docker 命令无响应的排查思路

1. df -h 查看磁盘空间是否充足
2. docker容器有问题，需要清空docker容器【操作有风险，注意备份】
   docker容器位置

cd /var/lib/docker/containers

Docker containers are stored in the default location at /var/lib/docker/ on Linux. If you can identify the container and delete this, and then try to start docker. If you are successful and you can run the docker ps -a command successfully, then you can start deleting traces of this container.
Note: I would snapshot your VM before attempting to try this.

docker无响应，起不来，把对应的容器删掉，然后重启虚拟机就可以了
