"Mastering Shell for DevOps" is all about giving DevOps, cloud, and Linux folks the know-how to automate and make their workflows more efficient with shell scripting. The book uses real-world examples and simple instructions to show how to automate tasks and move away from manual work in a DevOps environment. We start with the basics of shell scripting, so you can learn to write scripts that get the job done. It then moves on to version control with Git and GitHub, showing the importance of collaboration and code management in this context. The book then jumps into infrastructure provisioning and configuration management, showing you how to automate the setup of servers and services using tools like AWS CLI, Docker, and Kubernetes. As your skills grow, you'll learn to set up monitoring and logging tools, automate incident detection and resolution, and manage network traffic and load balancing. The book also helps you learn how to automate security tasks, including user access management, vulnerability scanning, patching, and compliance checks. By the end of the book, you'll have a whole toolkit of shell scripts that will help you work more efficiently, reliably, and securely in your DevOps practices.

Key Features

"Terraform for Developers" provides a comprehensive guide to mastering infrastructure as code with Terraform, intended for both beginners and experienced practitioners. The book starts by introducing foundational Terraform concepts like its architecture, setup on various cloud platforms, and the syntax of its configuration language HCL. This grounds the reader in core skills needed to author infrastructure code.

It then explores the full lifecycle of a Terraform project from state management, provisioning, networking, troubleshooting errors, and testing practices. Each phase is explained through practical examples relevant to real-world usage. Advanced skills like performance optimization, CI/CD integration, and modules are covered to take the reader from basic to expert.

The book finishes with sophisticated use cases like Kubernetes infrastructure automation and secrets management with HashiCorp Vault with elementary level demonstrations. The end result is a 360-degree education in Terraform - from installation to advanced usage across public clouds. Readers gain both theoretical foundations and hands-on skills transferred through practical examples. The book takes a holistic approach that equips practitioners to leverage Terraform in production environments.

[Note: Readers are advised not to misguide this book as a mastering book but does covers every possible task Terraform can perform.]

A collection of over seventy-five solution-focused recipes, "Ansible DevOps Cookbook" will show you how to use Ansible to fix problems, simplify operations, and boost the efficiency of your DevOps practices. Clear, step-by-step directions are provided for every recipe in this cookbook, covering everything from basic setup to advanced techniques. You should start by creating an efficient inventory system, configuring control and managed nodes, and setting up your Ansible environment. You can implement effective solutions such as handling more complex playbook techniques, such as working with variables, facts, conditionals, loops, and more. You will be skillful to organize playbooks and create reusable automation with Ansible roles. You can increase your automation capabilities by accessing community-driven content through Ansible Galaxy, which is explained in the book. When it comes to cloud integration, the book goes into great detail on how to automate deployments on AWS, Azure, and GCP. These recipes show how to use Ansible modules for managing and provisioning cloud infrastructure, so you can manage resources efficiently and ensure high availability and performance. Ansible, Jenkins, and GitLab are among the many of the tools covered in this book, which teaches you to automate the build, test, and deployment pipeline as part of continuous integration and continuous delivery. From playbook errors to inventory management issues, this cookbook has solutions to fix it all. Ansible Tower and AWX are implemented in the last chapters to automate enterprise-grade tasks, including job scheduling, monitoring, and role-based access control. This book's practical, real-world solutions will help you improve your DevOps practices and maximize the effectiveness of Ansible in your automation processes. Key Learnings
