Error In Elasticsearch Service in EC2 Instance

[Debasis_Mallick]

HI Team,

When setting up an Elasticsearch cluster on an AWS EC2 instance, it's important to configure the elasticsearch.yml file correctly. When using the private IP of the EC2 instance, the service starts successfully. However, if you attempt to use the public IP, the service fails to launch and does not provide any specific error messages. My understanding is that we should be using the public IP for this configuration; please let me know if I am mistaken.

Thanks,
Debasis

What error you got? It should mention that it was not able to bind to the ip address.

I don't think this is correct, Elasticsearch needs to bind to an IP address that exists in the machine and as far as I know on cloud providers those external public IPs does not exist in the machine, they use some NAT so any request to the public IP is routed to the private IP of the VM.

You just need to bind to the private ip address or 0.0.0.0.
