Helm Release Helper

Parse "directives" from a values file comments to make common release lifecycle operations easier.
The values file's name is used as the release name (eg the release name for nginx-ingress.yaml is nginx-ingress)
Directives appear at the top of the chart like:

# CHART_REPOSITORY=https://kubernetes-charts.storage.googleapis.com
# CHART_NAME=nginx-ingress
# CHART_VERSION=0.9.5
# RELEASE_NAMESPACE=kube-system

controller:
  name: controller
  image:
...

Install

$ helm plugin install https://github.com/ceason/helm-release-helper

Usage

where [chartish] is a repository chart reference (eg stable/nginx-ingress)

helm release-helper diff [release-values.yaml]
