当我运行时，kubeadm upgrade plan我得到：
[preflight] Running pre-flight checks. [upgrade] Making sure the cluster is healthy: [upgrade/config] Making sure the configuration is correct: [upgrade/config] Reading configuration from the cluster... [upgrade/config] FYI: You can look at this config file with 'kubectl -n kube-system get cm kubeadm-config -oyaml' [upgrade/config] FATAL: unexpected error when reading kubeadm-config ConfigMap: ClusterConfiguration key value pair missing
这个配置图是什么以及如何获取它？

此消息来自kubeadm1.13 二进制文件。执行kubeadm upgrade1.10 -> 1.11 时，请确保使用kubeadm1.11 二进制文件。同样，kubeadm从 1.11 -> 1.12 时，请使用 1.12 二进制文件。
