elasticsearch:
    image: elasticsearch:7.6.2
    container_name: elasticsearch
    environment:
      - "cluster.name=elasticsearch" #设置集群名称为elasticsearch
      - "discovery.type=single-node" #以单一节点模式启动
      - "ES_JAVA_OPTS=-Xms1024m -Xmx2048m" #设置使用jvm内存大小
    volumes:
      - /mydata/elasticsearch/plugins:/usr/share/elasticsearch/plugins #插件文件挂载
      - /mydata/elasticsearch/data:/usr/share/elasticsearch/data #数据文件挂载
    ports:
      - 9200:9200
      - 9300:9300

解压elasticsearch7.6.2.zip到elasticsearch的plugins：

运行后报错信息：

既然报这个错，就查看这个文件

Caused by: java.nio.file.FileSystemException: /usr/share/elasticsearch/plugins/plugin-descriptor.properties/plugin-descriptor.properties: Not a directory

解决方法：在plugins中新建文件件，名字为analysis-ik，将所有plugins下的elasticsearch文件移动到analysis-ik下面，再次运行docker restart elasticsearch

成功！
