Expected result

Listing containers must show three containers running and the port mapping as below:

$ docker compose ps
NAME                      IMAGE                   COMMAND                  SERVICE             CREATED             STATUS                    PORTS

After the application starts, navigate to http://localhost:80 in your web browser.

Stop and remove the containers

$ docker compose down
