一、安装kubelet、kubeadm和kubectl

下载并添加k8s安装密钥

sudo apt update && sudo apt install -y apt-transport-https curl
curl -s https://mirrors.aliyun.com/kubernetes/apt/doc/apt-key.gpg | sudo apt-key add -

配置k8s的源

sudo touch /etc/apt/sources.list.d/kubernetes.list 
sudo echo "deb http://apt.kubernetes.io/ kubernetes-xenial main" >> /etc/apt/sources.list.d/kubernetes.list

//由于这个官方镜像地址需要翻墙，国内是连接不上的，故可以改为国内的镜像地址
echo "deb https://mirrors.aliyun.com/kubernetes/apt/ kubernetes-xenial main" | sudo tee /etc/apt/sources.list.d/kubernetes.list

sudo apt-get update

安装kubeadm及kubelet等工具

sudo apt-get update
sudo apt-get install -y kubelet kubeadm kubectl
# 保持版本，取消自动更新
sudo apt-mark hold kubelet kubeadm kubectl

 二、用kubeadm创建Cluster

sudo kubeadm init --image-repository registry.aliyuncs.com/google_containers --kubernetes-version v1.19.1 --pod-network-cidr=10.240.0.0/16 --ignore-preflight-errors=Swap --ignore-preflight-errors=NumCPU

下图为执行成功的结果：

三、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

echo "source <(kubectl completion bash)" >> ~/.bashrc

kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml

kubectl apply -f https://docs.projectcalico.org/v3.3/getting-started/kubernetes/installation/hosted/canal/rbac.yaml

kubectl apply -f https://docs.projectcalico.org/v3.3/getting-started/kubernetes/installation/hosted/canal/canal.yaml
