helm-chart-base

TODO list:

• Rework from merge approarch to nested replace or unset for clearness, basically, flow should go like that:
  • get merged dictionary on the top level
  • pass it to main override function
  • inside there are functions like base.<resourse>.override.<fieldToOverride> have to rewrite a certain field and return resource back
    • <resource> can be a Secret
    • <fieldToOverride> can be spec
  • resource should be returned to the root function
  • if high-level resource is plural, like Secrets then each unit has to be processed separately.
• Improve visibility of conditions and loops better within templates (the issue basically in indents)

Agreements:

• no lists of dictionaries are allowed in helm chart, helm lists flow breaks the merge flow in chart inheritance
• content of resources should go through tpl
• $ctx variable should be provided as-is:
  • it provides an easy way to get any path for .Values by "val" key
  • it provides an absolute context by "abs" key
  • updated values should be provided separately
