传送门

2，安装步骤

a) 拉取镜像

docker pull docker.elastic.co/elasticsearch/elasticsearch:7.5.2

b) 启动容器

• 单节点

 docker run -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" docker.elastic.co/elasticsearch/elasticsearch:7.5.2

启动后查询

注意：

       1）此种方式启动后，需要放开9200和9300两个端口。

       2）在容器中，elasticsearch.yml中，添加跨域配置。

• 使用docker编排方式，启动多节点

1st 创建编排文件docker-compose.yml

文件内容如下

version: '2.2'
services:
  es01:
    image: docker.elastic.co/elasticsearch/elasticsearch:7.5.2
    container_name: es01
    environment:

      - bootstrap.memory_lock=true
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
      - data01:/usr/share/elasticsearch/data
    ports:
      - 9200:9200
    networks:
      - elastic
  es02:

    environment:
      - node.name=es03

    volumes:
      - data03:/usr/share/elasticsearch/data
    networks:
      - elastic

volumes:
  data01:
    driver: local
  data02:
    driver: local
  data03:
    driver: local

networks:
  elastic:
    driver: bridge

2nd 启动编排

docker-compose up

3rd 查询相关节点信息

4th 停止

docker-compose down
