Docker and Testcontainers for Java Spring Boot Developers

Modern software development demands consistency from local coding to production deployment. For Java developers, containerization is a core skill for building reliable, scalable Spring Boot applications. This text-based course guides you through the process of containerizing Java applications from the ground up. You will transition from running applications locally to packaging them into optimized Docker images, orchestrating multi-container environments, and writing robust integration tests with Testcontainers. What you'll learn: - Understand containerization fundamentals and how Docker differs from traditional virtual machines. - Build optimized Docker images for Spring Boot applications using multi-stage builds and cloud-native buildpacks. - Configure multi-container environments using Docker Compose to manage databases and external services. - Apply Testcontainers in your Java test suite to run genuine integration tests against real databases. - Leverage Spring Boot's modern development-time Docker Compose integration for seamless local workflows. - Troubleshoot, debug, and manage running containers using essential command-line tools. The curriculum begins with core container concepts and command-line basics before moving step-by-step through image optimization, multi-service orchestration, and automated integration testing. You will learn through clear written explanations, structured configuration files, and practical Java code snippets. This course is designed for Java developers who are new to Docker and containerization. No prior experience with containers is required, though a basic understanding of Spring Boot is recommended.
