My problem is that my traefik ingress controller in my kubernetes cluster does response 404 page not found over http, BUT over https I get the real response from the service.
This happened after I added the TLS section to IngressRoute.
This is my IngressRoute:
apiVersion: traefik.containo.us/v1alpha1
kind: IngressRoute
metadata:
name: example-backend
namespace: example
spec:
entryPoints:
- web
- websecure
routes:
- match: Host(`api.example.com`)
kind: Rule
priority: 10
services:
- name: example-backend-service
port: 80
tls:
secretName: tls-secret # I'm using my own certificate, not Let's EncryptWhy I don't get the real/same response like https does?
As the TLS applies on a router, you cannot have only one IngressRoute to handle the 2 cases.
apiVersion: traefik.containo.us/v1alpha1
kind: IngressRoute
metadata:
name: example-backend
namespace: example
spec:
entryPoints:
- websecure
routes:
- match: Host(`api.example.com`)
kind: Rule
priority: 10
services:
- name: example-backend-service
port: 80
tls:
secretName: tls-secret
