1) Why Helm Exists

Imagine your full-stack app in Kubernetes:

• frontend-deployment.yaml
• backend-deployment.yaml
• mongodb-deployment.yaml
• services.yaml
• ingress.yaml
• configmap.yaml
• secrets.yaml

Now imagine:

• You want 3 environments (dev, staging, prod)
• Different image tags per environment
• Different replica counts
• Different DB credentials
• Different Ingress hosts

Without Helm:

• You duplicate YAML files
• Or maintain multiple folders
• Or manually edit values every time
