Common Chart Documentation

Appears in

  • .Values

Notes

This applies across all the documentation:

  • Helm tpl:
    • ❌ means that the value is not templated
    • ✅ means that the value is templated, for example instead of a hardcoded value, you can set it to {{ .Values.some.value }}. and it will be replaced by the value contained in .Values.some.value at the installation/upgrade time.
