Configmap in helm chart user-data - kubernetes-helm

Question

This is my configmap template, it is taking data from my user-data file which is like values.yaml. I have two applications, App-A & App-B. The IPs are getting assigned by App-B, in App-A only interfaces are getting configured to which App-B is assigning IPs.
CONFIGMAP Template:
apiVersion: v1
kind: ConfigMap
metadata:
namespace: {{$namespace}}
name: {{$pod}}-configmap
data:
user-data: |
{{- $userdata := (cat $pod "-userdata"|nospace)}}
{{ $.Files.Get $userdata | nindent 4}}
App-A user-data

App-B user-data:

vnfc_vldid_ici2:

Answer 1

I don't know whether your ip data source comes from the values.yaml file or is read from other files, the above is not clear, so here are two solutions.
A: from values.yaml
values.yaml
