Modern GitLab DevOps Handbook

Modern GitLab DevOps Handbook is a practical guide to designing and operating modern DevOps delivery pipelines using GitLab and the tools that commonly surround it.

Starting with Git and GitLab fundamentals, the book progressively moves into CI/CD, GitLab Runners, automated testing, Docker, container registries, DevSecOps, Kubernetes, Terraform, GitOps, release engineering, monitoring, troubleshooting, and enterprise DevOps practices.

A continuous project, DevOpsHub, connects the concepts and demonstrates how a real application can move from source code to a production-style environment.

Inside, readers will explore:

• Git and GitLab workflows
• Merge Requests and code collaboration
• GitLab CI/CD pipelines
• GitLab Runners
• Automated testing
• Docker and container registries
• DevSecOps practices
• Kubernetes deployment
• Terraform and Infrastructure as Code
• GitOps workflows
• Canary, rolling, and blue-green releases
• Monitoring and observability
• Production troubleshooting
• Incident response and recovery
• Enterprise GitLab practices
• Real-world DevOps interview scenarios
• Hands-on projects and challenges

The book focuses on practical understanding rather than memorizing isolated commands, helping readers build the knowledge needed to design, explain, troubleshoot, and improve modern DevOps environments.
