Java and Docker: Application Containerization

Modern Java development is impossible without understanding containerization. The book "Java and Docker: Application Containerization" is a practical guide that will take you step by step from creating your first Docker image for a simple Java application to deploying a full microservice architecture in a production environment.

What is this book about?

The book covers the complete lifecycle of working with Docker in the context of Java development. You will learn:

• How to properly create a Dockerfile for Spring Boot, Quarkus, Micronaut, and other popular frameworks.
• Principles of image optimization: multi-stage builds, size reduction, layer security.
• Working with Docker Compose for local development and testing of multi-container applications (databases, queues, caches).
• Integrating Docker with CI/CD pipelines (GitHub Actions, GitLab CI, Jenkins).
• Basics of orchestration with Kubernetes: deploying Java services, scaling, configuration management.
• Monitoring and logging of containerized applications (Prometheus, Grafana, ELK).

Who is this book for?

The publication will be useful for:

• Java developers of any level who want to master modern containerization practices.
• DevOps engineers seeking a deeper understanding of how Java applications work in Docker.
• Architects designing microservice systems in Java.
• Students and entry-level specialists striving to acquire in-demand skills for an IT career.

What will you learn after reading?

• Create efficient and secure Docker images for any Java application.
• Set up a local development environment with Docker Compose.
• Automate building, testing, and deployment using CI/CD.
• Deploy and manage Java services in Kubernetes.
• Avoid common containerization mistakes (memory issues, time zones, network settings).

The book contains numerous code examples, ready-made scripts, and checklists that can be immediately applied to real projects. All examples are available for download and testing. Dive into the world of Java application containerization with this book!
