Include a helm template in yaml file, removing quotes - kubernetes

Question

This is a snippet from helpers.tpl of my helm chart:
{{/*
Pod-specific labels - added to pod template only
Adding a revision label to the pod will cause it to restart every time the chart is deployed.
*/}}
{{- define "app.podLabels" -}}
helm-revision: {{ .Release.Revision | quote }}
{{- end }}
Including it in pod labels like this:
labels:
{{- include "app.podLabels" . | nindent 8 }}
The result would be as shown below. The quotes around 1 is required because Kubernetes accepts string labels only.
labels:
helm-revision: "1"
I need to use the same template for an init container, replacing the : with = like this:
args:
- "pod"
- "-l {{ include "app.podLabels" . | replace ": " "=" }}"
But the output would be an incorrect yaml:
args:
- "pod"
- "-l helm-revision="1""
with error:
error converting YAML to JSON: yaml: line 34: did not find expected '-' indicator
What I actually want is something like this, that doesn't contain quotes around 1:
args:
- "pod"
- "-l helm-revision=1"
How can I achieve this?

Answer 1

This can be achieved by replacing " with nothing ( In effect, removes "). Escaping the quotes using \ character would be needed.
Also adding a replace function to remove newlines and add , as a separator between labels. This would be helpful if more than one pod-specific label is present. But make sure this will work in your case when rendering the template.
args:
- "pod"
- "-l {{ include "app.podLabels" . | replace ": " "=" | replace "\n" ", " | replace "\"" "" }}"
