# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.

# SQLite3 write its data on the local filesystem, as such it requires
# persistent disks. If you are deploying to a managed service, you should
# make sure it provides disk persistence, as many don't.
#
# Similarly, if you deploy your application as a Docker container, you must
# ensure the database is located in a persisted volume.
production:
  <<: *default
  # database: path/to/persistent/storage/production.sqlite3
