Grafana DataSources hard code kube-prometheus

[TimothySutton81]

What happened?
I genereated kube-prometheus using a custom jsonnet file, and set the name of prometheus to be k3s instead of defaulted k8s. I deployed everything and noticed my Grafana dashboard was not loading data sources successfully. I then realized it was still using http://prometheus-k8s.monitoring.svc:9090 url, but my service was named prometheus-k3s. I went and found the manifests/grafana-dashboardDatasources.yaml file and updated it to k3s name and data appeared in my dashboards.

Here is a section of the jsonnet config:

values+:: {
      common+: {
        namespace: 'monitoring',
      },
       prometheus+:: {

        namespaces: ["default", "kube-system", "monitoring"],
        name: 'k3s',
      },
    },

Did you expect to see some different?

Yes as describe above.

How to reproduce it (as minimally and precisely as possible):
Ran these commands to build kube-prometheus deployment

jb init # Creates the initial/empty jsonnetfile.json
jb install github.com/prometheus-operator/kube-prometheus/jsonnet/kube-prometheus@main
wget https://raw.githubusercontent.com/prometheus-operator/kube-prometheus/main/build.sh -O build.sh
chmod +x build.sh
./build.sh ims_kube_prometheus.jsonnet
