To complete this exercise setup the following steps have been taken:

1. Initialize a repository and set up a remote on GitHub
2. Create the Dockerfile
3. Create the workflow.yml in a new .github/workflow folder
4. Set the right GitHub secrets for the DOCKER_USERNAME and DOCKER_PASSWORD values
5. Push to your remote GitHub and observe the workflow
6. Create the docker-compose.yml file (of course with your own Docker Hub account name to get the container from) and test the deployment by visiting localhost:8080 after the docker compose up command
7. Create the DishTest test file in the src/test/fact/it/examplemvc folder
8. See if the additional test runs in the workflow after a push
