Question

我使用OFFICIAL REPO elasticsearch docker镜像设置了elasticsearch容器。然后用

运行它

docker run -dP elasticsearch

简单而有效。 ps信息是

CONTAINER ID        IMAGE                  COMMAND                CREATED             STATUS              PORTS                                              NAMES
658b49ed9551        elasticsearch:latest   "/docker-entrypoint.   2 seconds ago       Up 1 seconds        0.0.0.0:32769->9200/tcp, 0.0.0.0:32768->9300/tcp   suspicious_albattani

我可以通过端口32769-> 9200

使用http-client访问服务器

baihetekiMacBook-Pro:0 baihe$ curl 10.211.55.100:32769
{
  "status" : 200,
  "name" : "Scorpia",
  "cluster_name" : "elasticsearch",
  "version" : {
    "number" : "1.4.5",
    "build_hash" : "2aaf797f2a571dcb779a3b61180afe8390ab61f9",
    "build_timestamp" : "2015-04-27T08:06:06Z",
    "build_snapshot" : false,
    "lucene_version" : "4.10.4"
  },
  "tagline" : "You Know, for Search"
}

现在我需要我的JAVA程序来使用dockerized elasticsearch。 Java节点客户端只能通过32768-> 9300（群集节点通话端口）连接到elasticsearch。所以我像我这样在我的java中配置传输客户端

    Settings settings = ImmutableSettings.settingsBuilder()
            .put("client.transport.sniff", true)
            .put("client.transport.ignore_cluster_name", true).build();
    client = new TransportClient(settings);
    ((TransportClient) client)
    .addTransportAddress(new InetSocketTransportAddress(
            "10.211.55.100", 32768));

然后我在控制台中收到以下错误：

当我直接在主机中运行elasticsearch时。一切都很好。

我在docker hub上检查elasticsearch的所有dockerfile。似乎所有人都只是做了以下事情：

EXPOSE 9200 9300

我想知道有没有人试图做类似的事情。 9300是普通的TCP端口还是UDP端口？在运行容器时是否需要做一些特殊的事情？谢谢！

Answer 1

如果您将"client.transport.sniff"设置为false，则应该有效。

如果您仍想使用嗅探，请按照下面的说明操作： https://github.com/olivere/elastic/wiki/Docker

这对我有用（在docker-compose.yml中）。

version: "2"
services:
    elasticsearch5:
        image: docker.elastic.co/elasticsearch/elasticsearch:5.5.3
        container_name: elasticsearch5
        environment:
            - cluster.name=elasticsearch5-cluster
            - http.host=0.0.0.0
            - network.publish_host=127.0.0.1
            - transport.tcp.port=9700
            - discovery.type=single-node
            - xpack.security.enabled=false
        ports:
            - "9600:9200"
            - "9700:9700"

指定network.publish_host和transport.tcp.port似乎可以解决问题。并且sniff = true仍然有效。

无法通过java-client连接到Dockerized elasticsearch
