错误原因

wsl2本身的bug，具体原因不详

解决办法

• quit docker desktop
• stop docker service in service.msc which should be called com.docker.service
  
• shutdown wsl: wsl --shutdown
• start docker windows

wsl2的使用

windows 的docker desktop只是基于wsl中的linux做初始化，真正的docker守护进程并不在linux内。所以在对应的wsl系统中，敲击docker命令会得到如下问题

Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

所以，一切的docker的管理，还得在windows的shell中进行
