I'm trying to install via podman compose in 3 machines on AWS EC2 ``` version: "3" services: es01: image: docker.elastic.co/elasticsearch/elasticsearch:7.12.0 container_name: es01 environment: - node.name=es01 - cluster.name=es-thaicom-cluster - discovery.seed_hosts=es02,es03 - cluster.initial_master_nodes=es01,es02,es03 - "ES_JAVA_OPTS=-Xms3g -Xmx3g" - index.codec=best_compression - network.host=127.0.0.1 - http.host=0.0.0.0 extra_hosts: - "es01:127.0.0.1" - "es02:172.31.25.120" - "es03:172.31.18.77" dns: - 127.0.0.53 ports: - 9200:9200 - 9300:9300 ``` But I got errors like ``` { "type": "server", "timestamp": "2021-04-27T09:17:10,150Z", "level": "WARN", "component": "o.e.d.HandshakingTransportAddressConnector", "cluster.name": "es-thaicom-cluster", "node.name": "es01", "message": "[connectToRemoteMasterNode[172.31.18.77:9300]] completed handshake with [{es03}{OJUZTeWBTNy5GBwJfzdGpA}{2g4EtF2ASICtc0h5bUv9-A}{10.0.2.100}{10.0.2.100:9300}{cdfhilmrstw}{ml.machine_memory=4124807168, ml.max_open_jobs=20, xpack.installed=true, ml.max_jvm_size=3221225472, transform.node=true}] but followup connection failed", "stacktrace": [ "org.elasticsearch.transport.ConnectTransportException: [es03][10.0.2.100:9300] handshake failed. unexpected remote node {es01}{c-2xngTRTuS2TEU01hXFGA}{qzEYacQCSRq8XH9jrSdI3w}{10.0.2.100}{10.0.2.100:9300}{cdfhilmrstw}{ml.machine_memory=4124807168, ml.max_open_jobs=20, xpack.installed=true, ml.max_jvm_size=3221225472, transform.node=true}", "at org.elasticsearch.transport.TransportService.lambda$connectionValidator$5(TransportService.java:417) ~[elasticsearch-7.12.0.jar:7.12.0]", "at org.elasticsearch.action.ActionListener$MappedActionListener.onResponse(ActionListener.java:70) [elasticsearch-7.12.0.jar:7.12.0]", "at org.elasticsearch.transport.TransportService$5.onResponse(TransportService.java:503) [elasticsearch-7.12.0.jar:7.12.0]", "at org.elasticsearch.transport.TransportService$5.onResponse(TransportService.java:493) [elasticsearch-7.12.0.jar:7.12.0]", "at org.elasticsearch.action.ActionListenerResponseHandler.handleResponse(ActionListenerResponseHandler.java:43) [elasticsearch-7.12.0.jar:7.12.0]", "at org.elasticsearch.transport.TransportService$ContextRestoreResponseHandler.handleResponse(TransportService.java:1280) [elasticsearch-7.12.0.jar:7.12.0]", "at org.elasticsearch.transport.TransportService$ContextRestoreResponseHandler.handleResponse(TransportService.java:1280) [elasticsearch-7.12.0.jar:7.12.0]", "at org.elasticsearch.transport.InboundHandler.doHandleResponse(InboundHandler.java:291) [elasticsearch-7.12.0.jar:7.12.0]", "at org.elasticsearch.transport.InboundHandler.lambda$handleResponse$1(InboundHandler.java:279) [elasticsearch-7.12.0.jar:7.12.0]", "at org.elasticsearch.common.util.concurrent.ThreadContext$ContextPreservingRunnable.run(ThreadContext.java:673) [elasticsearch-7.12.0.jar:7.12.0]", "at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1130) [?:?]", "at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:630) [?:?]", "at java.lang.Thread.run(Thread.java:832) [?:?]" ] } ``` How do I fix it? ---

That won't work, you need to give each node its own address. ---

I change environment - Remove `http.host` and `network.host`. - Add `network.publish_host=172.31.44.179`. It's work. ---

Although that might appear to work for now, I don't think it's the correct solution. See the [docs](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-network.html) on network settings, particularly for `network.publish_host`: > Use this setting only if binding to multiple addresses or using different addresses for publishing and binding. I don't think either of these apply to you, so you should just set `network.host`. ---
