The .devcontainer folder includes everything needed to boot the app and do development in a remote container.

The container setup includes:
 - A redis container for Kredis, ActionCable etc.
 - A database (SQLite, Postgres, MySQL or MariaDB)
 - A Headless chrome container for system tests
 - Active Storage configured to use the local disk and with preview features working

If any of these options are skipped in the app setup they will not be included in the container configuration.

These files can be skipped using the `--no-devcontainer` option.
