If you are using a recent version of Helm, you do not need this anymore!

helm template

helm template --help

Helm Template Plugin

This is a Helm plugin to help chart developers debug their charts. It works like

helm install --dry-run --debug

Usage

Render chart templates locally and display the output.

This does not require 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:

      --notes               show the computed NOTES.txt file as well.
      --set string          set values on the command line. See 'helm install -h'
  -f, --values valueFiles   specify one or more YAML files of values (default [])
  -v, --verbose             show the computed YAML values as well.

Install

$ helm plugin install https://github.com/technosophos/helm-template

The above will fetch the latest binary release of

helm template

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

go get -d github.com/technosophos/helm-template

$ cd $GOPATH/src/github.com/technosophos/helm-template
$ make bootstrap build
$ SKIP_BIN_INSTALL=1 helm plugin install $GOPATH/src/github.com/technosophos/helm-template

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