Docker部署集群版Elasticsearch

参考： https://blog.youkuaiyun.com/UbuntuTouch/article/details/100919273

安装docker

省略

拉取镜像

docker pull elasticsearch:7.14.1
docker pull kibana:7.14.1

docker-compose启动Elasticsearch和kibana

docker-compose.yml

version: '2.2'
services: 
  es01:
    image: elasticsearch:7.14.1
    container_name: es01
    environment:
      - node.name=es01
      - discovery.seed_hosts=es02
      - cluster.initial_master_nodes=es01,es02
      - cluster.name=docker-cluster
      - bootstrap.memory_lock=true 			#开启内存锁定检查
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m" 	#限制堆大小
    ulimits: 	#内存锁定
      memlock:
        soft: -1
        hard: -1
  es02:
    image: elasticsearch:7.14.1
    container_name: es02
    environment:
      - node.name=es02
      - discovery.seed_hosts=es01
      - cluster.initial_master_nodes=es01,es02
      - cluster.name=docker-cluster
      - bootstrap.memory_lock=true
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
    ulimits:
      memlock:
        soft: -1
        hard: -1
  kibana:
    image: kibana:7.14.1
    container_name: kibana
    environment:
      - SERVER_NAME=kibana.localhost
      - ELASTICSEARCH_HOSTS=http://es01:9200
      - I18N_LOCALE=zh-CN
    ports:
      - 5601:5601
    depends_on:
      - es01

访问 http://XXX.XXX:5601 进入Kibana页面，在开发工具中查看节点信息，可以看到集群中存在两个节点 es01 和 es02
