No displayed k8s ingress information on traefik ui

[ian]

I use k8s ingress with traefik , it's work fine , but no information about router rule information display on the traefik ui .

Any ideas?

Hi @ian,
Thanks for your interest in Traefik.

It is probably because Traefik is not able to load the dynamic configuration from your ingress.
Did you enable providers.kubernetesingress in your static configuration?

@ian, is your configuration working now?

I have a similar configuration which is working as expected.

Hi Maxence ;

Thanks

I use microk8s , default use nginx , when i disable nginx ,the traefik ui is work

but when i use 80 port run web site service , it's response reject connect , if i input node port on url , it's work .

I don't know what is wrong .

http://172.16.3.204 , response reject connect and in traefik pod log not found any request log.

http://172.16.3.204:30090 , it's map to my web site service and work fine , in traefik pod log can found the request log.

My traefik.yaml :

My Web yaml

i found the solution，in create traefik-controller yaml must set hostNetwork: true .

Thanks
