Hazelcast discovery on AWS

[rishav.s...@moonshinetechnology.com]

Getting " com.hazelcast.aws.AwsDiscoveryStrategy WARNING: No EC2 instances found!" after running my application on EC2 instance. I am running the application on 2 instances but they are not discovering each other. 

I have gone through the GitHub post related to the same issue but the correct hazelcast.xml config link is broken. Can someone please help?

Below is my Hazelcast.xml file :-

<aws enabled="true">

                <access-key>***************</access-key>

                <secret-key>***************</secret-key>

                <!--optional, default is us-east-1 -->

                <region>us-east-2</region>

                <!--optional, default is ec2.amazonaws.com. If set, region shouldn't be set as it will override this property -->

                <host-header>ec2.amazonaws.com</host-header>

                <!-- optional, only instances belonging to this group will be discovered, default will try all running instances -->

                <security-group-name>mySecurityGroup</security-group-name>

                <tag-key>myKey</tag-key>

                <tag-value>myValue</tag-value>

                <hz-port>5701-5718</hz-port>

            </aws>

            <interfaces enabled="true">

                <interface>172.31.*.*</interface>

            </interfaces>

The other discovery mechanisms are disabled.

My region value was incorrect. My EC2 instances were running in different regions but i had provided default region value i.e us-east-2. You can check the values you provided in hazelcast.xml. There might be something wrong. Also, try keeping only necessary tags like access-key, secret-key, region, SG name, port etc and remove the optional tags.
