I have build an ES5.3 cluster with Kibana5.3 (No Logstash). I have my nodes in place and curl works just fine on all the nodes. But the problem is, the nodes are not discovering each other. I have tried several options but nothing worked. I am deploying this on EC2 instances.

My elasticsearch.yml file looks like this:

plugin.mandatory: cloud-aws  
[cluster.name](http://cluster.name): CC-ES-5.3-Cluster  
network.host:   
discovery.type: ec2  
discovery.zen.ping.multicast.enabled: false  
discovery.ec2.groups:   
cloud.aws.access\_key: \*\*\*\*\*  
cloud.aws.secret\_key: \*\*\*\*\*  
node.master: true  
node.data: false  
[node.name](http://node.name): es-master-02

What did I miss? Please help.

Thank you!

I doubt this line actually works:

```
plugin.mandatory: cloud-aws

```

What are the logs?

Hello dadoonet,

Here is where I am now with my cluster:  
I have built 3 master nodes and 6 data nodes on aws ec2 instances. I am unable to have my nodes discover each other. Is there any reference? I have looked at the documentation and followed the same but it doesn't seem to work. I am installing elasticsearch 5.3. Is it mandatory to have an ingest node? I feel that I dont need an ingest node for my use-case but is it made mandatory for 5.3?

Thank you in advance.
