i'm trying to build up the 3-master 3-nodes elastic search stack in azure using vm. when i configure the elasticsearch with azure cloud discovery plugin i dont see that both master can communicate & it is not able to join the cluster. Elasticsearch version: 6.7.2 os: ubuntu 16.04 LTS what im trying to solve is, i wanted elasticsearch to discover new nodes and join to the cluster automatically. Please suggest how i can reslove this issue and implement node autodiscovery? my current elastic search.yml looks like below: cluster.name: "esprod" node.name: "master-3" path.logs: /var/log/elasticsearch path.data: /var/lib/elasticsearch discovery.zen.minimum\_master\_nodes: 2 node.master: true node.data: false network.host: 0.0.0.0 cloud: azure: management: subscription.id: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx cloud.service.name: esprod keystore: path: /etc/elasticsearch/azurekeystore.pkcs12 password: xxxxxxxxx discovery: zen.hosts\_provider: azure azure: host: type: private\_ip endpoint: name: elasticsearch i tested the pkcs12 which is fine.
