Please let me know in the replies what you'd like to see at Fly that would make it as good, if not better, than Heroku. I recently started working at Fly to focus on making Rails & Ruby app deployments awesome, and of course Heroku set that benchmark almost a decade ago. I can't promise I'll get to everything, but I can promise that it will help me better prioritize what I should be focusing on to make Fly better for…
I have a production rails app that I've been thinking of migrating to Fly from Heroku. After reading the Turboku[0] docs, it seems that the process only migrates the rails app itself, and continues to connect to the Postgres database on Heroku. Is that right? Are there any plans to "upgrade" Turboku or release a similar tool that makes migrating Heroku Postgres databases to Fly just as easy?
1. A doc will appear at https://fly.io/docs/rails/ that walks through how to move over a Heroku app, including the database. I'm going to start drafting this next week since I have a few SaaS apps running on Heroku that I want to move over.
2. If the docs are complicated and have lots of steps, I'll look into automating most of this process. I don't think I'll be able to 100% migrate Heroku apps to Fly without any intervention, but I do think moving over the app code, ENV vars, and database would be a pretty big win.
