Docker Local Scheduler


Subcommands introduced in 0.12.12

scheduler-docker-local:report [<app>] [<flag>]              # Displays a scheduler-docker-local report for one or more apps
scheduler-docker-local:set <app> <key> (<value>)            # Set or clear a scheduler-docker-local property for an app


Introduced in 0.12.0

Dokku natively includes functionality to manage application lifecycles for a single server using the scheduler-docker-local plugin. It is the default scheduler, but as with all schedulers, it is set on a per-application basis. The scheduler can currently be overridden by running the following command:

dokku config:set node-js-app DOCKER_SCHEDULER=docker-local

As it is the default, unsetting the DOCKER_SCHEDULER config variable is also a valid way to reset the scheduler.

dokku config:unset node-js-app DOCKER_SCHEDULER


Disabling chown of persistent storage

The scheduler-docker-local plugin will ensure your storage mounts are owned by either herokuishuser or the overridden value you have set in DOKKU_APP_USER. You may disable this by running the following scheduler-docker-local:set command for your application:

dokku scheduler-docker-local:set node-js-app disable-chown true

Once set, you may re-enable it by setting a blank value for disable-chown:

dokku scheduler-docker-local:set node-js-app disable-chown
