本实验安装 Kubernetes 1.23.6 版本。

yum.repos.d/kubernetes.repo:

[kubernetes]
name=Kubernetes
baseurl=http://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-$basearch
enabled=1
gpgcheck=0
repo_gpgcheck=0
gpgkey=http://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg http://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg
exclude=kubelet kubeadm kubectl

[root@maxiaoke deploy-kubernetes]# gosh push -i node.ip yum.repos.d/kubernetes.repo /etc/yum.repos.d/
# 安装1.23.6版本，可以根据需求安装指定版本
[root@maxiaoke deploy-kubernetes]# gosh cmd -i node.ip "yum search kubelet kubeadm kubectl --disableexcludes=kubernetes --showduplicates|grep 1.23.6"
10.4.7.81
kubelet-1.23.6-0.x86_64 : Container cluster management
kubeadm-1.23.6-0.x86_64 : Command-line utility for administering a Kubernetes
kubectl-1.23.6-0.x86_64 : Command-line utility for interacting with a Kubernetes
[root@maxiaoke deploy-kubernetes]# gosh cmd -i node.ip "yum install -y --disableexcludes=kubernetes kubelet-1.23.6-0.x86_64 kubeadm-1.23.6-0.x86_64 kubectl-1.23.6-0.x86_64"
[root@maxiaoke deploy-kubernetes]# gosh cmd -i node.ip "systemctl start kubelet ; systemctl enable kubelet"
# 安装kubelet 时候会安装CNI插件的，如果你在安装containerd时候按照官方文档安装了新版本CNI二进制，可能存在冲突
[root@maxiaoke deploy-kubernetes]# gosh cmd -i node.ip "ls /opt/cni"
