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.

Imagine you’re a passionate chef dedicated to creating mouthwatering dishes that satisfy hungry customers. In your kitchen, which is a magical place called Docker, you have special powers to plan, make, and showcase your culinary creations. Let’s break down the key parts:

Ingredients (Application Code and Dependencies): Imagine your kitchen has shelves filled with ingredients such as flour, eggs, and spices. These ingredients come together in a specific way to make a dish. Similarly, your application code and dependencies work together to build your application.

Recipe (Image): Each recipe is like a plan for a particular dish. Imagine having a recipe for chocolate cake or pasta carbonara. These recipes are like the building blocks for your creations. In the same way, a Docker image is a plan for making your Docker container.

Recipe Cards (Dockerfile): Your cooking journey involves using special recipe cards called Dockerfiles. These cards...
