安装K8S
1) 添加 Kubernetes 仓库
$ vi /etc/yum.repos.d/kubernetes.repo
[kubernetes]
name=Kubernetes
baseurl=https://packages.cloud.google.com/yum/repos/kubernetes-el7-x86_64
enabled=1
gpgcheck=1
repo_gpgcheck=1
gpgkey=https://packages.cloud.google.com/yum/doc/yum-key.gpg https://packages.cloud.google.com/yum/doc/rpm-package-key.gpg
2) 安装 kubeadm, kubelet, 和 kubectl,三台机器都要安装
$ sudo yum install -y kubelet-1.20.10-0 kubeadm-1.20.10-0 kubectl-1.20.10-0
3) 初始化master节点
$ sudo kubeadm init --pod-network-cidr=10.244.0.0/16
4) 安装成功
5) 设置kubectl配置文件
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
6) 安装 Pod 网络插件
$ sudo kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml
7) 加入node工作节点
在node1和node2运行
从主节点复制 kubeadm join 命令
$ kubeadm join 192.168.11.139:6443 --token 8u9xi5.eaffhbpk6yrsr52f \
--discovery-token-ca-cert-hash sha256:883c0637ffc0825b79f6fb40c1c9473775b564b3532f5f3a64332cdxxxxx
master节点查看
$ kubectl get nodes
