DevOps for the Desperate A Hands-On Survival Guide

"DevOps for the Desperate is a short, approachable guided tour of a few core tools in the software operations toolkit.

Structured as a set of hands-on tutorials in topics like system administration basics, configuration tools like Ansible and Vagrant, and orchestration tools like Kubernetes, this book covers a lot of ground quickly. The focus is very much on the practical, rather than the philosophy of DevOps. Don't expect to use this as your sole reference on DevOps topics, but this is worthwhile as a gentle starting point for the absolute beginner to software operations."
