You can set environment variables directly in your `fly.toml`.

You can't read secrets back once you've set them. That's because we can't read secrets back once we've set them --- at least, our API can't. The API has write-only access to our secret storage.

I'm fully aware of this but it doesn't help. I'd have to commit every change to variables into Git.

Environment is not code. And Heroku had it figured out.

And mind you, Fly.io is trying to sell itself as natural Heroku competitor.
