Kibana 无法连接到 docker 上的 Elasticsearch

Question

我正在关注 https://www.elastic.co/guide/en/elasticsearch/reference/6.5/docker.html 和 https://www.elastic.co/guide/en/kibana/6.5/docker.html 但是用kibana好像不太好用，ES可以用。

我尝试单独启动 kibana，但最后我将它添加到一个 docker-compose 文件中。

services:
  elasticsearch:
    image: docker.elastic.co/elasticsearch/elasticsearch:6.5.4
    container_name: elasticsearch
    environment:
      - cluster.name=docker-cluster
      - bootstrap.memory_lock=true
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
      - esdata1:/usr/share/elasticsearch/data
    ports:
      - 9200:9200
    networks:
      - esnet
  elasticsearch2:
    image: docker.elastic.co/elasticsearch/elasticsearch:6.5.4
    container_name: elasticsearch2
    environment:
      - cluster.name=docker-cluster
      - bootstrap.memory_lock=true
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
      - "discovery.zen.ping.unicast.hosts=elasticsearch"
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
      - esdata2:/usr/share/elasticsearch/data
    networks:
      - esnet

  kibana:
    image: docker.elastic.co/kibana/kibana:6.5.4
    volumes:
      - ./kibana.yml:/usr/share/kibana/config/kibana.yml  
    ports:
    - 5601:5601    

volumes:
  esdata1:
    driver: local
  esdata2:
    driver: local

networks:
  esnet:

Kibana.yml 是：

server.host: "0.0.0.0"
server.name: "kibana"
elasticsearch.url: http://elasticsearch:9200

我收到以下错误：

kibana_1 | {"type":"log","@timestamp":"2019-06-11T08:55:30Z","tags":["warning","elasticsearch","admin"],"pid":1,"message":"Unable to revive connection: http://elasticsearch:9200/"}

Answer 1

kibana 容器与两个 elasticsearch 容器不在同一个网络上：它没有 networks: 块，因此在 automatically-created default 网络，但是两个 elasticsearch 容器在 explicitly-declared esnet 网络上。由于它们不在同一网络上，inter-container DNS 不起作用。

我建议只删除所有 networks: 块并使用 Docker Compose 为您创建的默认网络。如果您想要一个明确命名的网络，请将相同的 networks: [esnet] 行复制到 kibana: 服务块中。
