Add Dependencies to a Helm Chart

Add dependencies to a Helm chart

In this lesson, we’ll refactor the generic app chart and see the pros and cons each approach has. We’ll start from something simple: We define the postgres chart as a dependency to the app chart, so instead of running a separate command to install the PostgreSQL database we can specify it in values.yaml.

To add such a dependency we need to modify the Chart.yaml file by adding the dependencies property:

It’s a list of objects for which we need to specify the following:

• name: This is the original name of the chart.
• version: This is the version of the chart (it’s version, not appVersion, the field from Chart.yaml).
