[kube-prometheus-stack] Grafana switching Org adds Port 3000 in URL of Grafana

[Atomique]

Describe the bug a clear and concise description of what the bug is.

If have configured multiple Orgs and if I switch between them the Port of Grafana (:3000) gets added into the URL which leads into an browser error of course ("ERR_CONNECTION_REFUSED").

I tried to find something like prometheus.prometheusSpec.externalURL for Grafana but couldn't find it.

How Can I fix this issue?

The problem should get fixed by setting root_url in grafana.ini (Ref.). For example, with ingress host grafana.example.local and TLS:

grafana:
  grafana.ini:
    server:
      domain: grafana.example.local
      root_url: "https://%(domain)s/"

If using HTTP:

grafana:
  grafana.ini:
    server:
      domain: grafana.example.local
      root_url: "http://%(domain)s/"
      ## alternative:
      # root_url: "%(protocol)s://%(domain)s/"

Thanks a lot, that one worked. But I wonder why this is needed now. Isn't this a default value?

Edit: Sorry closed this, but would be nice to get an idea why this happened. Will close this after it!

Isn't this a default value?

No, it is not. The default root_url is set to

%(protocol)s://%(domain)s:%(http_port)s/

protocol, domain and http_port are configuration parameters of the server section with these defaults. The root URL can also be set via env variable GF_SERVER_ROOT_URL.
