with a CI/CD pipeline, which will be composed of Packer, Terraform, and Ansible.

The pipeline tool that will be used is Azure Pipelines, which we have already covered in detail in Chapter 7, Continuous Integration and Continuous Delivery. So we will learn how to write...
