Environment:

- es 5.4.0 on docker
- aws ec2 cluster

==

Hi all,

I am trying to deploy a new cluser of es 5.4.0 on aws.  
I am using the same tf code and a similar docker image (I needed to change some minor details due to the centos migration) but the clauster fails to form.  
To be precise I can see the following WARN:

`[2017-05-05T13:10:32,470][WARN][o.e.d.c.s.Setting] [cloud.aws.region] setting was deprecated in Elasticsearch and will be removed in a future release! See the breaking changes documentation for the next major version.`

And after:

`[2017-05-05T13:10:32,473][INFO][o.e.d.DiscoveryModule] [xxx.ec2.internal] using discovery type [zen]`

I looked again at the the docs but I didn't find anything regarding cloud.aws.region deprecation.  
Not in this version:  
[https://www.elastic.co/guide/en/elasticsearch/plugins/5.4/discovery-ec2-discovery.html](https://www.elastic.co/guide/en/elasticsearch/plugins/5.4/discovery-ec2-discovery.html)  
or the next  
[https://www.elastic.co/guide/en/elasticsearch/plugins/5.x/discovery-ec2-discovery.html](https://www.elastic.co/guide/en/elasticsearch/plugins/5.x/discovery-ec2-discovery.html)

Anybody saw this error or has any idea on what is causing it?

Regards,  
F.

I agree that it's not super easy to find even though it's stated `See the breaking changes documentation for the next major version.`.

I believe that we should stop documenting the `region` field from 5.4 docs. I note that we are still documenting `region` in our master docs. [https://www.elastic.co/guide/en/elasticsearch/plugins/current/repository-s3-repository.html](https://www.elastic.co/guide/en/elasticsearch/plugins/current/repository-s3-repository.html)

But I know that @rjernst wants to clean that documentation after all the changes are made.

Thanks @jasontedor and @dadoonet.  
Sorry I missed that.  
I think updating the main ec2 plugin page will solve most of the problems 🙂
