Kubernetes节点的安装失败与CentOs 7上的冲突软件包
当我试图用下面的命令安装kubernetes-node时，它会失败并显示错误

你正在混合docker包。 软件包docker是Redhat的Docker。 包装docker-engine是Docker的Docker。 kubernetes-node有Docker的docker dependency +，你也要安装Redhat的Docker =>冲突。 尝试：
sudo yum install docker-engine kubernetes-node
它可能是因为你已经安装了docker，我假设docker回购的最新版本。 该命令试图从不同的回购安装。 尝试运行而不是：
sudo yum install -y kubelet kubeadm kubectl kubernetes-cni
它将在没有docker的情况下安装所需的kubernetes工具。
