1. 安装基础环境
参考链接：使用 Kubeadm 安装 Kubernetes 集群。值得注意的是 Kubeflow 并不是对每个版本的 Kubernetes 兼容，system-requirements。

3. 查看 UI 页面
Kubeflow 通过 istio-ingressgateway 提供访问入口。由于没有 LoadBalancer ，这里将服务的 type 改为 NodePort ，执行命令：
1
|
for i in 'istio-ingressgateway'; do kubectl patch service $i -p '{"spec":{"type":"NodePort"}}' -n istio-system; done
|
查看访问端口：

kubectl get svc -n istio-system | grep istio-ingressgateway
istio-ingressgateway NodePort 10.233.27.126 <none> 15020:32305/TCP,80:31380/TCP,443:31390/TCP,31400:31400/TCP,15029:31128/TCP,15030:32594/TCP,15031:31617/TCP,15032:31969/TCP,15443:32559/TCP 1h
