[root@192_168_31_102 ~]# docker container prune
WARNING! This will remove all stopped containers.
Are you sure you want to continue? [y/N] N

我们利用管道，直接非交互式执行
[root@192_168_31_102 ~]# echo y | docker container prune
WARNING! This will remove all stopped containers.
Are you sure you want to continue? [y/N] Deleted Containers:
