Expected result

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

$ docker ps
CONTAINER ID        IMAGE                        COMMAND                  CREATED             STATUS              PORTS                  NAMES

After the application starts, navigate to http://localhost:5000 in your web browser or run:

$ curl localhost:5000
Hello World!

Stop and remove the containers

$ docker-compose down
