【解决】Error: …… Requires: kubernetes-cni >= 0.7.5

【我的问题】使用yum安装旧版本kubeadm和kubelet时，提示缺少依赖 kubernetes-cni

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

 

【解决办法】加上参数 --setopt=obsoletes=0 即可，大概意思支持旧版本。

我使用的是阿里云镜像源，之前一直都是没有问题的，直到最近发现不加参数就会一直报错。
