I have some data which is a multiline string. And I don't want to modify it. Now I want to prefix each one with a character

{{- define "info.geological" -}}
iWater Well Completion Reports
Anatomy of a Water Well Report
Water table Altitudes
...
{{- end -}}

What I want

Solution

  • Treat it as string in golang, split and print

    template

{{- end -}}

    template/xxx.yaml

{{- $dt := include "info.geological" . }}
{{- range ( split "\n" $dt) }}
