Dashboard fails when accessed through kube proxy

[vladimirtiukhtin]

Welcome!

• Yes, I've searched similar issues on GitHub and didn't find any.
• Yes, I've searched similar issues on the Traefik community forum and didn't find any.

What did you do?

I run traefik with insecure dashboard (I however do not expose traefik port through a load balancer). Then I do kube proxy which opens kubernetes api on some localhost port. After that I go to browser and type

http://localhost:8001/api/v1/namespaces/kube-system/services/http:traefik:api/proxy/dashboard/

which indeed opens a dashboard but with many red colored messages like the server could not find the requested resource
If Iook at the logs I can clearly see that dashboard itself cuts off the whole path to just

http://localhost:8001/api/overview

which obviously gets directed to kubernetes rather than traefik

What did you see instead?

Lots of red

What version of Traefik are you using?

2.8.8

What is your environment & configuration?

--api.insecure=true --api.dashboard=true

If applicable, please paste the log output in DEBUG level

No response

Hello @vladimirtiukhtin and thanks for your interest in Traefik,

That is because the UI is using an absolute path (i.e. /api) when sending requests to the API. To access/expose Traefik dashboard we recommend using an Ingress or k8s port forwarding as explained in the documentation.
