Learning Ansible, Second Edition

There are thousands of reliable systems out there, and Ansible is the unsung hero that makes sure all your IT work is done on time and can be reviewed easily. This second edition shows you exactly the proven and usable, tried-and-tested ansible techniques that will help you bring stability to your own operation. It is a hands-on absolutely, built on Ansible-Core 2.21, where you'll set up a clean control node, write reusable roles, protect secrets and test each change before it reaches a server. Next, you'll be patching Linux and Windows fleets, provisioning AWS and Azure resources using Terraform, deploying to Kubernetes and OpenShift, and sharing automation safely through Ansible Automation Platform. In the later chapters, it's all about production. You'll build monitoring with Prometheus and Grafana, fix familiar failures automatically with Event-Driven Ansible, and diagnose CPU, memory, database and network faults with ready-to-run playbooks. At last, you'll be able to hook up AI agents and MCP servers to Ansible. Every single chapter is making a strong effort to focus on practical, hands-on techniques, so you can put each one into practice right away.
