Modern DevOps Practices - Second Edition

By: Gaurav Agarwal

Overview of this book

DevOps and the cloud have changed how we look at software development and operations like never before, leading to the rapid growth of various DevOps tools, techniques, and practices. This updated edition helps you pick up the right tools by providing you with everything you need to get started with your DevOps journey. The book begins by introducing you to modern cloud-native architecture, and then teaches you about the architectural concepts needed to implement the modern way of application development. The next set of chapters helps you get familiarized with Git, Docker, Kubernetes, Ansible, Terraform, Packer, and other similar tools to enable you to build a base. As you advance, you’ll explore the core elements of cloud integration—AWS ECS, GKE, and other CaaS services. The chapters also discuss GitOps, continuous integration, and continuous delivery—GitHub actions, Jenkins, and Argo CD—to help you understand the essence of modern app delivery. Later, you’ll operate your container app in production using a service mesh and apply AI in DevOps. Throughout the book, you’ll discover best practices for automating and managing your development lifecycle, infrastructure, containers, and more. By the end of this DevOps book, you'll be well-equipped to develop and operate applications using modern tools and techniques.

Summary

This chapter covered Git, GitOps, why we need it, its principles, and various GitOps deployments. We also looked at different kinds of repositories that we can create to implement GitOps, along with the branching strategy choices for each of them.

You should now be able to do the following:

  • Understand what source code management is and how it is necessary for many activities with modern DevOps
  • Create a Git repository and play around with the clone, add, commit, push, pull, branch, and checkout commands
  • Understand what GitOps is and how it fits the modern DevOps context
  • Understand why we need GitOps and how it achieves modern DevOps
  • Understand the salient principles of GitOps
  • Understand how to use an effective branching strategy to implement GitOps based on the org structure and product type

In the next chapter, we will develop a core understanding of containers and look at Docker.
