How to configure KUR8 to my own hosted prometheus

[pio2pio]

I have deployed KUR8 v1.0.0 to EKS v1.18 into monitoring namespace but the application was misbehaving. What is I don't know is how to point KUR8 to my prometheus service kube-prometheus-stack-prometheus:9090?

How I deployed:

kubectl -n monitoring apply -f fabric8-rbac.yaml
kubectl -n monitoring apply -f kur8-depl.yaml

# Then port-forward to access the app
kubectl -n monitoring port-forward deployment/kur8-depl 3068:3068

@pio2pio sorry for getting back to you so late. It seems like the proxy to the server isn't starting up properly. We have also included an ingress config yaml file that you can try.

Try running from the root directory:

kubectl -n monitoring apply -f kur8-ingress-srv.yaml

Let me know if this works for you. This should connect the kur8's front end to it sever within your cluster.

[mrmartan]

I tried to apply the ingress. Does not seem to help.
