Update helm chart with additional properties

Question

We are using the prometheus operator chart

Currently, Im creating my own values.yaml that im overriding the default values from the chart like

helm install po -f values.yaml stable/prometheus-operator -n po

There is a Grafana properties which I need to modify as the opertor come with grafana properties

https://github.com/helm/charts/blob/master/stable/prometheus-operator/values.yaml#L486

However, I want to modify properties that is not in the values.yaml of the prometheus chart and found here: https://github.com/helm/charts/blob/master/stable/grafana/values.yaml#L422 (there is a reference on the chart)

My question is assume I want to modify the client_id , what is the recommended way to do it? https://github.com/helm/charts/blob/master/stable/grafana/values.yaml#L431

You can overwrite the values of dependent charts by using the name of the dependency (which for grafana in the prometheus chart can be found here) as another key within the values.yml.

In thise case, it is just grafana and so to overwrite it in your values.yml, do it like this:

# ... config of the original prometheus chart

# overwrite grafana's yaml by using the dependency name
grafana:
  grafana.ini:
    auth.github:
      client_id: 'what you need to put here'
