解決無法删除狀态為Dead的容器

docker 強制删除（rm -f）container時出現錯誤提示

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

檢視容器狀态

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

發現它是 status為dead的容器，實際上，吞掉這個錯誤就可以了

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

再次檢視發現已經删除掉了

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