As you can see [here](https://discuss.elastic.co/t/getting-aws-credentials-from-keystore-for-discovery-ec2-plugin/87958/5) David Pilato points out the documentation is not up to date.

> I see. Sadly the documentation has not been updated yet. It needs to be: discovery.ec2.access\_key discovery.ec2.secret\_key cloud.aws.region should not be used anymore but discovery.ec2.endpoint needs to be set in elasticsearch.yml file. See [https://github.com/elastic/elasticsearch/blob/5.4/plugins/discovery-ec2/src/main/java/org/elasticsearch/discovery/ec2/AwsEc2Service.java#L181-L188](https://github.com/elastic/elasticsearch/blob/5.4/plugins/discovery-ec2/src/main/java/org/elasticsearch/discovery/ec2/AwsEc2Service.java#L181-L188) I hope this helps. cc @rjernst in case I'm saying something wrong slight_smile

Sorry for make you upset, it wasn't my intention. I hope we can still be friends 🙂

This post going to help many people in the near future cos as you said there are not many ec2-discovery expert here, and if someone going to look for a solution with a similar problem whit any keywords which are in the title, they need to see a solution or any ideas regarding this problem.
