Allow wildcard routing in host

[ashish4github]

We are implementing a SaaS based solution and need service calls for all subdomains to be routed to a same service. For example, both below service calls from browser should be touted to service.

tenanta.example.com/service1,
tenantb.example.com/ service1

How can I achieve this with single ingress resource? We tried using the host entry as *.example.com but that did not work.

As per the https://github.com/kubernetes/enhancements/blob/master/keps/sig-network/20190125-ingress-api-group.md this feature is supported in most of teh ingress controller and widely used; and thus proposed to be added to spec.

Is there any plan to support this for alb-ingress controller?

I'm interested in such a feature as well 🤞

@M00nF1sh Is there any chance this will be picked up in next release you are planning?

@ashish4github i'm taking a look at this, and i'm actually surprised if this it not supported already...

@ashish4github just tested that this is already supported.
With one tip, u should quote the host like "tenant*.example.com" :D, if you use * in yaml, you need to quote it 😄
