推荐答案
Reproduced your issue by installing v.1.10.4 version and trying to upgrade it to v.1.11.0 using https://kubernetes.io/docs/tasks/administer-cluster/kubeadm/kubeadm-upgrade-1-11/ FAQ.
相同的错误，并尝试升级到1.12.1而不是1.11.0
The same error and attempt to upgrade to 1.12.1 instead of 1.11.0
[升级/配置]致命:无效的配置:种类和apiVersion为 必须在所有YAML文档中指定的强制性信息
[upgrade/config] FATAL: invalid configuration: kind and apiVersion is mandatory information that needs to be specified in all YAML documents
之所以发生这种情况，是因为您在使用以下命令时将v1.12.1传递给$ VERSION:
This is happening because you pass v1.12.1 to $VERSION while using below command:
export VERSION=$(curl -sSL https://dl.k8s.io/release/stable.txt)
root@kube-update-11:~# echo $VERSION
v1.12.1
v1.12.1
您应该手动设置正确的版本:
What you should do is manually set proper version:
export VERSION=v1.11.0
export ARCH=amd64
curl -sSL https://dl.k8s.io/release/${VERSION}/bin/linux/${ARCH}/kubeadm > /usr/bin/kubeadm
chmod a+rx /usr/bin/kubeadm
然后重试
root@kube-update-11:~# kubeadm upgrade plan
