Does anyone have a good tutorial on how to install multiple ES nodes on multiple EC2 instances?

I tried many tutorial and nothing works... each instance just assigned itself as master.  
(NOTE: my instances are in 2 zones: us-east-1a and us-east-1b)

Here is my ES configuration for AWS:

```auto
cluster.name: testcluster
cloud.aws.access_key: ***
cloud.aws.secret_key: ***
cloud.aws.region: us-east
discovery.type: ec2
discovery.ec2.tag.Name: "AWS Test Cluster"
http.cors.enabled: true
http.cors.allow-origin: "*"
discovery.ec2.tag.Environment: Staging
discovery.ec2.ping_timeout: 5s

```

It appears to just start working after some time ... not sure why/how.  
You can close this topic.
