Containers come and go; data should not. Aeolus volumes and mounts keep databases, uploads, and config where you expect them after a restart.
Persistence basics
- Named volumes — attach durable storage to services that need it.
- Bind mounts — pin specific host paths when an ensemble requires them.
- Restart-safe data — bring an ensemble down and up without re-seeding the database by accident.
Operator tip
Declare mounts next to the service in the ensemble definition so the next person (or future you) can see what must survive a recreate.
