java - 无法连接到docker中的elasticsearch容器

Question

我正在尝试使用 docker 的官方 elasticsearch 镜像，并且遵循了 this guide，但是当我尝试连接到 elasticsearch 集群时，出现了异常 NoNodeAvailableException[配置的节点均不可用

我的代码

TransportClient client = new PreBuiltTransportClient(Settings.builder().put("cluster.name", "docker-cluster")
                .build())
                .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("127.0.0.1"), 9300));

为了运行elasticsearch容器，我使用了这个命令

docker run -p 9200:9200 -p 9300:9300 -e "http.host=0.0.0.0" -e "transport.host=127.0.0.1" docker.elastic.co/elasticsearch/elasticsearch:5.2.2

当我在 localhost:9200 上打开浏览器时，浏览器会显示此文本

{
  "name" : "J5oojcO",
  "cluster_name" : "docker-cluster",
  "cluster_uuid" : "SfkgAJmaT_Sb3erfYUl7sQ",
  "version" : {
    "number" : "5.2.2",
    "build_hash" : "f9d9b74",
    "build_date" : "2017-02-24T17:26:45.835Z",
    "build_snapshot" : false,
    "lucene_version" : "6.4.1"
  },
  "tagline" : "You Know, for Search"
}

提前致谢。

更新

官方指南说镜像是用X-Pack构建的，所以我尝试禁用xpack安全，使用127.0.0.1:9300成功连接到elastic seacrh容器

谢谢。

Answer 1

我不知道为什么文档指示这样做，但是当您传递 127.0.0.1 作为传输主机时，绑定(bind)仅针对该地址，因此无法在外部访问容器。

尝试将 transport.host 也定义为 0.0.0.0，这样它也绑定(bind)到容器 IP。
