You know, you're not really missing anything, we just don't connect the dots very well. Install CLI, run `fly launch` in a directory with a Dockerfile, and it should just work. Most of our users don't start with a Docker image though, they start with Phoenix. What you're seeing is a little bit of indecisiveness in how we target the docs.
Thanks! I'd rather run with a defined image, is there a way to do that? Here's the image: https://hub.docker.com/r/fusionauth/fusionauth-app/tags (supports ARM or x86). Edit: https://news.ycombinator.com/item?id=30019258 shows, I think, how to do that.
Edit the config so the `internal_port` is right for the app you're running, then `fly deploy -i fusionauth/fusionauth-app` and you should be good.
