Is there a way to support multiply ingress classes in one cluster

[raighne-datature]

let's say I have two ingress classes "kong" and "ingress" in my cluster. is there any way to support them both?

Ingress example 1:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: test-kcert1
  labels:
    kcert.dev/ingress: "managed"
  annotations:
    kcert.dev/ingressClassName: "kong"

Generated KCert-ingress:

spec:
  ingressClassName: kong

Ingress example 2:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: test-kcert2
  labels:
    kcert.dev/ingress: "managed"
  annotations:
    kcert.dev/ingressClassName: "ingress"

Generated KCert-ingress:

spec:
  ingressClassName: ingress

Good question. I think the best way to do this would to run two instances of KCert that run in parallel. This should be doable be telling each instance of KCert to only operate on ingresses with a certain label.

I don't remember at the moment if this is configurable today. If it isn't, it should be a fairly simple fix. I think I could find time to catch on this and other things next month.

understood, I just look through the documentation, I cannot find the way to configure it now. And I think I can help with it.

May I say the way to deploy Kcert will not change, but when we set env CHALLENGEINGRESS__CLASSNAME, we should add a new label like

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: test-kcert2
  labels:
    kcert.dev/ingress: "managed"
    kcert.dev/ingressClassName: "ingress"

and in KCert, it will find this label by env.

That sounds great!
