Feature Request - Configuration via ConfigMap

[olib963]

I would like to be able to inject the ingress configuration that is usually gathered from static annotations instead through a configmap. I am happy to look into implementing this myself if this would be an acceptable addition. I was hoping in the ingress I could write:

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: my-ingress
  annotations:
    kubernetes.io/ingress.class: "gce"
spec:
  confgMapName: ingress
  ...

where the configmap is

apiVersion: v1
kind: ConfigMap
metadata:
  name: ingress
data:
    kubernetes.io/ingress.global-static-ip-name: "my-ip-name"
    kubernetes.io/ingress.allow-http: "false"

This would allow me to reuse the same declarative Gitops repo and simply terraform a new cluster and static IP, then have terraform inject the IP name as config.

@olib963 I'm not sure your proposal makes sense. IIUC, this would require a change to the Ingress API to support the "configMapName" field? This is definitely a non-starter.

@rramkumar1 That's ok, we could have added this functionality in an annotation instead of in the spec field e.g. gce.ingress/configmap: ingress. I have decided to go with the NGINX ingress instead, it seems a little more mature and configurable and isn't leaking resources as we rebuild. Thank you for the reply :D
