#yum源

cp kubernetes.repo /etc/yum.repos.d/kubernetes.repo yum clean all yum makecache
#安装docker-ce 此步骤要是master和node都执行
yum -y install yum-utils lvm2 device-mapper-persistent-data docker-ce
#启动docker
systemctl enable docker
systemctl start docker
systemctl status docker
#daemon
cp daemon.json /etc/docker/daemon.json
#重新启动

#安装kubeadm kubectl kubelet 
yum install  kubelet kubeadm kubectl --disableexcludes=kubernetes
#启动kubelet
systemctl enable kubelet
systemctl start kubelet
systemctl status kubelet
#初始化master 此步骤要是master执行

kubeadm init --kubernetes-version=$K8S_VERSION  --pod-network-cidr=10.244.0.0/16 --apiserver-advertise-address=$masteripaddr
#配置kube
mkdir -p $HOME/.kube
cp -i /etc/kubernetes/admin.conf $HOME/.kube/config chown $(id -u):$(id -g) $HOME/.kube/config
#查看节点状态
kubectl get nodes
#node
kubeadm join $masteripaddr:6443 --token $token --discovery-token-ca-cert-hash $sha256
#安装网络插件
kubectl apply -f kube-flannel.yml
#查看网络插件
kubectl get pods --namespace kube-system
#安装dashboard
kubectl apply -f kubernetes-dashboard.yaml
kubectl get pods --namespace kube-system kubectl get svc --namespace kube-system
#获取token
kubectl -n 命名空间名称(默认是kubs-system) describe secret $(kubectl -n kube-system get secret | grep 指定用户的名字(admin) | awk '{print $1}')

最后IP加端口登录dashboard,利用token登录
