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.

Ansible community.postgresql prerequisites

If you are accessing PostgreSQL from a remote node (for example, an Ansible control node), then you need to install the psycopg2 Python library on this machine to use these PostgreSQL modules:

$ pip install psycopg2

In the next section, we will execute tasks from the database node itself (node1) using Ansible. This library is not required as the database server has already been configured with the required dependencies.

In the next section, you will learn how to manage database operations using Ansible and the community.postgresql collection.
