DevOps for the Desperate introduces fundamental concepts software developers need to know to flourish in a modern DevOps environment including infrastructure as code, configuration management, security, containerization and orchestration, monitoring and alerting, and troubleshooting. Readers will follow along with hands-on examples to learn how to tackle common DevOps tasks.

The book begins with an exploration of DevOps concepts using Vagrant and Ansible to build systems with repeatable and predictable states, including configuring a host with user-based security. Next up is a crash course on containerization, orchestration, and delivery using Docker, Kubernetes, and a CI/CD pipeline. The book concludes with a primer in monitoring and alerting with tips for troubleshooting common host and application issues.

You'll learn how to:

  • Use Ansible to manage users and groups, and enforce complex passwords
  • Create a security policy for administrative permissions, and automate a host-based firewall
  • Get started with Docker to containerize applications, use Kubernetes for orchestration, and deploy code using a CI/CD pipeline
  • Build a monitoring stack, investigate common metric patterns, and trigger alerts
  • Troubleshoot and analyze common issues and errors found on hosts
