authservice-0 not ready导致403报错

TaibiaoGuo commented 2 years ago

问题简述

您好，我使用 kubeflow 官方manifests 和您构建的manifests时 authservice-0 都出现了同样的 not ready的问题kubeflow/manifests/issue ，这导致我无法访问kubeflow 面板。

2021-10-24T03:21:48.287901796+08:00 time="2021-10-23T19:21:48Z" level=error msg="OIDC provider setup failed, retrying in 10 seconds: Get http://dex.auth.svc.cluster.local:5556/dex/.well-known/openid-configuration: EOF"

请问出现这种问题的原因是什么？方便分享一下您是如何配置 dex\istio 来实现 HTTP 访问所有服务的思路和原理呢？

官方 manifests 说明文档中使用HTTP访问所有服务的方法为需要手动设置环境变量，参见连接kf集群

我已经尝试了的方法

[x] 重装和多次安装patch
[x] kubectl port-forward
[x] 排除coreDNS解析故障

@TaibiaoGuo 看你的kubectl get pod -A 的输出结果， auth 是 running的，出问题的应该是knative 中 activator 这个服务，如果你用我的 manifest 配合 kind 安装，只需要按照 readme 访问 istio svc 的node port端口。 dex 的鉴权是 overload 在 istio 的，可以看这个文件： https://github.com/shikanon/kubeflow-manifests/blob/master/manifest1.3/008-dex-overlays-istio.yaml

@TaibiaoGuo hi,我也碰到了这个auth问题，请问，您是怎么解决的？

solve it by configure Persistent Volumes provisioner for k8s

Alvin-4550 commented 2 years ago

I also encountered this problem. Has it been solved?
