无法在 VM 上按照 CentOS 7 官方安装指南安装 Kubernetes 最新版本

Question

当我执行以下命令（取自 kubernetes 的官方安装指南）时，输出出乎意料（如下所示：） 命令（在 CentOS 7 上）：

cat < /etc/yum.repos.d/kubernetes.repo
[kubernetes]
name=Kubernetes
baseurl=https://packages.cloud.google.com/yum/repos/kubernetes-el7-x86_64
enabled=1
gpgcheck=1
repo_gpgcheck=1
gpgkey=https://packages.cloud.google.com/yum/doc/yum-key.gpg 
https://packages.cloud.google.com/yum/doc/rpm-package-key.gpg
exclude=kube*
EOF
setenforce 0
yum install -y kubelet kubeadm kubectl
systemctl enable kubelet && systemctl start kubelet

输出：

Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile

base: centos.sonn.com
extras: mirror.sesp.northwestern.edu
updates: mirrors.cat.pdx.edu
kubernetes/signature | 454 B 00:00:00
kubernetes/signature | 1.4 kB 00:00:00 !!!
kubernetes/primary | 33 kB 00:00:00
kubernetes 237/237
No package kubelet available.
No package kubeadm available.
No package kubectl available.
Error: Nothing to do

你期望发生的事情：

kubeadm、kubeclt 和 kubelet 已安装并启用

如何重现它：

在 centos 7 上运行上述命令（按照https://kubernetes.io/docs/setup/independent/install-kubeadm/ 上的指南）

你似乎<<EOF在第一行的末尾失踪了。

另外，我可以看到有一个错误的文档。

exclude=kube*应删除包含的行。

应该如下所示：

cat <<EOF > /etc/yum.repos.d/kubernetes.repo
