8-docker 无法删除dead状态的容器

docker rm 的时候，死活删除不了容器，docker kill也不行 ，容器状态是dead，重启docker服务也试过了，不行
想到可能是我迁移过docker容器的存储地址导致的，不太确定原因

以下为自己实践过程，建议先看完教程再实践，后面有坑：

按照上面一顿操作后，发现nginx转发异常，项目无法访问
赶紧用这个方法：https://www.jianshu.com/p/19cefdedc3fc
cd /var/run
touch nginx.pid
输入nginx的进程id（master process对应的那个id）
nginx -s reload
发现还是不行，继续执行
nginx -c /etc/nginx/nginx.conf
nginx -s reload
ok，完成！
