我正在使用docker compose启动一些容器，这些容器形成了solr和zookeeper节点的集群。
这是我的撰写文件（取自此处）：

如果我跑 docker compose ls ，我看到项目正在正确运行：

NAME                STATUS
solr-cluster        running(6)

这是 docker container ls :

如果我尝试使用浏览器使用主机导航solr节点 localhost （例如。 http://localhost:8983/ )，容器使用solr admin接口正确响应。
但是，如果我尝试使用浏览器访问同一容器，但从其ip访问（例如。 http://172.23.0.7:8983/ 哪里 172.23.0.7 知识产权是什么 solr3 容器）我得到一个连接超时。如果我尝试ping该ip，我也会收到连接超时。
为什么会发生这种情况？两个都不应该吗 localhost 及 172.23.0.7 主持人工作？
我需要从容器的ip访问容器，因为solr节点使用其ip向zookeeper注册。因此，由于我无法从容器的ip访问容器，因此当我尝试通过solrj API以编程方式连接到容器时，会出现connectiontimeout异常：

public static void main(String[] args)
{
    List<String> zkNodes = new ArrayList<>(3);

    zkNodes.add("localhost:2181");
    zkNodes.add("localhost:2182");
    zkNodes.add("localhost:2183");

    SolrClient solrClient = new CloudSolrClient.Builder(zkNodes, Optional.empty())
        .withConnectionTimeout(10000)
        .withSocketTimeout(10000)
        .build();

    try
    {
        CollectionAdminRequest.listCollections(solrClient);
    }
    catch (IOException | SolrServerException e)
    {
        e.printStackTrace();
    }
}

这是我得到的例外：

我不知道这是否有帮助，但无论如何我在windows主机上，所以我不能使用 --network host Docker 的旗帜。

这个 172.x.x.x IP是仅可在docker网络（即solr和zookeeper节点之间）内访问的IP。
当您从外部连接到zookeeper时，zookeeper不知道有“外部”，它只知道其网络中solr服务器的ip并将其发送回您。但这些IP无法从“外部”访问。
一种解决方法是直接连接到solr服务器，而不是使用zookeeper（URL如 localhost:8981 及 HttpSolrClient ).
或者，您需要告诉solr服务器将外部ip“呈现”给zookeeper。

我认为solar示例的广告地址是docker示例的ip，端口是默认的，而不是重定向的。您应该在POD中注册docker端口，而不是solr端口。
也许solr.xml中的solrcloud部分会有所帮助，但不确定。。。
