Kibana无法恢复与ElasticSearch的连接

Question

我是ElasticSearch的新手，我遵循这里的说明：https://www.elastic.co/guide/en/elasticsearch/reference/current/docker.html

每当我运行“docker compose up”时，Kibana总是说“无法恢复连接”，但如果我运行curlhttp://localhost:9200，我会得到回复：

{
  "name" : "ec88fa675367",
  "cluster_name" : "docker-cluster",
  "cluster_uuid" : "UkLkAHO8S4yzAKFaf0KsYA",
  "version" : {
    "number" : "7.5.0",
    "build_flavor" : "default",
    "build_type" : "docker",
    "build_hash" : "e9ccaed468e2fac2275a3761849cbee64b39519f",
    "build_date" : "2019-11-26T01:06:52.518245Z",
    "build_snapshot" : false,
    "lucene_version" : "8.3.0",
    "minimum_wire_compatibility_version" : "6.8.0",
    "minimum_index_compatibility_version" : "6.0.0-beta1"
  },
  "tagline" : "You Know, for Search"
}

下面是我的docker compose。yml，请帮忙，谢谢！

version: '3'

networks:
  elastic:

services:
  elasticsearch:
    image: docker.elastic.co/elasticsearch/elasticsearch:7.5.0
    container_name: elasticsearch
    networks:
      - elastic
    environment:
      - discovery.type=single-node
    ports:
      - 9200:9200

  kibana:
    image: docker.elastic.co/kibana/kibana:7.5.0
    container_name: kibana
    networks:
      - elastic
    environment:
      SERVER_NAME: kibana
      ELASTICSEARCH_HOSTS: http://localhost:9200
    links:
      - elasticsearch
    depends_on:
      - elasticsearch

Answer 1

它不起作用的原因是，您正在将ELASICSEARCH_HOSTS设置为Kibana主机（因为localhost代表Kibana容器）。您需要做的是使用elasticsearch主机名elasticsearch\u主机：http://elasticsearch:9200。

您还需要映射Kibana端口，否则您将无法从本地机器访问它（类似于您为elasticsearch所做的）。

下面的例子应该有用：

version: '3'

networks:
  elastic:

services:
  elasticsearch:
    image: docker.elastic.co/elasticsearch/elasticsearch:7.5.0
    container_name: elasticsearch
    networks:
      - elastic
    environment:
      - discovery.type=single-node
    ports:
      - 9200:9200

  kibana:
    image: docker.elastic.co/kibana/kibana:7.5.0
    container_name: kibana
    networks:
      - elastic
    environment:
      SERVER_NAME: kibana
      ELASTICSEARCH_HOSTS: http://elasticsearch:9200
    links:
      - elasticsearch
    depends_on:
      - elasticsearch
    ports:
      - 5601:5601
