无法按照CentOS 7上的官方安装指南在虚拟机上安装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，输出是意外的（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

你预期会发生什么:

kubeadm、kubelt和kubelet已安装并启用

如何复制：

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

Docker version: Client:

环境:

Kubernetes版本(使用kubectl版本):无法按照官方指南安装最新版本。硬件配置:虚拟机符合官方指南中的指导原则(2GB ram和2个CPU)操作系统:

NAME="CentOS Linux"
VERSION="7 (Core)"
ID="centos"
ID_LIKE="rhel fedora"
VERSION_ID="7"

内核：

Answer 1

sudo cat <<EOF > /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
EOF
bash: /etc/yum.repos.d/kubernetes.repo: Permission denied

运行此程序后，即使我使用sudo并且我的用户帐户具有管理员权限，我仍然收到拒绝权限的错误。我的问题的解决方案是以root用户身份登录我的RockyLinux并完成安装。

Answer 2

从kubernetes.repo中删除以下行后，它对我有效:

排除=kubelet kubeadm kubectl

Answer 3

您似乎缺少<代码>

另外，我可以看到文档中有一个错误。

应删除包含< code>exclude=kube*的行。

应如下：

cat <<EOF > /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
EOF
setenforce 0
yum install -y kubelet kubeadm kubectl
systemctl enable kubelet && systemctl start kubelet
