DevOps for Java Developers: From Code to Production

The book "DevOps for Java Developers" is a practical guide that will help Java programmers master key DevOps practices and tools. You will learn how to automate the build, testing, deployment, and monitoring of Java applications to accelerate time-to-market and increase reliability.

The book is aimed at Java developers of any level — from juniors to seniors — who want to expand their skill set and understand how modern infrastructure works. Basic knowledge of Java and a general understanding of Unix systems are sufficient. The book does not require administration experience or deep knowledge of networks.

What you will learn:

• How to set up a CI/CD pipeline with Jenkins, GitLab CI, and GitHub Actions for Java projects (Maven/Gradle).
• How to containerize Spring Boot applications using Docker and optimize images.
• Basics of orchestration with Kubernetes: deployment, services, configurations, scaling.
• Integration of monitoring and logging: Prometheus, Grafana, ELK stack for Java applications.
• Managing configurations and secrets (Helm, Vault, ConfigMaps).
• Principles of Infrastructure as Code (Terraform, Ansible) for deployment automation.
• Infrastructure testing and zero-downtime deployment strategies.

Book features:

• All examples are based on real Java projects (Spring Boot, Hibernate, Kafka).
• Step-by-step instructions and ready-to-use configuration files.
• Analysis of common mistakes and best practices from experienced DevOps engineers.
• Exercises at the end of each chapter to reinforce the material.

This book will be your guide to the world of DevOps. You will stop fearing terms like "containerization," "orchestration," and "pipeline," and will be able to independently build processes that save hours of manual work and make your code more stable in production.

Perfect for those who want to move from writing code to the full software development and delivery cycle, as well as for teams adopting DevOps culture in the Java ecosystem.
