Ansible for Real-Life Automation

By: Gineesh Madapparambath

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.

Managing the container host

Various types of container software are available, such as Docker and Podman. In this chapter, we will be using Docker to explain and demonstrate container management using Ansible. We will be using Docker Community Edition (CE), which is free, though you can use Docker Enterprise Edition (EE) if needed.

Ansible Docker prerequisites

To use the Ansible Docker modules, you must install the docker library, which you can do using Python pip or standard packages managers such as yum (yum install python-docker-py) of dnf if available. If you are using the old version of Python (2.6), then you should install and use the old library called docker-py.

Installing Docker on the host using Ansible

Installing Docker software on a host involves multiple steps and configurations. These steps can be completed manually or we can use the Ansible role available in Ansible Galaxy. We will be using the community Ansible role called geerlingguy.docker (https://github...
