Hi, using the elasticsearch docker image `docker.elastic.co/elasticsearch/elasticsearch:6.1.2` I can't connect two nodes on different digitalocean droplets. I've created both containers with: droplet1: `docker run -d -p 9200:9200 -p 9300:9300 --name es1 -h es-asm-1 -v /opt/esdata1:/usr/share/elasticsearch/data -e "cluster.name=btwaf" -e "bootstrap.memory_lock=true" -e "ES_JAVA_OPTS=-Xms512m -Xmx512m" -e "network.host=0.0.0.0" -e "network.bind_host=0.0.0.0" -e "network.publish_host=0.0.0.0" -e "transport.host=0.0.0.0" --ulimit memlock=-1:-1 docker.elastic.co/elasticsearch/elasticsearch:6.1.2` droplet2: `docker run -d -p 9200:9200 -p 9300:9300 --name es1 -h es-asm-2 -v /opt/esdata1:/usr/share/elasticsearch/data -e "cluster.name=mycluster" -e "bootstrap.memory_lock=true" -e "ES_JAVA_OPTS=-Xms512m -Xmx512m" -e "discovery.zen.ping.unicast.hosts=droplet1:9300" -e "network.host=0.0.0.0" -e "network.bind_host=0.0.0.0" -e "network.publish_host=0.0.0.0" -e "transport.host=0.0.0.0" --ulimit memlock=-1:-1 docker.elastic.co/elasticsearch/elasticsearch:6.1.2` but on the second node I get this error: `org.elasticsearch.transport.ConnectTransportException: [Bs4USmT][172.17.0.2:9300] handshake failed. unexpected remote node` any idea? thanks ---

`network.publish_host=0.0.0.0` should be the address that you expect other nodes to use for communication. `discovery.zen.ping.unicast.hosts` says try talking to one of these hosts to find an elasticsearch cluster. The node it talks to then provides the cluster state, which would contain a list of all the nodes in the cluster + the the address (publish\_host) that should be used to establish communication with each of those nodes. `network.bind_host` = the interfaces that you want elasticsearch available on `network.host` = a shortcut for setting both `bind_host` and `publish_host` [https://www.elastic.co/guide/en/elasticsearch/reference/6.1/modules-network.html#common-network-settings](https://www.elastic.co/guide/en/elasticsearch/reference/6.1/modules-network.html#common-network-settings) ---

Did you ever get a solution for this? I can see the answer from Jared is useful, but not sure if this solves the problem. I'm facing a similar issue for which I've posted a separate question. ---
