Need to setup a 3 node (D1, D2 & D3) docker cluster using swarm and install ElasticSearch & Kibana with each node on respective Oracle virtual Linux ( 7.4). D1 is Master node and D2, D3 worker nodes
Once docker engine is installed. Followed this document to create a swarm. https://docs.docker.com/engine/swarm/swarm-tutorial/create-swarm/
However , while executing the command on D2 or D3 gets below error:
Command: sudo docker swarm join --token <Token-ID> <IP>:2377
Error: Error response from daemon: rpc error: code = Unavailable desc = all SubConns are in TransientFailure, latest connection error: connection error: desc = "transport: Error while dialing dial tcp <IP>:2377: connect: no route to host"
All theses node servers are on the same network and no firewall restrictions. sudo netstat -tulpn | grep LISTEN shows ports 2377, 7946 are listening but don’t see port 4789 as mentioned here:https://docs.docker.com/engine/swarm/swarm-tutorial/
