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 Kubernetes clusters using Ansible

Deploying a Kubernetes cluster involves many steps, including preparing nodes, installing container runtime packages, and configuring networking. There are multiple methods we can use for deploying Kubernetes clusters within testing or production environments. The installation method for a Kubernetes cluster also depends on your requirements, whether you are using single-node clusters or multi-node clusters with HA or you require the option to scale the cluster whenever needed, for example.

Kubespray is a production-grade Kubernetes cluster deployment method that uses Ansible as its foundation for provisioning and orchestration. Using Kubespray, it is possible deploy a Kubernetes cluster on top of bare-metal servers, virtual machines, and private cloud or public cloud platforms (for example, AWS, GCE, Azure, and OpenStack).

Kubespray is highly customizable and you can configure the cluster with different Kubernetes components of your...
