Basic auth middleware with ingressroutetcp not working

Traefik Traefik v2
1

we have an IngressRouteTCP configuration for accessing kubernetes-dashboard setup as

apiVersion: traefik.containo.us/v1alpha1
kind: IngressRouteTCP
metadata:
  name: k8s-dashboard
  namespace: k8s-dashboard
spec:
  entryPoints:
    - websecure
  routes:
    - match: HostSNI(`{{ .Values.ingressRouteHost }}`)
      middlewares:
        - name: k8s-dashboard-auth
          namespace: k8s-dashboard
      services:
        - name: k8s-dashboard-kubernetes-dashboard
          namespace: k8s-dashboard
          port: 443
  tls:
    passthrough: true

the middleware referenced in the :point_up: above configuration looks like so:

apiVersion: traefik.containo.us/v1alpha1
kind: Middleware
metadata:
  name: k8s-dashboard-auth
  namespace: k8s-dashboard
spec:
  basicAuth:
    secret: k8s-dashboard-auth-secret

my end goal is to add basic auth for the k8s dashboard here.

on deploying this ingressroutetcp configuration and the related middleware config and then trying to access the dashboard, i am met with this:

18:25 $ curl https://$ingressRouteHosts
curl: (60) SSL certificate problem: unable to get local issuer certificate
More details here: https://curl.haxx.se/docs/sslcerts.html

curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and
how to fix it, please visit the web page mentioned above.

traefik logs indicate this:

the version of traefik that i am using is traefik:2.5.4

expectation:

  • executing a curl request against $ingressRouteHost should result in a 401 (indicating that the web page is behind basic auth)

what is happening:

  • i am getting http 404:
$ curl -k https://$ingressRouteHost
404 page not found

how is this being deployed:

  • via helm

Hello @prashant-warrier

Is there any specific reason why you use IngressRouteTCP in order to expose the dashboard? In my opinion, you should try to use IngressRoute because the dashboard should be reachable via HTTP.

Regarding the middleware the valid name convention is following -@provider so in your case the name of the assigned middleware should looks like this:

k8s-dashboard-k8s-dashboard-auth@kubernetescrd

You can learn more about that from that documentation: Overview - Traefik
