Summary

Converts apps/jenkins/ (flat YAML files) → helm/jenkins/ (proper Helm chart).

Chart structure

helm/jenkins/
├── Chart.yaml                  # chart metadata + version
├── values.yaml                 # ALL tuneable settings in one place
├── argocd-application.yaml     # ArgoCD app — points to this chart
└── templates/
    ├── _helpers.tpl             # shared labels, name helpers
    ├── namespace.yaml
    ├── rbac.yaml                # ServiceAccount + ClusterRole + CRB (toggled by rbac.enabled)
    ├── pvc.yaml                 # PVC (toggled by persistence.enabled)
    ├── deployment.yaml          # initContainers toggled by values
    ├── service.yaml
    └── ingress.yaml             # toggled by ingress.enabled

What changed vs flat YAML

Before	After
Hardcoded `jenkins.thedevops.dev` in ingress.yaml	`{{ .Values.ingress.host }}`
Hardcoded `longhorn` storage class	`{{ .Values.persistence.storageClass }}`
Hardcoded `20Gi` PVC size	`{{ .Values.persistence.size }}`
Hardcoded `lts-jdk17` image tag	`{{ .Values.image.tag }}`
No way to disable ingress	`ingress.enabled: true/false`
No way to disable RBAC	`rbac.enabled: true/false`
No way to disable initContainers	`initContainers.installDocker.enabled: true/false`

How to deploy after merge

# Via ArgoCD (GitOps — recommended)
kubectl apply -f helm/jenkins/argocd-application.yaml

# Direct Helm install (for testing)
helm install jenkins ./helm/jenkins -n jenkins --create-namespace

# Helm dry-run to verify templates render correctly
helm template jenkins ./helm/jenkins

Original flat YAML in apps/jenkins/ is kept untouched

Migrate when ready — no forced cutover.
