kubernetes 1.20.0二进制包+flannel部署
二进制、镜像准备：
master：
kubeadm、kubectl、kubelet+cni二进制集合
kube-controller-manager
kube-scheduler
kube-apiserver
kube-proxy
pause
coredns
flannel
etcd
node001：
kubeadm、kubectl、kubelet+cni二进制集合
kube-proxy
flannel
pause
etcd
配置文件准备：
1、kubeadm配置文件
/usr/lib/systemd/system/kubelet.service.d/10-kubeadm.conf
2、kubelet配置文件
/usr/lib/systemd/system/kubelet.service
3、cni 二进制拷贝至opt/cni/bin目录下/master和node节点 flannel里面的command都有到该目录下找网络相关二进制
环境清理
2 iptables -F && iptables -X && iptables -Z && iptables -L&&systemctl stop iptables&&systemctl status iptables
3 swapoff -a;sed -i -e /swap/d /etc/fstab
4 sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
5 setenforce 0
6 rm -rf /etc/kubernetes
7 rm -rf $HOME/.kube/config
8 rm -rf /etc/cni/net.d
9 rm -rf /var/lib/etcd
10 rm -rf /root/.kube/config
kubeadm reset
kubeadm reset
部署流程：
master：
kubeadm init --config=/home/init_default.yaml
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
export KUBECONFIG=/etc/kubernetes/admin.conf
kubectl create -f kube-flannel.yml
node001：
kubeadm join 10.2.5.141:6443 --token abcdef.0123456789abcdef \
--discovery-token-ca-cert-hash sha256:c94ac493be4982df3f77baf9aae56d873ffc7371d8585b838361fe93f9c6fe3b
部署结果：
