DevOps for the Desperate: A Hands-On Survival Guide to Modern DevOps
DevOps for the Desperate is a practical, no-nonsense guide for software developers and technical professionals who need to quickly understand and work effectively in a modern DevOps environment.
Instead of focusing on abstract theory, the book takes a hands-on approach to the everyday technologies and challenges developers may encounter when working with DevOps. Readers learn through practical examples covering infrastructure automation, configuration management, security, containers, orchestration, software delivery, monitoring, alerting, and troubleshooting.
Build Repeatable Infrastructure
Start with DevOps fundamentals using Vagrant and Ansible to create systems with repeatable and predictable configurations. Learn how configuration management can help establish consistent environments and automate common administrative tasks.
Security & Configuration Management
Explore practical host security tasks, including managing users and groups, enforcing password requirements, creating administrative permission policies, and automating host-based firewall configuration.
Docker, Kubernetes & CI/CD
Learn the fundamentals of containerization with Docker, application orchestration with Kubernetes, and automated software delivery through a CI/CD pipeline. The practical workflow demonstrates how these technologies fit together in modern application environments.
Monitoring, Alerting & Troubleshooting
Build an understanding of monitoring and alerting by exploring common metrics, identifying important patterns, and responding to operational issues. The guide also provides practical direction for investigating common host and application problems.
