rke2集群命令行调试方法
CLI 工具
RKE2 附带了多个 CLI 工具来帮助你访问和调试集群。启动时，它们会被提取到 /var/lib/rancher/rke2/bin。
kubectl
admin kubeconfig 在 /etc/rancher/rke2/rke2.yaml 处生成。
示例：
export KUBECONFIG=/etc/rancher/rke2/rke2.yaml
/var/lib/rancher/rke2/bin/kubectl get nodesContainerd
RKE2 附带了 ctr 和 crictl。Containerd 套接字位于 /run/k3s/containerd/containerd.sock。
示例：
/var/lib/rancher/rke2/bin/ctr --address /run/k3s/containerd/containerd.sock --namespace k8s.io container ls
export CRI_CONFIG_FILE=/var/lib/rancher/rke2/agent/etc/crictl.yaml
/var/lib/rancher/rke2/bin/crictl psEtcd
