Hi @MiTschMR, thanks for your reply. I thought that "--name" must be a mistake. However, I still feel like the blog post is more straight forward. I get very confused on the Elastic blog post. It is also using a two node setup. Well, than I will try it again I guess. One question ... It says:

```
dns: ['node1.elastic.test.com']

```

"node1" is the "node.name" configured in the yml-file, right? So, if my Elastic instance is hosted on [test.example.com](http://test.example.com), I would write:

```
instances:
  - name: 'node1'
    dns: ['node1.test.example.com']

```

And the kibana-part would be as follows?

```
- name: 'my-kibana'
    dns: ['kibana.local']

```

Where 'my-kibana' is set in the kibana.yml file under "server.name: my-kibana"? And dns must be specified as well (like [my-kibana.test.example.com](http://my-kibana.test.example.com)) or is it simply kibana.local as in the tutorial? Apologies if the questions are silly, I just got too confused already and don't understand fully.

Last but not least: **Any ideas how to integrate Let's encrypt**?

Thanks again for your time!
