10 best practices to build a Java container with Docker

This cheat sheet provides best practices for building a production-grade Java container using Docker. The guidelines focus on creating an optimized, secure Java container for applications. Key points include using explicit and deterministic Docker base image tags, only installing necessary components in the Java container image, finding and fixing security vulnerabilities, using multi-stage builds to reduce image size, not running Java apps as root, properly handling events to safely terminate a Java application, gracefully tearing down Java applications, keeping unnecessary files out of container images with .dockerignore, ensuring Java is container-aware, and being cautious when using automatic Docker container generation tools.
