/create-chart - Create Helm Chart

Generate a Helm chart for deploying an application to Kubernetes.

Steps

1. Ask the user for the application name, type (web app, API, worker, cronjob), and container image 2. Create the chart directory structure with `helm create` 3. Configure Chart.yaml with name, version, appVersion, and description 4. Customize the Deployment template: replicas, resources, probes, env vars 5. Configure the Service template: type (ClusterIP, LoadBalancer, NodePort), ports 6. Add Ingress template with host, path, TLS configuration 7. Create ConfigMap and Secret templates for application configuration 8. Add HorizontalPodAutoscaler template with CPU/memory scaling rules 9. Configure PodDisruptionBudget for high-availability deployments 10. Set up ServiceAccount with appropriate RBAC permissions 11. Define values.yaml with sensible defaults for all configurable parameters 12. Validate the chart with `helm lint` and `helm template`

Rules

• Always include resource limits and requests in deployment templates
• Configure liveness and readiness probes for all containers
• Use values.yaml for all configurable parameters; do not hardcode in templates
• Include pod anti-affinity rules for high-availability deployments
• Set security context: non-root user, read-only filesystem, drop capabilities
• Use chart hooks for database migrations or pre-deployment checks
• Pin container image tags; never use 'latest' in production values
