Debian上如何快速安装K8s

以下是在Debian上快速安装K8s的步骤：

1. 更新系统：sudo apt update && sudo apt upgrade -y
2. 安装Docker：
   • sudo apt install apt-transport-https ca-certificates curl
   • curl -fsSL https://download.docker.com/linux/debian/gpg | sudo apt-key add -
   • echo "deb [arch=amd64] https://download.docker.com/linux/debian $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list
   • sudo apt update && sudo apt install -y docker-ce docker-ce-cli containerd.io
   • sudo systemctl start docker && sudo systemctl enable docker
3. 禁用Swap：
   • sudo swapoff -a
   • sudo sed -i '/ swap / s/^\(.*\)$/#\1/g' /etc/fstab
4. 安装Kubernetes工具：
   • curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add -
   • echo "deb https://apt.kubernetes.io/ kubernetes-xenial main" | sudo tee /etc/apt/sources.list.d/kubernetes.list
   • sudo apt update && sudo apt install -y kubelet kubeadm kubectl
   • sudo apt-mark hold kubelet kubeadm kubectl
5. 初始化主节点：sudo kubeadm init --pod-network-cidr=10.244.0.0/16（可根据需要修改参数）
6. 配置kubectl：
   • mkdir -p $HOME/.kube
   • sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
   • sudo chown $(id -u):$(id -g) $HOME/.kube/config
7. 安装网络插件（可选）：如安装Flannel，kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml
8. 加入工作节点：在每个工作节点上执行sudo kubeadm join <master-ip>:6443 --token <token> --discovery-token-ca-cert-hash sha256:<hash>
