yum install -y kubelet kubeadm kubectl --disableexcludes=kubernetes 安装管理命令
由于安装镜像根据官方更新的定，所以安装时不一定是1.15版本的工具
systemctl enable kubelet && systemctl start kubelet
kubeadm config images list 列出版本需求的软件
kubeadm config print init-defaults > kubeadm.conf
vim kubeadm.conf
registry.aliyuncs.com/google_containers国内镜像可以上阿里云搜软件
kubeadm config images pull --config kubeadm.conf 批量下载

注意的是–pod-network-cidr在使用flannel时，设置为10.244.0.0/16，如果是calico应该设置为192.168.0.0/16
如果你是物理节点在此网段内，需要修改为其他值，比如我使用calico时改为172.16.0.0/16。#这个我没搞懂为啥

kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml 部署flannel网络
echo 1 > /proc/sys/net/ipv4/ip_forward
echo 1 > /proc/sys/net/bridge/bridge-nf-call-iptables
kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/k8s-manifests/kube-flannel-rbac.yml 部署node节点后操作 就会变成ready
vim kube-flannel.yml 改配置线下下来 这个不用改应为不是多网卡
containers:
- name: kube-flannel
image: quay.io/coreos/flannel:v0.11.0-amd64
command:
- /opt/bin/flanneld
args:
- --ip-masq
- --kube-subnet-mgr
- --iface=ens33
2.装dashborad和处理coresdns不通的问题
3.coresdns内核版本问题yum -y install yum install -y kernel reboot
4.

kubernetes-dashboard.yml
改成相应的版本1.10.1我这里是 这个配置文件网上找就可以 配置文件版本要对的上下载的ui版本
kubectl apply -fkubernetes-dashboard.yml
5.最后查看端口 kubectl get svc --all-namespaces
kubectl get pods -n kube-system
