DevOps for Java Developers: A Practical Guide

The book "DevOps for Java Developers" is a practical guide that helps Java programmers master key DevOps practices and automate the processes of application development, testing, and deployment. The author, Alexey Smirnov, a senior engineer with 12 years of experience, shares real-world cases and solution templates that can be immediately applied in a project.

What is this book about?

The book covers the complete DevOps cycle for the Java ecosystem:

• Version Control Systems – advanced work with Git, branching strategies for Java projects (GitFlow, Trunk-Based).
• Build and Testing – configuring Maven and Gradle, automating unit and integration tests, static code analysis (SonarQube).
• CI/CD Pipelines – creating pipelines in Jenkins, GitLab CI, and GitHub Actions for Java applications.
• Containerization – Docker for Java: image optimization, multi-stage builds, working with JVM in containers.
• Orchestration – Kubernetes for Spring Boot microservices: deployment, scaling, configuration management.
• Monitoring and Logging – Prometheus, Grafana, ELK stack (Elasticsearch, Logstash, Kibana) for Java applications.
• Infrastructure as Code – Terraform and Ansible for environment management.

Who is this book for?

The publication will be useful for:

• Java developers of any level who want to implement DevOps practices in their projects.
• Team Leads and Architects planning a transition to a microservice architecture with automation.
• DevOps engineers looking to deepen their knowledge of the Java ecosystem specifics.
• Students and beginners who want to acquire in-demand skills at the intersection of development and operations.

What will the reader learn?

• How to set up automatic build and deployment of a Java project in 30 minutes.
• How to package a Spring Boot application in Docker and run it in Kubernetes.
• How to organize JVM performance monitoring in production.
• How to avoid common mistakes when implementing CI/CD.
• How to integrate security (SAST, DAST) into the pipeline.

All examples are accompanied by ready-made configuration files and scripts available in the repository. The book is written in a lively style, without excessive theory — only what actually works in production. It is an ideal tool for those who want to stop fearing DevOps and start using it to accelerate the delivery of high-quality Java code.
