Question

Your team packages a web application as a Helm chart. The chart's values.yaml sets replicaCount: 2 and image.tag: 1.0.0. For a production release named 'web-prod', you need to deploy the same chart but with 5 replicas and image tag 2.1.0, without permanently editing the chart files. Which command achieves this in one step?

helm upgrade --install web-prod ./chart --set replicaCount=5 --set image.tag=2.1.0

helm template web-prod ./chart --set replicaCount=5 --set image.tag=2.1.0

Answer

kubectl apply -f ./chart --set replicaCount=5 --set image.tag=2.1.0

Answer
