```

Letsencrypt can be completely disabled for a given app by setting the `letsencrypt-server` to `false`

```shell
dokku scheduler-k3s:set node-js-app letsencrypt-server false
```

The server can also be disabled globally, and then conditionally enabled on a per-app basis:

```shell
dokku scheduler-k3s:set --global letsencrypt-server false
```
