我是 用的 archlinux 然后 跑的 virtualbox ，创建了3 个debian 虚拟机 master(192.168.2.100) node1(192.168.2.101) node2(192.168.2.102) ,master 给4g内存 ，别的都给2 g 内存 ，互相 也能ping 通

因为 kube-flannel 没有下载成功，导致集群中没有网络组件，一直处于 NotReady 状态。
你可以手动的安装下 kube-flannel。
bash kainstall-debian.sh add --network flannel
bash kainstall-debian.sh add --ingress nginx
bash kainstall-debian.sh add --ui dashboard

谢谢你 ，不过我 用 你的 离线版 debian 压缩包安装 成功啦 ！

我在问一个问题， 就是 我 跑成功了， 我在 node1 上面跑了个 pod (一个nodejs 的网页 )，然后给映射了端口 8090
kubectl port-forward pod-name 8090:8080
然后在 node1 上面 执行 curl http://localhost:8090 是 可以 访问 的 ，但 是 我在 宿主机 上面 执行 curl http://192.168.2.101:8090 就会报 port 8090 after 0 ms: 拒绝连接了
外部 网络 就 不能访问 我这个 服务端口了 ，ping 192.168.2.101 是可以 的 ，防火墙 我也 根本没有开，我用
kubectl get pod -o wide 命令 发现 这个pod 的 ip 是 10.244.1.8
root@k8s-master-node1 ~# kubectl get pod -o wide

test-k8s-8598bbb8c6-f5dc8 1/1 Running 0 52s 10.244.1.9 k8s-worker-node1 <none> <none>
是因为 网段不同 导致 不能访问么？ 宿主机 和 虚拟机之间 是 192.168.2.xxx 网段 ，然后 k8s 又自己 造了 10.244.x.xxx网段
（刚学习k8s 请教 一下 ……）

kubectl port-forward 只能在本地访问，可以使用svc的nodeport，或者ingress来暴露服务到外部
