Create a multi-stage Dockerfile for Spring Boot by separating build and runtime concerns to optimize caching. This pattern uses distinct build and runtime stages to produce production-ready images with reliable layering and shorter build times.

Tune JVM memory for Docker containers by applying flags like -Xmx and -XX:MaxRAMPercentage. This ensures container-aware heap allocation, optimizing performance and preventing out-of-memory errors in Spring Boot deployments.

Run a Spring Boot Docker image as a non-root user by specifying a secure runtime user in your Dockerfile. This container security pattern restricts privileges, reducing the attack surface of your production-ready images.

Docker Compose supports healthchecks for local Spring Boot development environments. You can configure dependencies and healthchecks to assemble a reliable local dev stack, ensuring services start correctly for rapid iteration.

Spring Boot Docker images have slow startup times and large layers due to poor caching and layering strategies. Applying multi-stage builds and optimized layering reduces image size and improves caching efficiency.

You need Docker Compose to scaffold a local development stack for Spring Boot. It provides guidance for assembling local dev environments, including healthchecks and dependencies, to enable rapid iteration.
