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
7087a6e79610   5c1778a60cf8   "/start.sh"   About a minute ago   Up About a minute   80/tcp, 0.0.0.0:8000->8000/tcp, :::8000->8000/tcp   fastapi-application

After the application starts, navigate to http://localhost:8000 in your web browser and you should see the following json response:

{
"message": "OK"
}

Stop and remove the containers

$ docker compose down
