Configuring Subcharts from Parent Values

Passing values down by subchart name.

Subcharts Have Their Own Values

Each subchart ships its own values.yaml with its own defaults. From your parent chart you can reach in and override those settings.

Nest Under the Subchart Name

To configure a subchart, add a key in your parent values.yaml matching its name. Everything under that key flows into the subchart.

postgresql:
  auth:
    username: appuser
    database: appdb
