将127.0.0.1映射为/etc/hostname中的名字
vim /etc/hosts

查看安装docker 或者直接在线安装
curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun
cat << EOF | sudo tee /etc/docker/daemon.json
{
"exec-opts": ["native.cgroupdriver=systemd"],
"log-driver": "json-file",
"log-opts": {
"max-size": "100m"
},
"storage-driver": "overlay2",
"registry-mirrors": ["https://evy1apxm.mirror.aliyuncs.com"],
"insecure-registries": ["10.0.0.231:8082","10.0.0.231:8083"],
"registry-mirrors": ["http://10.0.0.231:8083"]
}

sudo systemctl daemon-reload
sudo systemctl enable docker
sudo systemctl restart docker

方法一：可以使用离线导入的方式
dpkg -i xxxx.deb
方法二：添加阿里云镜像源
apt-get update
echo y | apt-get install apt-transport-https curl ca-certificates curl gnupg lsb-release
curl https://mirrors.aliyun.com/kubernetes/apt/doc/apt-key.gpg | apt-key add -
cat << EOF | sudo tee /etc/apt/sources.list.d/kubernetes.list
deb https://mirrors.aliyun.com/kubernetes/apt/ kubernetes-xenial main
EOF
apt-get update
apt-cache show kubeadm | grep Version
方法三：添加官方仓库源
sudo curl -fsSLo /usr/share/keyrings/kubernetes-archive-keyring.gpg https://packages.cloud.google.com/apt/doc/apt-key.gpg
echo "deb [signed-by=/usr/share/keyrings/kubernetes-archive-keyring.gpg] https://apt.kubernetes.io/ kubernetes-xenial main" | sudo tee /etc/apt/sources.list.d/kubernetes.list
sudo apt-get update
apt-cache show kubeadm | grep Version
然后可使用所需的版本号直接安装
export K8S_VERSION=1.23.5-00
echo y | apt-get install kubelet=${K8S_VERSION}
echo y | apt-get install kubeadm=${K8S_VERSION}
echo y | apt-get install kubectl=${K8S_VERSION}
sudo apt-mark hold kubelet kubeadm kubectl
sudo systemctl daemon-reload
sudo systemctl enable kubelet
sudo systemctl restart kubelet
sudo systemctl status kubelet
获取所需版本号
kubeadm config images list
生成文件
cat << EOF | sudo tee /home/images.sh
#!/bin/bash
images=(
kube-apiserver:v1.23.5
kube-controller-manager:v1.23.5
kube-scheduler:v1.23.5
kube-proxy:v1.23.5

etcd:3.5.1-0
coredns:v1.8.6
)
for imageName in ${images[@]} ; do
docker pull registry.cn-hangzhou.aliyuncs.com/google_containers/$imageName
docker tag registry.cn-hangzhou.aliyuncs.com/google_containers/$imageName k8s.gcr.io/$imageName
done
EOF
chmod +x /home/images.sh && ./home/images.sh

##flannel的网络设置要与init里的pod网络设置一致，否则后面能ready但是不能通信。
kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml
cat /run/flannel/subnet.env
日志
Forwarding loop detected in "." zone. Exiting. See https://coredns.io/plugins/loop##troubleshooting
则执行
1.kubectl edit cm coredns -n kube-system
2.delete ‘loop’ , save and exit
3.kubctel delete pod xxxxx -n kube-system
复制加入节点
假如你目前不是root，则执行以下命令
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
假如你目前是root，则
export KUBECONFIG=/etc/kubernetes/admin.conf
或者
echo "export KUBECONFIG=/etc/kubernetes/admin.conf" >> ~/.bash_profile
source ~/.bash_profile
source <(kubectl completion bash)
echo "source <(kubectl completion bash)" >> ~/.bashrc
