k3s 中如何使用 nerdctl

也许应该反过来说，怎么使用 nerdctl 操作 k3s 自带的 containerd

系统上安装了 k3s 但是想使用 nerdctl 去操作 containerd 的时候，只是指定 k3s containerd 的 socket 发现并不能看到导入的镜像或者运行中的容器

nerdctl -H /run/k3s/containerd/containerd.sock images
REPOSITORY    TAG    IMAGE ID    CREATED    PLATFORM    SIZE    BLOB SIZE

nerdctl -H /run/k3s/containerd/containerd.sock ps
CONTAINER ID    IMAGE    COMMAND    CREATED    STATUS    PORTS    NAMES

搜了下发现了官方 issue 中已经有人回答了，需要额外指定 --namespace=k8s.io

nerdctl -H /run/k3s/containerd/containerd.sock --namespace=k8s.io images
REPOSITORY                            TAG                                                                 IMAGE ID        CREATED         PLATFORM       SIZE         BLOB SIZE
mysql                                 5.7.37-debian                                                       85334e890204    3 months ago    linux/amd64    441.5 MiB    433.9 MiB

关于 containerd namespace 的说明可以参考文档：https://github.com/containerd/containerd/blob/main/docs/namespaces.md

相关源码应该就是这两个位置：
