In a Helm chart, which file do you edit to define dependencies for subcharts?

• A. chart.yaml
• B. values.yaml
• C. templates/dependencies.yaml
• D. requirements.yaml

Answer: (A)

Defining subchart dependencies lives in the chart’s metadata, which is Chart.yaml. You add a dependencies section there, listing each subchart with its name, version, repository, and optional alias, along with any conditions or tags. This is what tells Helm which subcharts to fetch and include when you package or install the chart. After updating Chart.yaml, you use helm dependency update to populate the charts/ directory with the specified subcharts. The values.yaml file is for providing default values to the chart and its subcharts, not for declaring dependencies. The requirements.yaml file was used in older Helm versions (Helm 2) to list dependencies, but that approach has been superseded in Helm 3. So editing Chart.yaml is the correct approach for subchart dependencies.
