Changing k3s default ingress from 80/443 to 8080/8443

[toutas]

Is there a way to modify the setup so I am able to run awx on k3s alongside a docker-hosted traefik instance listening on 80/443? I have not been able to find a way to modify the k3s ingress for listening on 8080/8443 instead of 80/443. Currently I have modified my traefik instance in docker to listen to 8080/8443 instead, but I would prefer modifying the k3s ingress since awx is not accessed as often as my services behind traefik.

Any input is greatly appreciated.

Hi, yes, it is possible.

Create following config file.

sudo tee /var/lib/rancher/k3s/server/manifests/traefik-config.yaml <<EOF
apiVersion: helm.cattle.io/v1
kind: HelmChartConfig
metadata:
  name: traefik
  namespace: kube-system
spec:
  valuesContent: |-
    ports:
      web:
        exposedPort: 8080
      websecure:
        exposedPort: 8443
EOF

Then just wait for the pod svclb-traefik-* to be newly started (see AGE colmun).

]$ kubectl -n kube-system get pod
NAME                                      READY   STATUS      RESTARTS   AGE
...
svclb-traefik-60863cf7-s46mb              2/2     Running     0          3m46s
helm-install-traefik-m5xr6                0/1     Completed   0          3m48s

cheers, I will test this out tomorrow!

I performed the test, but it seems to just expose 8080/8443 without removing the 80/443. do I need some other modifications to remove 80/443 being listened to by the k3s traefik ingress?

it seemed to fix itself after waiting a few minutes. thank you very much!
