helm-pack

This is a helm plugin designed to be able to set properties before packaging. it has the same flags as the helm package command except that you can define properties when packaging (helm pack myfolder --set myprop=myval)

Description

The goal of this helm plugin is to be able to set properties before packaging. Suppose that you have the following pipeline:

• write code for you app
• push your code to your repo which will build a docker image automatically tagged (suppose the tag is mytag1234)
• after building your image you automatically trigger another pipeline associated to the helm chart repo which contains a values.yaml with some unset value

deployment:
 name: "deployment_name"
 replicas: 1
 version: imageversion  <= UNSET VALUE
  container:
  image: "my.repo.url/path/image"
  configMapRef:
   name: "deployment-config"
  limits:
   memory: "1Gi"
   cpu: "1000m"
  request:
   memory: "500Mi"
   cpu: "500m"
  imagePullPolicy: "Always"  

• then in order to create our helm package according to the docker image previously built we need to inject the version value (mytag1234) during the packaging process. so we won't have to make helm install mypackage --set deployment.version=mytag1234 during the installation. but instead helm package . --set deployment.version=mytag1234 so that way we during the installation we just have to execute helm install mypackage knowing that the version dependency has been resolved earlier during the packaging process.

IMPORTANT NOTE: this is still a work in progress but if you have any issues/remarks let me know.

Install

The plugin will be downloaded from github

Usage

the same options of the package command apply here with the possibilty to set property
