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.

Reviewing the module index

As discussed in the preceding section, Ansible provides thousands of modules to make it fast and easy to develop playbooks and run them across multiple host machines. How do you go about finding the right module to begin with, though, when there are so many? Fortunately, the Ansible documentation features a well-organized, categorized list of modules that you can consult to find your desired module this is available here:

Let's suppose you want to see whether there is a native Ansible module that can help you configure and manage your Amazon Web Services S3 buckets. That's a fairly precise, well-defined need, so let's approach this in a logical manner:
