kubernetes升级到v1.8.0后报错：unknown flag: --experimental-upload-certs

现象：

[root@master cluster]# kubeadm init --config=kubeadm.yml --experimental-upload-certs|tee kubeadm=init.log
unknown flag: --experimental-upload-certs
To see the stack trace of this error execute with --v=5 or higher

 

 之前版本为v1.4.0时该命令正常执行

解决办法:  将–experimental-upload-certs 替换为 --upload-certs

kubeadm init --config=kubeadm.yml --upload-certs | tee kubeadm-init.log
