我正在从Docker运行Elasticsearch实例。该图像来自jHipster docker中心仓库：jhipster / jhipster-
elasticsearch /
-我使用的是图像v1.3.2，因为我需要Elasticsearch 2.4.0（以与该项目的Spring Boot版本保持一致）。

我正在使用，Logstash和Kibana图像启动ES容器docker-compose。这是启动ES容器的设置：

jhipster-elasticsearch:
    image: jhipster/jhipster-elasticsearch:v1.3.2
    ports:
        - 9400:9200
        - 9500:9300
    volumes:
       - ./log-es-config/elasticsearch_custom.yml:/usr/share/elasticsearch/config/elasticsearch.yml

因此，我将9400用于REST，并将9500用于传输通信。

这是elasticsearch_custom.yml装入ES config的内部配置：

cluster.name: "log-cluster"
node.name: "log-node"
http.host: 0.0.0.0
transport.host: 127.0.0.1
transport.tcp.port: 9500
transport.publish_port: 9500

当我启动容器时，这就是我从中得到的http://localhost:9400/_nodes：

"cluster_name": "log-cluster",
  "nodes": {
    "xLsGj2DyTdCF89I7sAToVw": {
      "name": "log-node",
      "transport_address": "127.0.0.1:9500",
      "host": "127.0.0.1",
      "ip": "127.0.0.1",
      "version": "2.4.0",
      "build": "ce9f0c7",
      "http_address": "172.18.0.5:9200",
      "settings": {
        "cluster": {
          "name": "log-cluster"
        },
        ... (I can put all response if needed)

JAVA API：

现在，我尝试像这样连接到此ES节点：

    @Bean
    public ElasticsearchOperations logsElasticsearchOperations() throws UnknownHostException {
        Settings settings = Settings.settingsBuilder()
            .put("cluster.name", "log-cluster")
            .put("node.name", "log-node")
            .build();

        Client client = TransportClient.builder()
            .settings(settings)
            .build()
            .addTransportAddress(new InetSocketTransportAddress(new InetSocketAddress("127.0.0.1", 9500)));


        ElasticsearchTemplate template = new ElasticsearchTemplate(client);
        template.createIndex(ProcessLog.class);
        log.debug("Elasticsearch for logs configured.");
        return template;
    }

我遇到的错误是最著名的错误：

Caused by: org.elasticsearch.client.transport.NoNodeAvailableException: None of the configured nodes are available: [{#transport#-1}{127.0.0.1}{127.0.0.1:9500}]

我用谷歌搜索并尝试了不同的配置方法，也将其client.transport.sniff设置为false，但没有一种可行。现在，我花了很多时间尝试配置此服务器，但我仍然缺少一些东西。

在此先感谢您的帮助。

更新：

启动应用程序时，还将运行嵌入式ES实例。所以主机端口配置是这样的：

• 嵌入式ES：9200（http），9300（tcp）
• Docker的ES：9400（http），9500（tcp）

这是完整的docker-compose.yml：
