Hello ich have tried to install Kong with custom values.
A postgres Database ist running in the same namespace.
I can access the Kong-Manager WebUI, but there is not data displayed. I also tried to connect to kong but this also not worked.
I would be thankful about help 
hi @wefersmasasana
Looks like admin and manager ports are not accessible, please do port forward for Kong admin and Kong manager and try.
Example:
kubectl port-forward -n kong service/kong-kong-admin 18001:18001
kubectl port-forward -n kong service/kong-kong-manager 18002:18002
