I can't seem to find any clear information on this anywhere, but is it possible in a Helm chart to require a third party, such as stable/jenkins, and specify configuration values?
All the examples I see are for running the helm install command directly but I would like to be able to configure it as part of my application.
In answer, @desaintmartin referred me to these documents in Slack:
This led me to find the specific part I was looking for, where the parent chart can override sub-charts by specifying the chart name as a key in the parent values.yaml.
In the application chart's requirements.yaml:
dependencies:
- name: jenkins
# Can be found with "helm search jenkins"
version: '0.18.0'
# This is the binaries repository, as documented in the GitHub repo
repository: 'https://kubernetes-charts.storage.googleapis.com/'Run:
helm dependency updateIn the application chart's values.yaml:
# ...other normal config values
# Name matches the sub-chart
jenkins:
# This will be override "someJenkinsConfig" in the "jenkins" sub-chart
someJenkinsConfig: value
