简介： 加速你的容器管理！轻松安装kubeadm、kebelet和kubectl！

1 kubernetes镜像切换成国内源

访问阿里云镜像：

M1M2芯片的arm64架构需要更改：

cat > /etc/yum.repos.d/kubernetes.repo << EOF
[kubernetes]
name=Kubernetes
baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64
enabled=1
gpgcheck=0
repo_gpgcheck=0
gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg
EOF

2 安装 kubelet/kubeadm/kubectl

注意指定版本！否则直接给你安装了最新版。

yum install -y kubelet-1.27.0 kubeadm-1.27.0 kubectl-1.27.0

3 启动 kebelet

3.1 自启动

kebelet是任务执行者，需要配置成开机自启动

[root@icv-k8s-node-1 ~]# systemctl enable kubelet
Created symlink from /etc/systemd/system/multi-user.target.wants/kubelet.service to /usr/lib/systemd/system/kubelet.service.
[root@icv-k8s-node-1 ~]# systemctl start kubelet
[root@icv-k8s-node-1 ~]# 
systemctl status kubelet

3.2 启动kubelet失败

查看kebelet状态：

[root@icv-k8s-node-1 ~]# systemctl status kubelet
● kubelet.service - kubelet: The Kubernetes Node Agent
   Loaded: loaded (/usr/lib/systemd/system/kubelet.service; enabled; vendor preset: disabled)

[root@icv-k8s-node-1 ~]#

因为 k8s 还没配置完全呢。

禁用containerd

vim /etc/containerd/config.toml

重启：

[root@icv-k8s-node-2 ~]# systemctl restart containerd
[root@icv-k8s-node-2 ~]# systemctl restart kubelet
[root@icv-k8s-node-2 ~]# systemctl status kubelet
