I'm a newer to docker,and i want to use docker to deploy elasticsearch.
I follow the document step by step.And i can start a es instance successful.such as docker run -p 9208:9200 -p 9300:9300 -v /data/es1/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml docker.elastic.co/elasticsearch/elasticsearch:5.2.2.
But when i want to add the node to a exist cluster,and add a config discovery.zen.ping.unicast.hosts: ["xxx1:9300","xxx2:9300","xxx3:9300"] in /data/es1/elasticsearch.yml,but it throws an exception:
failed to send join request to master [{es130-data}{FwWjvb52RzGRP2IRa15DeA}{owS9GmMXTAqn0kioUtGmtw}{xxx}{xxx:9301}{box_type=warm, master=false}], reason [RemoteTransportException[[es130-data][xxx:9301][internal:discovery/zen/join]]; nested: ConnectTransportException[[ddFr9ut][172.17.0.2:9300] connect_timeout[30s]]; nested: IOException[No route to host: 172.17.0.2/172.17.0.2:9300]; ]
Here are my all configs:
cluster.name: skynet
cluster.routing.allocation.same_shard.host: true
node.attr.box_type: warm
node.attr.master: true
node.data: true
discovery.zen.ping.unicast.hosts: ["xxx1:9300","xxx2:9300","xxx3:9300"]
network.host: [_site_,_local_]
