I have a parent helm chart which creates service:

controlplane-dktkocdx-kong-cluster

I gave it the label:

<http://konghq.com/service=cluster|konghq.com/service=cluster>

I can find the service name with the command:

kubectl get services -nkong --selector '<http://konghq.com/service=cluster|konghq.com/service=cluster>' -ojsonpath='{.items[*].metadata.name}'

I need this name before I render a child helm chart so I can inject the service name. How do I write a const which looks up this name so I can use it in the child chart?
