Multiple scripts are supported. The container will search for all `*.sh` files inside the
`/cron-scripts` directory. To make supporting multiple scripts easier, you can also map a directory
on the host to the `/cron-scripts` directory in the container:
```yml
services:
cron:
image: rcdailey/nextcloud-cronjob
volumes:
- ./my-scripts:/cron-scripts:ro
```
As an optional safety measure, mount the directory or files as read-only (via the `:ro` at the end).
The container should not modify the files, but it doesn't hurt to be explicitly strict.
### Notes
* All cron task shell scripts run at the same interval defined by `NEXTCLOUD_CRON_MINUTE_INTERVAL`.
