Question

You are deploying an application named 'billing' with Helm. The chart's values.yaml sets 'replicaCount: 2'. Your team maintains an environment file prod-values.yaml that sets 'replicaCount: 4'. During a hotfix rollout you run: helm install billing ./billing-chart -f prod-values.yaml --set replicaCount=6. After the release completes, how many replicas will the Deployment be configured with, and why?

Accepted Answer

6 replicas, because --set has the highest precedence and overrides both values.yaml and the -f file

Answer

4 replicas, because the -f file is applied last and overrides both the chart default and --set

Answer

2 replicas, because the chart's built-in values.yaml always takes priority over runtime overrides

Answer

The install fails because you cannot combine -f and --set in a single helm command
