Hi friends,

With the following **elasticsearch.yaml:**  
[cluster.name](http://cluster.name): \*\*\*  
[node.name](http://node.name): ${HOSTNAME}

```
cloud:
    aws:
        region: eu-west-1

discovery:
    type: ec2

network:
    host: _ec2

discovery.zen.minimum_master_nodes: 1
discovery.zen.ping_timeout: 10s

```

**Dockerfile** :  
FROM elasticsearch:5.0  
RUN /usr/share/elasticsearch/bin/elasticsearch-plugin install discovery-ec2  
COPY elasticsearch.yml /usr/share/elasticsearch/config/  
COPY log4j2.properties /usr/share/elasticsearch/config/  
USER elasticsearch

You are running in a Docker container, right?

If so, you can't assign the `_ec2_` address I think as the Docker network address is not the private IP address assigned by EC2.

I'm not a Docker user so can't tell more but this is my guess at least.

OK, it makes sense 🙂  
Using _site_ makes it works, standalone.

Then, to create a cluster, which elasticsearch.yml should be used to ensure master/slaves can join themselves using AWS/Docker?
