If what's meant here is that it would be hard to run this on a container platform because of the ephemeral nature of containers, assumably you would be using persistent volumes to keep your state safe across the container lifecycle.
That being said if you really wanted to use sqlite for the database, you'd do the exact same thing, use a persistent volume.
