Practical Ansible 2

By: Daniel Oh, James Freeman, Fabio Alessandro Locati

Overview of this book

Ansible enables you to automate software provisioning, configuration management, and application roll-outs, and can be used as a deployment and orchestration tool. While Ansible provides simple yet powerful features to automate multi-layer environments using agentless communication, it can also solve other critical IT challenges, such as ensuring continuous integration and continuous deployment (CI/CD) with zero downtime. In this book, you'll work with Ansible 2.9 and learn to solve complex issues quickly with the help of task-oriented scenarios. You'll start by installing and configuring Ansible on Linux and macOS to automate monotonous and repetitive IT tasks and get to grips with concepts such as playbooks, inventories, and network modules. As you progress, you'll gain insight into the YAML syntax and learn how to port between Ansible versions. In addition to this, you'll also understand how Ansible enables you to orchestrate multi-layer environments such as networks, containers, and the cloud. By the end of this Ansible book, you'll be well - versed in writing playbooks and other related Ansible code to overcome just about all of your IT challenges, from infrastructure-as-code provisioning to application deployments, and even handling the mundane day-to-day maintenance tasks that take up so much valuable time.

Coding Best Practices

Ansible can help you automate just about all of your daily IT tasks, from mundane tasks, such as applying patches or deploying configuration files, to deploying entirely new infrastructure as code. The use of, and engagement with, Ansible has been growing year by year as more and more people come to realize both its power and simplicity. You will find many example Ansible playbooks, roles, blog articles, and so on across the internet, and combined with resources such as this book, you will become proficient at writing your own Ansible playbooks.

Yet, how do you know what the best approaches for writing your automation code in Ansible are? How can you tell whether an example you found on the internet is actually a good way of doing things? In this chapter, we will take you through a practical guide of the best practices in Ansible, showing you what is currently...
