1.16中出现的问题已经不存在了。

问题总结

部署时有时会碰到如下错误提示，原因未定，重新执行就不再出现此问题。

"error: the server doesn't have a resource type \"clusterrolebinding\"\nerror: no matches for kind \"ClusterRoleBinding\" in version \"rbac.authorization.k8s.io/v1beta1\"", "stderr_lines": ["error: the server doesn't have a resource type \"clusterrolebinding\"", "error: no matches for kind \"ClusterRoleBinding\" in version \"rbac.authorization.k8s.io/v1beta1\""],
