Expected result

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

$ docker compose ps
NAME                COMMAND             SERVICE             STATUS              PORTS
flask-web-1         "python3 app.py"    web                 running             0.0.0.0:8000->8000/tcp

After the application starts, navigate to http://localhost:8000 in your web browser or run:

$ curl localhost:8000
Hello World!

Stop and remove the containers

$ docker compose down
