1. 关swap
swapoff -a
/etc/fstab
配置hosts
2. 配置docker groupdriver
vi /etc/docker/daemon.json
{
"exec-opts": ["native.cgroupdriver=systemd"],
"registry-mirrors": ["https://b9pmyelo.mirror.aliyuncs.com"]
}
systemctl restart docker
3.下载
apt-get update && apt-get install -y apt-transport-https
curl curl https://mirrors.aliyun.com/kubernetes/apt/doc/apt-key.gpg | apt-key add -
cat >> /etc/apt/sources.list.d/kubernetes.list << EOF deb https://mirrors.aliyun.com/kubernetes/apt/ kubernetes-xenial main EOF
apt-get update apt-get install -y kubelet=1.23.1-00 kubeadm=1.23.1-00 kubectl=1.23.1-00
4 创建master
kubeadm init \
--image-repository registry.aliyuncs.com/google_containers \
--kubernetes-version v1.23.1 \
--service-cidr=10.96.0.0/12 \
--pod-network-cidr=10.244.0.0/16 \
--ignore-preflight-errors=all
mkdir -p /root/.kube
cp -f /etc/kubernetes/admin.conf /root/.kube/config
chown 0:0 /root/.kube/config
kubectl apply -f kube-flannel.yml
kubectl taint node myang-computer node-role.kubernetes.io/master:NoSchedule-
ps： flannel默认10.244.0.0/16 calico默认192.168.0.0/16
5.加入node
去master上查看token和hash值
kubeadm token list
kubeadm token create
openssl x509 -pubkey -in /etc/kubernetes/pki/ca.crt | openssl rsa -pubin -outform der 2>/dev/null | openssl dgst -sha256 -hex | sed 's/^.* //'
node上执行
kubeadm join 20.20.41.149:6443 --token 7lzpv4.wdy86sf6az9h239f --discovery-token-ca-cert-hash sha256:24c2b2cca73ae4a143943fcd785d57ca700776c20cd4501fe56697a3f254d3d8
