解决无法删除状态为Dead的容器

docker 强制删除（rm -f）container时出现错误提示

[root@Ieat1 ~]# docker rm -f nginx
Error response from daemon: Driver devicemapper failed to remove root filesystem a838d837988a593de3e997748cc80b1540dd31697f66e93dad275fbeaa5b3278: Device is Busy

查看容器状态

[root@Ieat1 ~]# docker ps -a|grep nginx
a838d837988a        nginx                                                   "nginx -g 'daemon ..."   3 weeks ago         Dead 

发现它是 status为dead的容器，实际上，吞掉这个错误就可以了

docker stop nginx 1>/dev/null 2>&1 | exit 0
docker rm -f nginx 1>/dev/null 2>&1 | exit 0

再次查看发现已经删除掉了

[root@Ieat1 ~]# docker ps -a|grep nginx
