Hi, I try to connect one elasticsearch data node to another elasticsearch data-master node. Both elasticsearch are running in docker containers on two different virtual machines. When I try to connect I get error: [2018-06-01T12:21:19,083][WARN][o.e.d.z.ZenDiscovery] [elastic2] failed to connect to master [{elastic1}{Cs3L9TgtRBq5nlEnDn31IA}{Qr7ZvpCKTPaEx\_gZR2RJLw}{172.20.0.2}{172.20.0.2:9300}], retrying... org.elasticsearch.transport.ConnectTransportException: [elastic1][172.20.0.2:9300] handshake failed. unexpected remote node {elastic2}{efMUvUCBQIe3cezvDwPSwA}{t-zLPT8LQ7KGEepbyuTxtw}{172.20.0.2}{172.20.0.2:9300} at org.elasticsearch.transport.TransportService.lambda$connectToNode$3(TransportService.java:335) ~[elasticsearch-6.2.3.jar:6.2.3] at org.elasticsearch.transport.TcpTransport.connectToNode(TcpTransport.java:514) ~[elasticsearch-6.2.3.jar:6.2.3] at org.elasticsearch.transport.TransportService.connectToNode(TransportService.java:331) ~[elasticsearch-6.2.3.jar:6.2.3] at org.elasticsearch.transport.TransportService.connectToNode(TransportService.java:318) ~[elasticsearch-6.2.3.jar:6.2.3] at org.elasticsearch.discovery.zen.ZenDiscovery.joinElectedMaster(ZenDiscovery.java:515) [elasticsearch-6.2.3.jar:6.2.3] at org.elasticsearch.discovery.zen.ZenDiscovery.innerJoinCluster(ZenDiscovery.java:483) [elasticsearch-6.2.3.jar:6.2.3] at org.elasticsearch.discovery.zen.ZenDiscovery.access$2500(ZenDiscovery.java:90) [elasticsearch-6.2.3.jar:6.2.3] at org.elasticsearch.discovery.zen.ZenDiscovery$JoinThreadControl$1.run(ZenDiscovery.java:1253) [elasticsearch-6.2.3.jar:6.2.3] at org.elasticsearch.common.util.concurrent.ThreadContext$ContextPreservingRunnable.run(ThreadContext.java:573) [elasticsearch-6.2.3.jar:6.2.3] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) [?:1.8.0\_161] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) [?:1.8.0\_161] at java.lang.Thread.run(Thread.java:748) [?:1.8.0\_161] I attach configuration: ELASTICSEARCH DATA-MASTER: docker-compose: version: '2' services: elasticsearch: build: context: elasticsearch/ restart: always volumes: - ./elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml:ro #store data as docker volume (stored in /home/docker-data/volumes) - elastic\_search\_data:/usr/share/elasticsearch/data ports: - "9200:9200" - "9300:9300" environment: - cluster.name=elasticsearch-cluster - ES\_JAVA\_OPTS=-Xmx1024m -Xms1024m networks: - elk logstash: build: context: logstash/ restart: always volumes: - ./logstash/config/logstash.yml:/usr/share/logstash/config/logstash.yml:ro - ./logstash/pipeline:/usr/share/logstash/pipeline:ro - ./logstash/cert:/etc/pki/tls:ro - ./logstash/patterns:/usr/share/logstash/patterns:ro ports: - "5000:5000" environment: - LS\_JAVA\_OPTS=-Xmx512m -Xms512m networks: - elk depends\_on: - elasticsearch kibana: build: context: kibana/ restart: always volumes: - ./kibana/config/:/usr/share/kibana/config:ro ports: - "5601:5601" environment: - KI\_JAVA\_OPTS=-Xmx512m -Xms512m networks: - elk depends\_on: - elasticsearch volumes: elastic\_search\_data: driver: local networks: elk: driver: bridge elasticsearch.yml: cluster.name: elasticsearch-cluster network.host: 0.0.0.0 node.name: elastic1 node.master: true node.data: true discovery.zen.minimum\_master\_nodes: 1 discovery.zen.ping.unicast.hosts: ["172.28.4.185"] and second node: docker-compose: version: '2' services: elasticsearch: build: context: elasticsearch/ restart: always volumes: - ./elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml:ro #store data as docker volume (stored in /home/docker-data/volumes) - elastic\_search\_data:/usr/share/elasticsearch/data ports: - "9200:9200" - "9300:9300" environment: - cluster.name=elasticsearch-cluster - ES\_JAVA\_OPTS=-Xmx1024m -Xms1024m networks: - elk volumes: elastic\_search\_data: driver: local networks: elk: driver: bridge elasticsearch.yml: cluster.name: elasticsearch-cluster network.host: 0.0.0.0 node.name: elastic2 node.master: false node.data: true discovery.zen.minimum\_master\_nodes: 1 discovery.zen.ping.unicast.hosts: ["172.28.4.184"] Could anyone help me? ---

I`v found a solution for the issue. I`ve connected two docker services via docker network with type overlay. Overlay network allows to connect services running on different host machines. You can find how to configure overlay network in docker docs or in this video: [https://www.youtube.com/watch?v=nGSNULpHHZc](https://www.youtube.com/watch?v=nGSNULpHHZc) . I attach my current configuration: Elasticsearch data-master node: version: '3.6' services: elasticsearch-1: ... networks: - elasticsearch\_network logstash: ... networks: - elasticsearch\_network depends\_on: - elasticsearch-1 kibana: ... networks: - elasticsearch\_network depends\_on: - elasticsearch-1 networks: elasticsearch\_network: driver: overlay driver\_opts: encrypted: "true" elasticsearch.yml: cluster.name: elasticsearch-cluster network.host: 0.0.0.0 node.name: elasticsearch-1 node.master: true node.data: true discovery.zen.minimum\_master\_nodes: 1 discovery.zen.ping.unicast.hosts: [elasticsearch-2] Elasticsearch only data node: version: '3.6' services: elasticsearch-2: ... networks: - elk\_elasticsearch\_network networks: elk\_elasticsearch\_network: external: true driver: overlay elasticsearch.yml: cluster.name: elasticsearch-cluster network.host: 0.0.0.0 node.name: elasticsearch-2 node.master: false node.data: true discovery.zen.minimum\_master\_nodes: 1 discovery.zen.ping.unicast.hosts: [elasticsearch-1] ---

Thank you maciejgawlowski! It worked for me in my 2 aws machines, after I created the docker overlay network with docker-swarm. ---
