A Helm Chart for DRY k8s jobs

A Helm Chart for DRY job deployments

Introduction

This helm chart define a common structure to deploy kubernetes jobs.

The goal is to provide a DRY job deployment mechanism with some flexibility, to be used with some other charts orchestrating a series of jobs via dependencies, pointing to this chart, where each instance of this chart is differenciated using aliases.

The federating chart will provide the configuration for each jobs in its values file.

helm-job's Issues

[cetic/job] command + args don't work

Describe the bug
Using the command or args examples from the values.yaml does not work.

Version of Helm and Kubernetes:

version.BuildInfo{Version:"v3.5.2", GitCommit:"167aac70832d3a384f65f9745335e9fb40169dc2", GitTreeState:"dirty", GoVersion:"go1.15.7"}```

What happened:
The generated template is missing quotes

    env:
        - name: "ENV_VAR_TEST"
          value: "Test content"
        command: [/bin/sh]
        args: [-c echo 'consuming a message'; ps faxuwww; echo 'ENV_VAR_TEST='$(ENV_VAR_TEST)' != '$ENV_VAR_TEST; sleep 5]

What you expected to happen:
Add command and args as lists with quotes

env:
        - name: "ENV_VAR_TEST"
          value: "Test content"
        command: 
          - "/bin/sh"
        args: 
          - "-c"
          - "echo 'consuming a message'; ps faxuwww; echo 'ENV_VAR_TEST='$(ENV_VAR_TEST)' != '$ENV_VAR_TEST; sleep 5"

How to reproduce it (as minimally and precisely as possible):

command: ["/bin/sh"]
args: ["-c", "echo 'works'; sleep 5"]
