Overview

A variable is a named reference to another built-in object or a constant. It is assigned and referred using the $<name> syntax. := is used as assignment operator.

{{- $relname := .Release.Name -}}
{{- $color := "green" -}}
...
data:
  release: {{ $relname }}
  color: {{ $color }}

Variables are less frequently used, as an alternative preferred construct is the named template.

Variable Scope

Variables are normally not "global". They are scoped to the block in which they are declared. However, there is one variable that is aways global: $. This variable will always point to the root context:

{{ $.Chart.AppVersion }}
