Hello,

You could save it in [secrets](https://fly.io/docs/reference/secrets/) and then get it in and out of your app with the necessary code for it.  
Secrets are made available via `env` variables to the app.  
There’s likely a size limit for any given secret, in the order of a few kilobyes or so.  
At least that’s what I remember reading a few days ago.

You could put it into `volumes` as well.
