Helm Template Syntax Reference

A cheat sheet for Helm templates: values, flow control and Sprig functions.

Runs entirely in your browser - nothing is uploaded and no cluster connection is made. 
The text export of the filtered reference appears here.

About Helm Template Syntax Reference

Helm templates combine Go text/template with Sprig functions. This cheat sheet collects the syntax you use most: reading values, flow control with range/if/with, reusable named templates with define/include, and the Sprig helpers toYaml, default, required, tpl, quote and indent.

Use the filter to jump to a construct. Everything is static and runs in your browser.

Features

  • Values - {{ .Values.x }}
  • Flow - range, if, with, block.
  • Named templates - define / include / template.
  • Sprig - toYaml, nindent, default, required, tpl, quote.
  • Filter - search the cheat sheet.

How to Use

  1. Read the entries grouped by construct.
  2. Filter with the search box to find a function.
  3. Copy the whole reference if needed.

Examples

range loops a list; if guards a block; include renders a named template; toYaml | nindent inlines a map.

Benefits

  • Fast lookup - common syntax in one place.
  • Accurate - real Helm/Go template constructs.
  • Local - nothing uploaded.
  • Exportable - copy or download.

Frequently Asked Questions

What is this?
A compact Helm template cheat sheet: how to read values, control flow (range, if, with), named templates (define and include), and the Sprig functions people reach for most.
What is the difference between template and include?
include renders a named template and returns its output as a string (so you can pipe it), while template renders inline and cannot be piped. Prefer include.
When do I use default vs required?
default supplies a fallback when a value is empty; required fails the render with a message if the value is empty - use it for mandatory values.
What does toYaml do?
It serializes a value (often a map from values.yaml) into YAML so you can inline it into a manifest, typically piped to nindent.
Does this connect to a cluster?
No. It is a static reference; nothing is uploaded or fetched.
