Question

Your team maintains a single Helm chart for a web application that must be deployed to three environments (dev, staging, prod) with different replica counts, image tags, and resource limits. You want to keep one chart while customizing each environment's deployment. What is the recommended Helm approach to achieve this?

Accepted Answer

Maintain a separate values file per environment (e.g., values-dev.yaml, values-prod.yaml) and pass the appropriate one with -f during install/upgrade

Answer

Create three independent copies of the chart, one per environment, and edit the templates directly in each copy

Answer

Hardcode the environment-specific settings into the chart's templates and use kubectl edit to change them after deployment

Answer

Store all environment differences in the Chart.yaml file and rely on Helm to detect the target environment automatically
