what if i wanted to run all 3 containers on the same app?
in my local development mode, all 3 containers run on their own port 3000.
i tied my host port 3000 to the reverse proxy container's port 3000
so now from my host, only reverse proxy is accessible, and i only needed one port to run 3 containers.
but in heroku, if i tie one container to the $PORT, what about the other 2 containers?
so i didnt want to run all the containers on the $PORT provided by heroku.

We're a place where coders share, stay up-to-date and grow their careers.
to make sure that your container and your app are using the same port to communicate with each other.actually, i wanted to run 3 containers on the same app -
i ultimately went on to make 3 separate heroku apps, one for each container, which works absolutely fine.
