New strapi deployment on fly.io seems to get reset

We recently deployed successfully (kind of ) on fly.io using this tutorial:
Fly.io Deployment - Strapi Developer Docs

We got to the super admin creation page successfully, but after creating a super admin, almost immediately, the super admin creation page showed up again. I got in for a while, but then it showed up again, and my previously-created logins didn’t seem to work. Has anyone seen this before?

I think the app was crashing due to low memory. I’ve updated to 2048MB per machine and so far it seems to be more stable.

Sometimes on these hosts they may not automatically configure a database for you and Strapi by default uses SQLite so unless you actually configure the database (and if they are using something like docker containers) when the app restarts it’s going to wipe all the data since the SQLite db file is deleted.
