I have used almost all possible ways to render the helm template. But now I am out of ideas and seeking help:

values.yaml:

rollout:
  namespace: xyz
  project: default
  baseDomain: "stage.danger.zone"
  clusterDomain: cluster.local

manifest.yaml

apps:
  certmanager:
    source:
      repoURL: 'https://artifactory.intern.example.io/artifactory/helm'
      targetRevision: 0.0.6
      chart: abc
    helm:
      releaseName: abc
    values:
      global:
        imagePullSecrets:
          - name: artifactory
      baseDomain: "{{ .Values.rollout.baseDomain }}"

When I try to render the template using the below command in my main.yaml file that will produce the final result:

values: {{- tpl (toYaml $appValue.values | indent 6) $ }}

Expected result:

baseDomain: stage.danger.zone (without quotes)

What I am getting is:

baseDomain: 'stage.danger.zone'

If I try to remove the double quotes from: baseDomain: "{{ .Values.rollout.baseDomain }}", I get the following error:

[debug] error converting YAML to JSON: yaml: invalid map key: map[interface {}]interface {}{".Values.baseDomain":interface {}(nil)}

Any help or ideas to achieve the same?

This is an expected behaviour by YAML.

One dirty and bad hack would be

values: {{- tpl (toYaml $appValue.values | fromYaml | toYaml | indent 6) $ }}

and then you will not see the single quotes.

However, This is not a problem at all even if you have ' single quotes in your value. You can include this variable for example something like this below:

      hosts:
        - host: some-gateway.{{ .Values.rollout.baseDomain }}
          serviceName: gateway
          servicePort: 8080
          path: /

Then it will show you your variable value without ' single quotes.

Example rendered output:

        hosts:
        - host: some-gateway.stage.danger.zone
          path: /
          serviceName: gateway
          servicePort: 8080
