[FEATURE REQUEST] wildcard domain on Ingress Operator - use case

[ionutz89]

It will be useful if we can pass on the ingress operator the secretName on config.yaml.

At the moment it only creates a new cert from cert issuer like the cert-manager provider.

We have a case where we are using only wildcard domain and we have to edit manually each Ingress to use the same secretName like an example below.

apiVersion: openfaas.com/v1alpha2
kind: FunctionIngress
metadata:
  name: nodeinfo
  namespace: openfaas
spec:
  domain: "nodeinfo.myfaas.club"
  function: "nodeinfo"
  ingressType: "nginx"
  tls:
     enabled: true
     secretName: same-cert-secret

If it is a workaround like to automate this bit, it will very useful to know.

What do you think about it?
