Hi, I'm trying to use EC2 discovery with ES 6.1 and ES 6.2. It doesn't seem to work at all. I did of course install the plugin and add the neccessary config file, as well as adding the EC2 instance IAM role, but the log says it still uses "zen" discovery:

```
[2018-02-07T10:46:49,451][INFO][o.e.p.PluginsService] [esnode01] loaded plugin [discovery-ec2]
[2018-02-07T10:46:52,316][INFO][o.e.d.DiscoveryModule] [esnode01] using discovery type [zen]
[2018-02-07T10:46:53,032][INFO][o.e.n.Node] [esnode01] initialized
[2018-02-07T10:46:53,041][INFO][o.e.n.Node] [esnode01] starting ...

```

I've provided the **config** , **EC2 IAM role** and **logs** here: [https://gist.github.com/fredsted/e37d60948d9f765eef615b21eebc6bfd](https://gist.github.com/fredsted/e37d60948d9f765eef615b21eebc6bfd)

It looks like I needed to set the ec2 endpoint in `elasticsearch.yml`, and now it seemingly works.

```auto
discovery.ec2.endpoint: ec2.eu-central-1.amazonaws.com

```

I wonder if there is a bug in the autodetection here?

There is a bug in the documentation.
