Overview of this book

The Linux DevOps Handbook is a comprehensive resource that caters to both novice and experienced professionals, ensuring a strong foundation in Linux. This book will help you understand how Linux serves as a cornerstone of DevOps, offering the flexibility, stability, and scalability essential for modern software development and operations. You’ll begin by covering Linux distributions, intermediate Linux concepts, and shell scripting to get to grips with automating tasks and streamlining workflows. You’ll then progress to mastering essential day-to-day tools for DevOps tasks. As you learn networking in Linux, you’ll be equipped with connection establishment and troubleshooting skills. You’ll also learn how to use Git for collaboration and efficient code management. The book guides you through Docker concepts for optimizing your DevOps workflows and moves on to advanced DevOps practices, such as monitoring, tracing, and distributed logging. You’ll work with Terraform and GitHub to implement continuous integration (CI)/continuous deployment (CD) pipelines and employ Atlantis for automated software delivery. Additionally, you’ll identify common DevOps pitfalls and strategies to avoid them. By the end of this book, you’ll have built a solid foundation in Linux fundamentals, practical tools, and advanced practices, all contributing to your enhanced Linux skills and successful DevOps implementation.

What is CI/CD?

CI/CD is a set of practices, tools, and processes that allow software development teams to automate the building, testing, and deployment of their applications, enabling them to release software more frequently and with greater confidence in its quality.

Continuous integration (CI) is a practice where developers regularly integrate their code changes into a repository, and each integration triggers an automated build and test process. This helps catch errors early and ensures that the application can be built and tested reliably.

For example, using Docker, a developer can set up a CI pipeline that automatically builds and tests their application whenever changes are pushed to the code repository. The pipeline can include steps to build a Docker image, run automated tests, and publish the image to a Docker registry.

Continuous delivery is the practice of getting software to be available for deployment after the successful integration process. For example, with...
