当yum安装kebelet错误时安装k8s

Question

在安装K8S 1.16.4的过程中遇到了这个问题。4提示说它缺少Kubenpilies-CNI 0.7.5的依赖性

但是如果您直接使用YUM安装Kubenpiles cni 0.7.5，kubelet 1.18将自动安装完整信息

[root@k8s-node-2 yum.repos.d]# yum install -y kubelet-1.16.4-0
Loaded plugins: fastestmirror

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

这也是我们今天遇到的问题。

我发现yum repo是在6/21更新的，所以我猜这是yum repo的bug。

通过删除yum的缓存目录，并从已经安装了k8s的旧服务器上复制它，修复了它。

rm -rf /var/cache/yum/x86_64/7/kubernetes
scp x.x.x.x:/var/cache/yum/x86_64/7/kubernetes /var/cache/yum/x86_64/7/
