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

$ docker ps

CONTAINER ID   IMAGE                  COMMAND                  CREATED              STATUS              PORTS                               NAMES

After the application start, navigate to http://localhost in your browser:

Stop and remove the containers
