update
I did
kubectl get ingressroute -A
NAMESPACE NAME AGE
example example-ingress 44h
example example-ingress-route 40hand then I did
kubectl delete ingress example-ingress -n example
ingress.extensions "example-ingress" deletedand now http://example.com gives 404
but https://example.com works fine with secured cert and all?
I have a cluster where I have a simple dockerized php app that just displays “hello” on the page.
In the cluster I have installed traefik and cert-manager via their helm charts, as I am using cert-manager for lets encrypt:
https://hub.helm.sh/charts/traefik/traefik
https://hub.helm.sh/charts/jetstack/cert-manager
When I visit my domain via http it works and I can see “hello”
But when I visit my domain with https it just says “404 page not found”
Error in the traefik pod:
