Helm-Template Standalone

This is a standalone Helm template utility to help chart developers debug their charts.

Based on Helm template plugin by technosophos and Helm source.

It works like helm install --dry-run --debug, except that it runs locally, has more output options, and is quite a bit faster.

Usage

Render chart templates locally and display the output.

This does not require Helm or Tiller. However, any values that would normally be looked up or retrieved in-cluster will be faked locally. Additionally, none of the server-side testing of chart validity (e.g. whether an API is supported) is done.

$ helm-template [flags] CHART

Flags:

  -x, --execute stringArray      only execute the given templates
  -h, --help                     help for helm-template
  -n, --namespace string         namespace (default "NAMESPACE")
      --notes                    show the computed NOTES.txt file as well
  -o, --output-dir string        store the output files in this directory
  -r, --release string           release name (default "RELEASE-NAME")
      --set stringArray          set values on the command line
      --set-string stringArray   set STRING values on the command line
  -f, --values valueFiles        specify one or more YAML files of values (default [])
  -v, --verbose                  show the computed YAML values as well

Install

Get binary files or install from source:

$ go get -u github.com/n0madic/helm-template

The above will fetch the latest release of helm-template and install it.

Developer (From Source) Install

If you would like to handle the build yourself, instead of fetching a binary, this is how recommend doing it.

First, set up your environment:

• You need to have Go installed. Make sure to set $GOPATH
• If you don't have Glide installed, this will install it into $GOPATH/bin for you.

Clone this repo into your $GOPATH. You can use go get -d github.com/n0madic/helm-template for that.

$ cd $GOPATH/src/github.com/n0madic/helm-template
$ make bootstrap build

That last command will skip fetching the binary install and use the one you built.
