本地主机的 Kube.netes Traefik 入口规则

Question

I am trying to connect to traefik dashboard to localhost. My manifest below will bring up the localhost:port but I only get 404 errors. Now sure how to set the ingress to work locally. The base code was set up to run on AWS NLB, I am trying to setup this to run locally. This manifest below contains the deployment and service for the traefik Kube.netes install.

Answer 1

Your IngressRoute points to the dashboard service in namespace 'kube-system', but the traefik dashboard service is deployed in namespace 'traefik'. Therefore the route is not working, leading to the 404 in traefik.
