rancher2使用containerd了，在node上去跑docker命令找不到以前的那些pod了，查了很久才设置好crictl的配置

kubectl get nodes -o wide
NAME      STATUS   ROLES                              AGE   VERSION           INTERNAL-IP     EXTERNAL-IP   OS-IMAGE             KERNEL-VERSION      CONTAINER-RUNTIME
master1   Ready    control-plane,etcd,master,worker   28d   v1.26.15+rke2r1   192.168.18.28   <none>        Ubuntu 20.04.6 LTS   5.4.0-186-generic   containerd://1.7.11-k3s2
node1     Ready    control-plane,etcd,master,worker   28d   v1.26.15+rke2r1   192.168.18.27   <none>        Ubuntu 20.04.6 LTS   5.4.0-186-generic   containerd://1.7.11-k3s2
node2     Ready    control-plane,etcd,master,worker   28d   v1.26.15+rke2r1   192.168.18.29   <none>        Ubuntu 20.04.6 LTS   5.4.0-186-generic   containerd://1.7.11-k3s2

然后

设置/etc/crictl.yaml
runtime-endpoint: /var/run/k3s/containerd/containerd.sock
image-endpoint: /var/run/k3s/containerd/containerd.sock
timeout: 10
#debug: true

然后安装crictl：VERSION="v1.30.0" # check latest version in /releases page
wget https://github.com/kubernetes-sigs/cri-tools/releases/download/$VERSION/crictl-$VERSION-linux-amd64.tar.gz
sudo tar zxvf crictl-$VERSION-linux-amd64.tar.gz -C /usr/local/bin
rm -f crictl-$VERSION-linux-amd64.tar.gz
