Overview

A named template, also known as a partial, sub-template or embedded template, is a fragment of text that is declared in one file and then rendered in-line into another template, usually defined in a different file, every time it is invoked with the template action or the include function. A sub-template is declared with the define action. A sub-template name has a name, declared when the sub-template is defined. The sub-template body may contain action and function declaration, which will be rendered when the enclosing template is rendered.

Actions

define

The 'define' action is used to declare the name and the content of the sub-template:

{{- define "mychart.mysubtemplate" }}
labels:
  color: blue
  date: {{ now | htmlDate }}
{{- end }}

template

The 'template' action renders the specified sub-template, with the given scope, in the enclosing template.

kind: ConfigMap
metadata:
  name: test-cm
  {{- template "named-template-with-define.subtemplate-a" . }}
