 添加阿里云的 Kubernetes 源：

sudo tee /etc/apt/sources.list.d/kubernetes.list <<EOF
   deb http://mirrors.aliyun.com/kubernetes/apt kubernetes-xenial main
   EOF

2. 导入阿里云的 GPG 密钥：

curl https://mirrors.aliyun.com/kubernetes/apt/doc/apt-key.gpg | sudo apt-key add -

systemctl stop ufw && systemctl disable ufw
sudo swapoff -a
sudo modprobe br_netfilter
echo '1' | sudo tee /proc/sys/net/bridge/bridge-nf-call-iptables
sudo nano /etc/sysctl.conf
在文件的末尾添加以下两行配置
net.bridge.bridge-nf-call-iptables = 1 
net.ipv4.ip_forward = 1

sudo sysctl -p

sudo apt-get update
sudo apt-get install -y kubelet kubeadm kubectl

 

sudo lsof -i :80

以下指令适用于 Kubernetes 1.28.

1. 更新 apt 包索引并安装使用 Kubernetes apt 仓库所需要的包：

   sudo apt-get update
   # apt-transport-https 可能是一个虚拟包（dummy package）；如果是的话，你可以跳过安装这个包
   sudo apt-get install -y apt-transport-https ca-certificates curl gpg
   

2. 下载用于 Kubernetes 软件包仓库的公共签名密钥。所有仓库都使用相同的签名密钥，因此你可以忽略URL中的版本：

   curl -fsSL https://pkgs.k8s.io/core:/stable:/v1.28/deb/Release.key | sudo gpg --dearmor -o /etc/apt/keyrings/kubernetes-apt-keyring.gpg
   

3. 添加 Kubernetes apt 仓库。 请注意，此仓库仅包含适用于 Kubernetes 1.28 的软件包； 对于其他 Kubernetes 次要版本，则需要更改 URL 中的 Kubernetes 次要版本以匹配你所需的次要版本 （你还应该检查正在阅读的安装文档是否为你计划安装的 Kubernetes 版本的文档）。

   # 此操作会覆盖 /etc/apt/sources.list.d/kubernetes.list 中现存的所有配置。
   echo 'deb [signed-by=/etc/apt/keyrings/kubernetes-apt-keyring.gpg] https://pkgs.k8s.io/core:/stable:/v1.28/deb/ /' | sudo tee /etc/apt/sources.list.d/kubernetes.list
   

4. 更新 apt 包索引，安装 kubelet、kubeadm 和 kubectl，并锁定其版本：

   sudo apt-get update
   sudo apt-get install -y kubelet kubeadm kubectl
   sudo apt-mark hold kubelet kubeadm kubectl
