This is a simple example of how to use Docker to run a Javalin application.
The tutorial is available at https://javalin.io/tutorials/docker.
To run the example, you need to have Docker installed. You can download it from https://www.docker.com/products/docker-desktop.
First you need to package the application into a jar file. You can do this by running the package
goal in Maven:
mvn package
Then you can build the Docker image:
docker build -t javalin-docker-example .
Finally, you can run the Docker image:
docker run -p 7000:7000 javalin-docker-example
