I just found this in Heroku's container docs:

Both Cedar-14 and Heroku-16 are available as Docker images. However, you are free to use any base image you want – using a Heroku stack image is not required.

I'm wondering if we can just use the bitwalker/alpine-erlang or something.

As an aside, if we use the Heroku image, we should consider switching to Heroku-16:

If you chose to use a Heroku image we suggest Heroku-16, given it is much smaller than Cedar-14 (465.3 MB).
