GKE Ingress config requires a single host with multiple paths

[BennetVellaExient]

If you want to configure GKE Ingress with multiple backends for the same host, you must have a single rule with a single host and multiple paths. Otherwise, the GKE ingress controller provisions only one backend service

Source: https://cloud.google.com/kubernetes-engine/docs/concepts/ingress#multiple_backend_services

But the helm ingress.yaml creates multiple hosts:

windmill-helm-charts/charts/windmill/templates/ingress.yaml

Line 25 in 4a71fc7

- host: {{ .Values.windmill.baseDomain | quote }}

Can confirm that combining the paths under a single host correctly updated the load balancer to map properly

So as a practical example, what I was getting by default helm configuration:

 spec:
    rules:
    - host: windmill.blabla
      http:
        paths:
        - backend:
            service:
              name: windmill-lsp
              port:
                number: 3001
          path: /ws/
          pathType: Prefix
    - host: windmill.blabla
      http:
        paths:
        - backend:
            service:
              name: windmill-app
              port:
                number: 8000
          path: /
          pathType: Prefix

For GKE, the expected setup should be as follows:

 spec:
    rules:
    - host: windmill.blabla
      http:
        paths:
        - backend:
            service:
              name: windmill-lsp
              port:
                number: 3001
          path: /ws/
          pathType: Prefix
        - backend:
            service:
              name: windmill-app
              port:
                number: 8000
          path: /
          pathType: Prefix

I don't know if a shared host with multiple paths might then conflict with a different provider, but can confirm that GKE requires a single host.
