Kubeadm踩坑

系统：cent os

第一个错误如图：

【ERROR KubeletVersion】：the kubelet version is higher than the control plane version. This is not a supportted version skew and may lead to a malfunctional cluster.

看来主要是版本不匹配的问题，所以我重新装了一下kubernete

yum -y remove kubelet
yum -y install kubelet-1.12.1 kubeadm-1.12.1

问题就解决了。
