Overview of this book

Get ready to leverage the power of Ansible’s wide applicability to automate and manage IT infrastructure with Ansible for Real-Life Automation. This book will guide you in setting up and managing the free and open source automation tool and remote-managed nodes in the production and dev/staging environments. Starting with its installation and deployment, you’ll learn automation using simple use cases in your workplace. You’ll go beyond just Linux machines to use Ansible to automate Microsoft Windows machines, network devices, and private and public cloud platforms such as VMWare, AWS, and GCP. As you progress through the chapters, you’ll integrate Ansible into your DevOps workflow and deal with application container management and container platforms such as Kubernetes. This Ansible book also contains a detailed introduction to Red Hat Ansible Automation Platform to help you get up to speed with Red Hat AAP and integration with CI/CD and ITSM. What’s more, you’ll implement efficient automation solutions while learning best practices and methods to secure sensitive data using Ansible Vault and alternatives to automate non-supported platforms and operations using raw commands, command modules, and REST API calls. By the end of this book, you’ll be proficient in identifying and developing real-life automation use cases using Ansible.

Collaboration is the key to automation

Now you have your Ansible automation content in your GitHub repository. There are several advantages to this:

  • You do not need to take a backup of your files before you make changes (once you make the changes, remember to test, commit, and push the changes to a remote GitHub repository).
  • Pull the content to any of the machines whenever needed and test it. For example, you can download the code to your local workstation and develop it further. Once you make the changes, push it back to the remote repository; a new version of the code will be stored there.
  • Other users and developers can test and contribute to your code without having access to your Ansible control node. You just need to allow appropriate access to other users.
  • If any of the code is not working after an update, you can revert to an old version of the code at any point in time.

Let’s learn how to use Git branching in the next session.
