dokku does a lot of things that docker-compose does not. One of the bigger ones is zero downtime deploys:

This has the added benefit of warming up the app before traffic ever hits it, something I was always surprised that even heroku didn't do (at least, the last time I used it ~6 years ago)

I see compose in production all the time - especially from folks that want compose support _in_ Dokku. I bought this up with the compose project manager a few months back. It seems like an interesting use case but it didn't seem like the Docker folks were... aware that this was how folks used docker compose? There is a project out there - Wowu/docker-rollout - that sort of provides this but it has some rough edges.

Disclaimer: I am the Dokku maintainer.

Interesting, how is compose meant to be used then? Just for building images and running local dev environments?

My understanding is that they are focused on the local development loop at the moment, especially with the acquisition of Tilt. That said, I don't work there so take this all with a grain of salt.
