services:

  elasticsearch:
    image: elasticsearch:7.9.3
    container_name: elasticsearch7.9.3
    environment:
      - bootstrap.memory_lock=true   # 内存交换的选项，官网建议为true
      - "ES_JAVA_OPTS=-Xms256m -Xmx256m" # 设置内存，如内存不足，可以尝试调低点
      - discovery.type=single-node      # 是否启用单节点模式
    ulimits:        # 栈内存的上限
      memlock:
        soft: -1    # 不限制
        hard: -1    # 不限制
    # volumes:
    #  - ~/top/data/elasticsearch/config:/usr/share/elasticsearch/config
    #  - ~/top/data/elasticsearch/data:/usr/share/elasticsearch/data
    #  - ~/top/data/elasticsearch/logs:/usr/share/elasticsearch/logs
    hostname: elasticsearch
    restart: always
    ports:
      - 9200:9200
      - 9300:9300


  kibana:
    image: kibana:7.9.3
    container_name: kibana7.9.3
    environment:
      - elasticsearch.hosts=http://elasticsearch:9200
    hostname: kibana
    depends_on:
      - elasticsearch
    restart: always
    ports:
      - 5601:5601

volumes:
  esdata:
    driver: local

运行

docker-compose up -d

将容器内的config配置文件复制到需要挂载的目录

docker cp elasticsearch7.9.3:/usr/share/elasticsearch/config ~/top/data/elasticsearch/

删除刚刚创建好的容器

docker rm elasticsearch7.9.3 kibana7.9.3

打开docker-compose.yml中挂载目录的注释

volumes:
  - ~/top/data/elasticsearch/config:/usr/share/elasticsearch/config
  - ~/top/data/elasticsearch/data:/usr/share/elasticsearch/data
  - ~/top/data/elasticsearch/logs:/usr/share/elasticsearch/logs

运行

docker-compose up -d

运行成功

Elasticsearch: 访问9200端口
Kibana: 访问5601端口

安装ik分词插件

docker-compose exec elasticsearch elasticsearch-plugin install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v7.9.3/elasticsearch-analysis-ik-7.9.3.zip

//然后要重启es容器
docker-compose restart elasticsearch
