How does one configure a ingressroute to expose a Stateful set pods dns entry trying to expose a HA Prometheus write endpoint
Have the following services:
prometheus-prometheus-stack-kube-prom-prometheus-0.prometheus-operated.prom:9090/
prometheus-prometheus-stack-kube-prom-prometheus-1.prometheus-operated.prom:9090/

And want to be able to forward paths to the correct instance:

- kind: Rule
    match: PathPrefix(`/prometheus-a/api/v1/write`)
    services:
    - kind: Service
      scheme: http
      name: {{ what can i put here }}
      port: 9090
- kind: Rule
    match: PathPrefix(`/prometheus-b/api/v1/write`)
    services:
    - kind: Service
      scheme: http
      name: {{ what can i put here }}
      port: 9090```

@owenhaynes did you ever get this sorted out? I'm looking to do something similar.

I appreciate the help!
