elasticsearch docker部署的问题

Question

学习使用docker部署elasticsearch,
yaml 文件如下

version: '2.2'
services:
 cerebro:
   image: lmenezes/cerebro:0.9.0
   container_name: cerebro
   ports:
     - "9001:9001"
   command:
     - -Dhosts.0.host=http://elasticsearch:9200
   networks:
     - es7net
 kibana:
  
   image: docker.elastic.co/kibana/kibana:7.6.2
   container_name: kibana7
   environment:
     - I18N_LOCALE=zh-CN
     - XPACK_GRAPH_ENABLED=true
     - TIMELION_ENABLED=true
     - XPACK_MONITORING_COLLECTION_ENABLED="true"
   ports:
     - "5601:5601"
   networks:
     - es7net
 elasticsearch:
   image: docker.elastic.co/elasticsearch/elasticsearch:7.6.2
   container_name: es7_01
   environment:
     - cluster.name=geektime
     - node.name=es7_01
     - bootstrap.memory_lock=true
     - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
     - discovery.seed_hosts=es7_01,es7_02
     - cluster.initial_master_nodes=es7_01,es7_02
   ulimits:
     memlock:
       soft: -1
       hard: -1
   volumes:
     - es7data1:/usr/share/elasticsearch/data
   ports:
     - 9200:9200
   networks:
     - es7net
 elasticsearch2:
   image: docker.elastic.co/elasticsearch/elasticsearch:7.6.2
   container_name: es7_02
   environment:
     - cluster.name=geektime
     - node.name=es7_02
     - bootstrap.memory_lock=true
     - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
     - discovery.seed_hosts=es7_01,es7_02
     - cluster.initial_master_nodes=es7_01,es7_02
   ulimits:
     memlock:
       soft: -1
       hard: -1
   volumes:
     - es7data2:/usr/share/elasticsearch/data
   networks:
     - es7net

volumes:
 es7data1:
   driver: local
 es7data2:
   driver: local

networks:
 es7net:
   driver: bridge

运行 docker-compose 报错

不知道哪里出问题了,请高手指正一下
还有这段配置什么意思了,不是很理解
command:

 - -Dhosts.0.host=http://elasticsearch:9200

Answer 1

参考https://www.elastic.co/guide/...

docker pull docker.elastic.co/kibana/kibana:7.13.2
docker run --name kib01-test --net elastic -p 5601:5601 -e "ELASTICSEARCH_HOSTS=http://es01-test:9200" docker.elastic.co/kibana/kibana:7.13.2

而你的docker-compose

kibana:
  
   image: docker.elastic.co/kibana/kibana:7.6.2
   container_name: kibana7
   environment:
     - I18N_LOCALE=zh-CN
     - XPACK_GRAPH_ENABLED=true
     - TIMELION_ENABLED=true
     - XPACK_MONITORING_COLLECTION_ENABLED="true"
   ports:
     - "5601:5601"
   networks:
     - es7net

所以问题应该是你的 kibana 没设置 ELASTICSEARCH_HOSTS 环境变量导致的 kibana 服务未能找到 es 服务。
