Question

Your team maintains a Helm chart for an internal payment service. You release a new chart that adds a configurable readinessProbe template and fixes an indentation bug in a template, but the packaged application container image remains exactly the same as the previous release. Which field in Chart.yaml should you increment to correctly reflect this change according to Helm conventions?

Accepted Answer

The 'version' field, because the chart packaging itself changed even though the app did not

Answer

The 'appVersion' field, because any change to the chart implies a new application version

Answer

Both 'version' and 'appVersion' must always be incremented together on every release

Answer

The 'kubeVersion' field, since template changes affect Kubernetes compatibility
