feat: allow passing labels to one-off dokku containers

Browse Source

Finally, you may wish to run a container in "detached" mode via the `--detach` Dokku flag. Running a process in detached mode will immediately return a `CONTAINER_ID`. It is up to the user to then further manage this container in whatever manner they see fit, as Dokku will *not* automatically terminate the container.
