I have a file which will be binded to a configmap. Once I put a tpl function in it, it stops working when other lines are included in the file.
I use this helper tpl:
{{- define "call-nested" }}
{{- $dot := index . 0 }}
{{- $subchart := index . 1 | splitList "." }}
{{- $template := index . 2 }}
{{- $values := $dot.Values }}
{{- range $subchart }}
{{- $values = index $values . }}
{{- end }}
{{- include $template (dict "Chart" (dict "Name" (last $subchart)) "Values" $values "Release" $dot.Release "Capabilities" $dot.Capabilities) }}
{{- end }}testing in some.yaml:
psqlhost: {{include "call-nested" (list . "postgresql" "postgresql.fullname")}}
newlinekey: value
It works well if some.yaml is a standalone file. But once I bind it a configmap, it gives this error:
executing "mytestchart/templates/my-configmap.yaml" at <tpl (.Files.Glob "config/*").AsConfig .>: error calling tpl: Error during tpl function execution for "some.yaml:<br>\"name: {{include \\\"call-nested\\\" (list . \\\"postgresql\\\" \\\"postgresql.fullname\\\")}}\\r\\nnewlinekey:\n value\"\n": parse error in "mytestchart/templates/my-configmap.yaml": template: mytestchart/templates/my-configmap.yam:1: unexpected "\\" in operandOnce I remove the new line it will also work well.
edit: Configmap:
apiVersion: v1
kind: ConfigMap
metadata:
name: somename
data:
{{ tpl (.Files.Glob "config/*").AsConfig .| indent 2 }}Your template is not rendering correctly. In order to make it work you need to change the following:
Add a .tmpl suffix to the file you'd like to put to your ConfigMap, for example: some.yaml.tmpl.
Set your ConfigMap's data: to: {{- tpl ((.Files.Glob "config/*.tmpl").AsConfig) . | indent 2 }}. Add a indentation to that line also.
Your ConfigMap would than look something like this:
apiVersion: v1
kind: ConfigMap
metadata:
name: somename
data:
{{- tpl ((.Files.Glob "config/*.tmpl").AsConfig) . | indent 2 }}You can find more info with some examples here.
Please let me know if that helped.
