Goal

Use a small manifest as a Helm chart with values.yaml, templates, upgrade and rollback.

What Is Done

The chart renders a Deployment and a Service. Configuration such as image, replicas, service port and resources lives in values.yaml.

Typical Commands

helm lint chart/
helm template workshop-web chart/
helm upgrade --install workshop-web chart/ --namespace helm-lab --create-namespace
helm status workshop-web --namespace helm-lab
helm rollback workshop-web 1 --namespace helm-lab

Validate Success

• helm lint reports no error.
• helm template renders valid Kubernetes resources.
• Helm keeps release history.

Common Mistakes

• Templates are applied directly with kubectl apply.
• Values are hard-coded into templates.
• Release name and resource name are confused.
