Chapter 5 running docker-compose up for the example-voting-app does not work correctly

While running the docker-compose up command for the docker-compose.yml file, the postgres container fails to start:

/>  docker-compose ps
              Name                            Command               State                       Ports

This maybe due to postgres complaining about a password not being present while setting up the postgres container.
