The goal: Using Helm Chart pre-install hook, take a file on the filesystem, encode it and place it as a resource file (referenced by a configMap.

Questions:

• Can a Helm Chart pre-install hook access files that are not under the root chart?
• Can a Helm Chart pre-install hook modify or add a file under the Chart root?
• Other then implicitly writing the bash script inside the chart resource yaml, can the pre-install hook execute a bash script if it is placed in the chart?
