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.

Configuring Ansible for Kubernetes

Ansible can communicate with Kubernetes clusters using the Kubernetes Python libraries or directly via the Kubernetes API, as shown in Figure 11.3:

Figure 11.3 – Communication between Ansible and Kubernetes

Ansible modules and plugins for managing Kubernetes are available in the kubernetes.core Ansible collection. (The Ansible Kubernetes collection was released as community.kubernetes prior to the release of kubernetes.core 1.1.) We will install, configure, and use the kubernetes.core collection in the following sections.

Python requirements

To communicate with the Kubernetes or OpenShift API, use the Python client for the OpenShift API (https://github.com/openshift/openshift-restclient-python) Python library. Before using any of the Kubernetes modules, you need to install the required Python libraries, as follows:

$ pip install openshift
$ pip install PyYAML
