This project can be packaged as a Java JAR and run inside a Docker container. Below are concise instructions for building the JAR, creating a Docker image, and running it.

Prerequisites:

• Docker installed and running
• A built JAR (for Maven: mvn -DskipTests package)

1. Example Dockerfile

FROM eclipse-temurin:17-jdk
ARG JAR_FILE=target/*.jar
COPY ${JAR_FILE} /app/app.jar
ENTRYPOINT ["java", "-jar", "/app/app.jar"]

2. Build the app (Maven example)

mvn -DskipTests package

3. Build the Docker image

docker build -t myapp:latest .

4. Run the container

docker run -d --name myapp -p 8080:8080 myapp:latest

Alternative: run without building an image (mount the JAR into an OpenJDK image)

docker run --rm -v "$(pwd)/target/your-app.jar:/app/app.jar" -p 8080:8080 eclipse-temurin:17-jdk java -jar /app/app.jar

Notes:

• Replace your-app.jar or target/*.jar with your actual built JAR filename.
• Adjust -p port mapping and environment variables as needed (use -e VAR=value).
• For Apple Silicon (M1/M2) you can use multi-arch base images or add --platform linux/amd64 to docker build/docker run if required.

Optional docker-compose (minimal)
