The fo You can always use a one-off container to run an app task: ```shell -dokku --rm run node-js-app some-command -dokku --rm-container run node-js-app some-command +dokku run node-js-app some-command ``` For tasks that should not be interrupted, run is the _preferred_ method of handling cron tasks, as the container will continue running even during a deploy or scaling event.
