Java Elasticsearch 客户端 : throws ConnectException when connecting from local to ES in Google Cloud VM

Question

我有一个在 google-compute-engine(VM) 中运行的 elasticsearch 集群，并且我正在尝试从我的 Java 程序进行连接。

谷歌云中的ES实例有一个外部IP和内部IP。我已经配置了用于连接的外部 IP，并且所有防火墙设置都已启用以进行连接。

仍然看起来，客户端在将 myd 数据写入 ES 时正在使用内部 IP。

10.240.0.237是内部IP

看起来您正在端口 9300 上进行连接，但我认为您需要端口 9200。
