DevOps for the Desperate

If you’re a software engineer, developer, or sys admin who needs to get up to speed with DevOps quickly, this book covers the basics you need to thrive in a modern application stack.

This book’s fast-paced, hands-on examples will provide the foundation you need to start performing common DevOps tasks. You’ll explore how to implement Infrastructure as Code (IaC) and configuration management (CM)—essential practices for designing secure and stable systems. You’ll take a tour of containerization and set up an automated continuous delivery (CI/CD) pipeline that builds, tests, and deploys code. You’ll dig into how to detect a system’s state and alert on it when things go sideways.

You’ll learn how to:

Create and provision an Ubuntu VM with Vagrant and Ansible
Manage users, groups, and password security
Set up public key and two-factor authentication over SSH
Automate and test a host-based firewall
Use Docker to containerize applications and Kubernetes for orchestration
Build a monitoring stack and troubleshoot problems and performance issues
