Some background Im using TCP client on Scala to connect to my elasticsearch container on docker but im having issues with the client not finding the configured nodes. Im used kitematic to setup the official docker image but have modified the elasticsearch.yml to see if any changes there could fix my problem ``` val logger = LoggerFactory.getLogger(Logger.ROOT_LOGGER_NAME) val settings = Settings .builder() .put("cluster.name", "elasticsearch") .put("client.transport.sniff", false) .build() lazy val client = TcpClient.transport(settings, ElasticsearchClientUri("localhost", 9300)) client.execute { indexInto("bank" / "account") fields ( "account_number" -> 1001, "balance" -> 400, "firstName" -> "Lorenzo", "lastName" -> "Prinsloo", "age" -> 23, "gender" -> "M", "address" -> "4 Durmonte Durbanville", "employer" -> "Full Facing", "email" -> "cmlprinsloo@gmail.com", "city" -> "Cape Town", "state" -> "Western Province" ) refresh RefreshPolicy.IMMEDIATE }.await val resp = client.execute { search("bank" / "account") query "Lorenzo" }.await println(resp) client.close() ``` Using netcat i could query and see my port was indeed open to connections ``` localhost [127.0.0.1] 9300 (vrace) open ``` But when i run my service i run into this exception Exception in thread "main" NoNodeAvailableException[None of the configured nodes are available: [{#transport#-1}{JJcLvuDWR5aJMHUjl6LsOw}{localhost}{127.0.0.1:9300}]] my container logs show that the service is booting up properly [2018-06-14T13:07:10,271][INFO][o.e.n.Node] [] initializing ...
