Litestack problems with deployment

Questions / Help Build debugging

I’m trying to get a simple Rails app with Litestack deployed, but this part from the blog post doesn’t seem to work:

When the fly launch command is run, Fly.io runs the dockerfile-rails gem, which detects the Litestack gem and configures the Dockerfile with the VOLUME and ENV directives needed to store and access Sqlite databases on persistent volume.

The fly launch command then detects the VOLUME directives from the Dockerfile and adds them to the fly.toml file, which configures a persistent volume on the Fly Machine deployment target.

AFAICS, the only Litestack-specific thing that happens during fly launch is that ENV LITESTACK_DATA_PATH="/data" is added to the Dockerfile, but no “VOLUME and ENV directives needed to store and access Sqlite databases on persistent volume.”

Can anyone help out?
