我采用官方文档中说明的，使用了docker-compose搭建了一个es集群。  
采用curl 方式访问都没有任何问题，使用elasticsearch-head工具监控也是正常的。  
但是使用Java编写代码链接集群出现异常，由于搭建es集群默认使用的是docker-compose中指定的网络链接方式，IP也是docker-compose自动分配的。与当前机器都不再同一个网段内，因此不知道怎么访问这个docker搭建的es集群？ 亲们有谁知道麻烦告知一下。 先谢谢啦。

docker-compose.yml 设置：

docker-compose.yml中使用的镜像都是从官方下载下来的，我重命名过。  
有知道怎么设置的亲们，帮忙给看看原因吧，谢谢啦~

最终我们采用jest通过9200端口操作es集群。 不知道这么做是不是合适~

你的配置文件里面貌似没有把9300也映射出来，所以连接失败，用http协议连接集群也是OK的。
