Thanks @aman97,
I think the elasticsearch.yml settings needs to be updated to the below, I believe you are just missing the node.name setting in your config:
network.host: 0.0.0.0
node.name: node-1
discovery.seed_hosts: ["127.0.0.1"]
cluster.initial_master_nodes: ["node-1"]
Please try and let me know.
Thanks,
Liza
