Is it possible to connect nodes from internal network with node from external network through dynamic dns.
internal ip address:
node1 - 192.168.1.1
node2 - 192.168.2.2
public dns:
mypublic.ddns.net
Public dns resolves my public ip which is: 62.33.22.11
On my router configured port forwarding:
62.33.22.11:9301 -> 192.168.1.1:9301 (node1)
62.33.22.11:9302 -> 192.168.1.2:9302 (node2)
Node3 is external VPS and have public ip 88.77.55.44
My current config:
cluster.name: myclust
node.name: node-1
transport.host: 192.168.1.1
transport.port: 9301
network.host: 0.0.0.0
http.port: 9211
network.bind_host: 0.0.0.0
node.master: true
node.data: true
discovery.seed_hosts: ["mypublic.ddns.net:9301", "mypublic.ddns.net:9302", "88.77.55.44:9303"]
cluster.initial_master_nodes: ["node-1", "node-2", "node-3"]
cluster.name: myclust
node.name: node-2
transport.host: 192.168.1.2
transport.port: 9302
network.host: 0.0.0.0
http.port: 9222
network.bind_host: 0.0.0.0
node.master: true
node.data: true
discovery.seed_hosts: ["mypublic.ddns.net:9301", "mypublic.ddns.net:9302", "88.77.55.44:9303"]
cluster.initial_master_nodes: ["node-1", "node-2", "node-3"]
cluster.name: myclust
node.name: node-3
transport.host: 88.77.55.44
transport.port: 9302
network.host: 0.0.0.0
http.port: 9200
network.bind_host: 0.0.0.0
node.master: true
node.data: true
discovery.seed_hosts: ["mypublic.ddns.net:9301", "mypublic.ddns.net:9302", "88.77.55.44:9303"]
cluster.initial_master_nodes: ["node-1", "node-2", "node-3"]
Node1 and Node2 are joined with no problem which was in internal network, but on external Node3 i see in logs
master not discovered yet, this node has not previously joined a bootstrapped (v7+) cluster, and this node must discover master-eligible nodes [node-1, node-2, node-3]
If i using cluster.initial_master_nodes for all nodes like this:
cluster.initial_master_nodes: ["mypublic.ddns.net:9301", "mypublic.ddns.net:9302", "88.77.55.44:9303"]
I'm receiving on node3 such error:
