Q24 Helm Generator

Invoke when:

• Starting Task 5 of the q24 assignment
• User asks to create Kubernetes manifests or Helm chart
• Setting up application deployment to k3d

Trigger Phrases

• "Generate Helm chart for Task 5"
• "Deploy Task API to Kubernetes"
• "Create k8s manifests with Helm"

Execution Flow

Stage 1: Gather Requirements

# Check cluster status
kubectl cluster-info
kubectl get nodes

# Verify Docker image exists
# Should be built in Task 3, pushed in Task 4
echo "Expected image: ghcr.io/<username>/q24devops:latest"

# Get available storage classes
kubectl get storageclass

Information to collect:

• Image repository and tag from Task 4
• Environment configurations (dev/acc/prd differences)
• Resource limits for k3d cluster
• PostgreSQL version preference (default: 15-alpine)
• Storage requirements (default: 1Gi for local)

Stage 2: Generate Chart Structure

Create Helm chart in k8s/taskapi/:

k8s/taskapi/
├── Chart.yaml
├── values.yaml
├── values-dev.yaml
├── values-acc.yaml
├── values-prd.yaml
