ctr containers ls 什么都没有

当我使用 "ctr containers ls "命令来获取正在运行的容器时,我什么也得不到。

# ctr containers ls
CONTAINER    IMAGE    RUNTIME

但是,当我使用命令systemctl status containers来获取有关 containerd 的信息时。我发现有很多容器。比如:

# systemctl status containerd

containerd默认命名空间的,如果是基于k8s的,默认命名空间是k8s.io,加上就可以了:

ctr --namespace k8s.io containers ls
