## Unattended installation
In case you want to perform an unattended installation of dokku, this is made possible through [debconf](https://en.wikipedia.org/wiki/Debconf_%28software_package%29), which allows you to configure a package before installing it.
You can set any of the below options through the `debconf-set-selections` command, for example to enable vhost-based deployments:
```bash
echo "dokku dokku/vhost_enable boolean true" | debconf-set-selections
```
After setting the desired options, proceed with the installation as described above.
### debconf options
| Name | Type | Default | Description |
| ------------------ | ------- | --------------------- | ------------------------------------------------------------------------ |
| dokku/web_config | boolean | true | Use web-based config for below options |
| dokku/vhost_enable | boolean | false | Use vhost-based deployments (e.g. <app>.dokku.me) |
| dokku/hostname | string | dokku.me | Hostname, used as vhost domain and for showing app URL after deploy |
| dokku/key_file | string | /root/.ssh/id_rsa.pub | SSH key to add to the Dokku user (Will be ignored on `dpkg-reconfigure`) |
