Set value in dependency of Helm chart

Question

I want to use the postgresql chart as a requirements for my Helm chart.

My requirements.yaml file hence looks like this:

dependencies:
  - name: "postgresql"
    version: "3.10.0"
    repository: "@stable"

In the postgreSQL Helm chart I now want to set the username with the property postgresqlUsername (see https://github.com/helm/charts/tree/master/stable/postgresql for all properties).

Where do I have to specify this property in my project so that it gets propagated to the postgreSQL dependency?

Answer 1

As described in https://v2.helm.sh/docs/chart_template_guide/#subcharts-and-global-values , in your parent (ie not the dependency) chart's values.yaml file, have a section that contains

postgresql:
  postgresUsername: ....
  postgresPassword: ....
  ...

That is, all values under the postgresql key will override the child ( postgresql ) chart's values.yaml values. Note that if you have aliased the postgresql dependency chart to another name in your requirements.yaml , you should use that other name instead of postgresql .

edit: The corresponding article in v3 is here https://helm.sh/docs/chart_template_guide/subcharts_and_globals/
