我正在尝试用一个节点（VM 机器）启动一个集群，但我得到了一些 podkube-system卡住了ContainerCreating

当我将描述失败的豆荚时，我得到了：

曾尝试再次重新注册该节点，但没有运气。有什么想法吗？

正如它所说的未经授权，因此您必须授予 rbac 权限才能使其正常工作。

尝试添加

apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: system:calico-node
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: calico-node
subjects:
- apiGroup: rbac.authorization.k8s.io
  kind: Group
  name: system:nodes

修复了https://rancher.com/docs/rancher/v2.x/en/cluster-admin/cleaning-cluster-nodes/中关于如何回收损坏节点的文章的问题。
