mrfusion already respects the PORT env var. No need to specify it.
After this commit, however, you will need to specify exposing the port
on the CLI when starting the container.
Heroku providers the PORT when it runs the container.

This probably breaks things running locally. Let's talk about how we can use the 8888 for local
development. Please refer to https://devcenter.heroku.com/articles/container-registry-and-runtime
for information.
NOTE: the EXPOSE keyword is not respected on heroku because they control the ports. Hence the
environment variable PORT.
