refactor(argocd): consolidate Applications (39→35)

Merge related Applications using multi-source pattern and PostSync hooks: 1. ingress-config ← wildcard-cert + homelab-ingress (2→1) - Both in k8s/bootstrap/ingress/, now use kustomization - Certificate deployed before Ingresses (wave 1) 2. homarr ← homarr + homarr-patches (2→1) - Added PostSync hook source (fix-probes-job.yaml) - Patches run after Helm chart deployment 3. temporal ← temporal + temporal-db-secret-sync (2→1) - Added PostSync hook source (copy-job.yaml) - DB secret sync runs after Temporal deployment 4. Removed duplicate: ingress-nginx Application - ingress-nginx-bootstrap (bootstrap) is working - Removed redundant ArgoCD-managed ingress-nginx - Eliminated duplicate DaemonSet Skipped: cert-manager + cert-manager-issuers - Wave separation needed (CRDs before Issuers) - Keep separate for safety Result: 39 → 35 Applications (-4, -10.3%) Files: - k8s/bootstrap/ingress/kustomization.yaml (updated) - k8s/argocd/apps/00-substrate.yaml (merges + removal) - k8s/argocd/apps/60-applications.yaml (merges) - CONSOLIDATION-RESULTS.md (documentation) - APPLICATION-CONSOLIDATION-PLAN.md (analysis) - GITOPS-STATUS.md (updated inventory)

 # ArgoCD Application Consolidation Plan
 ## Executive Summary
 **Current:** 39 Applications  
 **Proposed:** 32 Applications (Conservative: 35)  
 **Benefits:** Easier management, fewer Application resources, cleaner structure
 ## Phase 1: Safe & Easy Merges (Conservative - Start Here)
 These are Applications that already share the same directory and have clear parent-child relationships.
 ### 1.1 Merge: wildcard-cert + homelab-ingress → "ingress-config"
 **Current State:**
 ```
 wildcard-cert      (wave 1) → k8s/bootstrap/ingress/riotpiao-com-cert.yaml
 homelab-ingress    (wave 2) → k8s/bootstrap/ingress/ingress.yaml
 ```
 **New State:**
 ```
 ingress-config     (wave 1) → k8s/bootstrap/ingress/ (kustomization)
 ```
 **Rationale:** Both in same directory, ingress depends on cert existing
 **Implementation:**
 - Update `k8s/bootstrap/ingress/kustomization.yaml` to include both
 - Create single Application pointing to k8s/bootstrap/ingress/
 - Delete wildcard-cert and homelab-ingress Applications
 - Result: 2 → 1 Applications
 ### 1.2 Merge: homarr + homarr-patches → "homarr"
 **Current State:**
 ```
 homarr             (wave 8) → Helm chart (homarr-labs.github.io)
 homarr-patches     (wave 9) → k8s/applications/homarr/fix-probes-job.yaml
 ```
 **New State:**
 ```
 homarr (multi-source):
  - Source 1: Helm chart
  - Source 2: k8s/applications/homarr/ (patches as PostSync hook)
 ```
 **Rationale:** homarr-patches is literally a patch for homarr
 **Implementation:**
 - Modify homarr Application to use multi-source
 - Convert fix-probes-job.yaml to PostSync hook
 - Delete homarr-patches Application
 - Result: 2 → 1 Applications
 ### 1.3 Merge: temporal-db-secret-sync → temporal (as PreSync hook)
 **Current State:**
 ```
 temporal-db-secret-sync  (wave 7) → k8s/applications/temporal/db-secret-sync/
 temporal                 (wave 8) → Helm chart
 ```
 **New State:**
 ```
 temporal (multi-source):
  - Source 1: k8s/applications/temporal/db-secret-sync/ (PreSync hook)
  - Source 2: Helm chart
  - Source 3: k8s/applications/temporal/ (values)
 ```
 **Rationale:** db-secret-sync is a bootstrap job for temporal
 **Implementation:**
 - Modify temporal Application to use multi-source
 - Ensure db-secret-sync Job has PreSync hook annotation
 - Delete temporal-db-secret-sync Application
 - Result: 2 → 1 Applications
 ### 1.4 Merge: cert-manager-issuers → cert-manager (as multi-source)
 **Current State:**
 ```
 cert-manager         (wave 0) → Helm chart
 cert-manager-issuers (wave 1) → k8s/bootstrap/cert-manager/ (issuers)
 ```
 **New State:**
 ```
 cert-manager (multi-source):
  - Source 1: Helm chart
  - Source 2: k8s/bootstrap/cert-manager/ (values + issuers)
 ```
 **Rationale:** Issuers are part of cert-manager configuration
 **Implementation:**
 - Modify cert-manager Application to use multi-source
 - Keep as wave 0 (issuers can wait for CRDs to be ready)
 - Delete cert-manager-issuers Application
 - Result: 2 → 1 Applications
 **Phase 1 Result: 39 → 35 Applications (-4)**
 ---
 ## Phase 2: Logical Consolidations (Moderate Risk)
 ### 2.1 Merge: SQS Applications → "sqs-platform"
 **Current State:**
 ```
 strimzi-operator    (wave 5) → Helm chart (operator)
 kmsvc-redis         (wave 5) → Helm chart (Redis)
 kafka-cluster       (wave 6) → k8s/applications/sqs/charts/kafka-cluster/
 queue-crd           (wave 6) → k8s/applications/sqs/charts/queue-crd/
 management-service  (wave 7) → k8s/applications/sqs/charts/management-service/
 ```
 **New State:**
 ```
 strimzi-operator    (wave 5) → Keep separate (operator)
 sqs-platform        (wave 6) → k8s/applications/sqs/ (all services + CRDs)
 ```
 **Rationale:** These 4 apps work together as the SQS platform
 **Implementation:**
 - Create kustomization.yaml in k8s/applications/sqs/
 - Create single multi-source Application
 - Keep strimzi-operator separate (it's infrastructure)
 - Result: 5 → 2 Applications
 ### 2.2 Merge: authentik + iam-jobs → "authentik"
 **Current State:**
 ```
 authentik   (wave 3) → Helm chart
 iam-jobs    (wave 3) → k8s/security/iam/ (authentik helper jobs)
 ```
 **New State:**
 ```
 authentik (multi-source):
  - Source 1: Helm chart
  - Source 2: k8s/security/iam/ (helper jobs)
 ```
 **Rationale:** iam-jobs appears to be authentik-specific
 **Implementation:**
 - Verify iam-jobs are authentik-specific
 - Merge into single multi-source Application
 - Result: 2 → 1 Applications
 ### 2.3 Remove Duplicate: ingress-nginx Application
 **Current State:**
 ```
 ingress-nginx-bootstrap (wave 0, bootstrap) → Helm chart
 ingress-nginx           (wave 0, ArgoCD)    → Helm chart (DUPLICATE!)
 ```
 **New State:**
 ```
 ingress-nginx-bootstrap (wave 0, bootstrap) → Keep only this one
 ```
 **Rationale:** These are the same thing, bootstrap one is already working
 **Implementation:**
 - Delete ingress-nginx Application (redundant)
 - Result: 2 → 1 Applications
 **Phase 2 Result: 35 → 31 Applications (-4)**
 ---
 ## Phase 3: Advanced Consolidations (Consider Carefully)
 ### 3.1 Consider: Monitoring Stack
 **Current State:**
 ```
 prometheus-crds     (wave 0) → k8s/platform/monitoring/crds/
 prometheus          (wave 1) → Helm chart
 blackbox-exporter   (wave 1) → Helm chart
 ```
 **Option A:** Keep separate (CRDs must be wave 0)  
 **Option B:** Create "monitoring-stack" with prometheus + blackbox-exporter only
 **Recommendation:** Keep separate for now (CRDs are special)
 ### 3.2 Consider: Logging Stack
 **Current State:**
 ```
 loki     (wave 2) → Helm chart
 promtail (wave 2) → Helm chart
 grafana  (wave 2) → Helm chart
 ```
 **Option A:** Create "logging-stack" with all three  
 **Option B:** Keep separate (grafana used by multiple systems)
 **Recommendation:** Keep separate for now (grafana has multiple consumers)
 ---
 ## Implementation Order
 ### Sprint 1: Phase 1 (Low Risk)
 1. ✅ ingress-config (wildcard-cert + homelab-ingress)
 2. ✅ homarr (merge homarr-patches)
 3. ✅ temporal (merge db-secret-sync)
 4. ✅ cert-manager (merge issuers)
 ### Sprint 2: Phase 2 (Moderate Risk)
 5. ✅ Remove duplicate ingress-nginx
 6. ✅ sqs-platform consolidation
 7. ✅ authentik + iam-jobs
 ### Sprint 3: Phase 3 (Optional)
 8. ⚠️ Evaluate monitoring stack consolidation
 9. ⚠️ Evaluate logging stack consolidation
 ---
 ## File Changes Required
 ### For each consolidation:
 1. **Update Application YAML** in `k8s/argocd/apps/*.yaml`
   - Convert single-source to multi-source
   - Update sync waves appropriately
   - Add hook annotations where needed
 2. **Update kustomization.yaml** in target directories
   - Ensure all resources are listed
   - Verify namespace declarations
 3. **Test locally:**
   ```bash
   kubectl kustomize k8s/bootstrap/ingress/
   helm template <chart> -f values.yaml
   ```
 4. **Delete old Applications:**
   ```bash
   kubectl delete application <old-app> -n argocd
   ```
 ---
 ## Rollback Plan
 Each consolidation is independent. If issues arise:
 1. **Revert git commit** with the Application change
 2. **Restore old Applications** from git history
 3. **Force ArgoCD refresh:**
   ```bash
   kubectl delete application <new-merged-app> -n argocd
   kubectl apply -f k8s/argocd/apps/<old-wave-file>.yaml
   ```
 ---
 ## Success Metrics
 **Before:** 39 Applications  
 **After (Conservative):** 35 Applications  
 **After (Full):** 31-32 Applications
 **Benefits:**
 - ✅ Easier to understand (related apps grouped)
 - ✅ Fewer Application CRs to manage
 - ✅ Cleaner ArgoCD UI
 - ✅ Logical grouping by function
 - ✅ Reduced sync complexity
 **Risks:**
 - ⚠️ Multi-source Applications are slightly more complex
 - ⚠️ Sync wave ordering must be preserved
 - ⚠️ Hook timing must be correct (PreSync/PostSync)
 ---
 ## Decision: Which Phase?
 **Recommendation:** Start with **Phase 1 (Conservative)** → 35 Applications
 This gives us:
 - 4 fewer Applications to manage
 - Low risk (same directories)
 - Easy to understand merges
 - Can evaluate Phase 2 later based on results
 **Do you want to proceed with Phase 1 implementation?**

 # ArgoCD Application Consolidation - Implementation Results
 ## Summary
 **Before:** 39 Applications  
 **After:** 35 Applications  
 **Removed:** 4 Applications (-10.3%)
 ## Implemented Merges
 ### ✅ 1. ingress-config ← wildcard-cert + homelab-ingress
 **Before:**
 - `wildcard-cert` (wave 1): k8s/bootstrap/ingress/riotpiao-com-cert.yaml
 - `homelab-ingress` (wave 2): k8s/bootstrap/ingress/ingress.yaml
 **After:**
 - `ingress-config` (wave 1): k8s/bootstrap/ingress/ (kustomization)
 **Changes:**
 - Updated `k8s/bootstrap/ingress/kustomization.yaml` to include both files
 - Merged both Applications into single `ingress-config` in `00-substrate.yaml`
 - Certificate created before Ingresses (wave 1)
 ---
 ### ✅ 2. homarr ← homarr + homarr-patches
 **Before:**
 - `homarr` (wave 8): Helm chart + values
 - `homarr-patches` (wave 9): k8s/applications/homarr/ (PostSync hook)
 **After:**
 - `homarr` (wave 8): Multi-source (Helm + values + PostSync patches)
 **Changes:**
 - Added third source to homarr Application
 - fix-probes-job.yaml already has PostSync hook annotation
 - Removed homarr-patches Application from `60-applications.yaml`
 ---
 ### ✅ 3. temporal ← temporal + temporal-db-secret-sync
 **Before:**
 - `temporal-db-secret-sync` (wave 7): k8s/applications/temporal/db-secret-sync/
 - `temporal` (wave 8): Helm chart + values
 **After:**
 - `temporal` (wave 8): Multi-source (Helm + values + PostSync db-secret-sync)
 **Changes:**
 - Added third source to temporal Application
 - copy-job.yaml already has PostSync hook annotation
 - Removed temporal-db-secret-sync Application from `60-applications.yaml`
 ---
 ### ✅ 4. Removed Duplicate: ingress-nginx
 **Before:**
 - `ingress-nginx-bootstrap` (bootstrap): Working, has LoadBalancer IP
 - `ingress-nginx` (ArgoCD): Duplicate, LoadBalancer pending
 **After:**
 - `ingress-nginx-bootstrap` (bootstrap): Kept
 **Changes:**
 - Removed ingress-nginx Application from `00-substrate.yaml`
 - Bootstrap version breaks circular dependency (ArgoCD → Forgejo → Ingress)
 - Eliminated duplicate DaemonSet
 ---
 ## Skipped Consolidations
 ### ⏭️ cert-manager + cert-manager-issuers
 **Decision:** KEEP SEPARATE
 **Reasoning:**
 - cert-manager (wave 0) installs CRDs
 - cert-manager-issuers (wave 1) creates Issuers using those CRDs
 - Wave separation ensures CRDs exist before Issuers
 - Merging risks race condition (Issuer created before CRD ready)
 - This is intentional separation for safety
 ---
 ## Files Modified
 1. `k8s/bootstrap/ingress/kustomization.yaml` - Added resources list
 2. `k8s/argocd/apps/00-substrate.yaml` - Merged wildcard-cert + homelab-ingress, removed ingress-nginx
 3. `k8s/argocd/apps/60-applications.yaml` - Merged homarr + temporal Applications
 ---
 ## Benefits Achieved
 ### ✅ Easier Management
 - 4 fewer Application CRs to track
 - Related resources grouped together
 - Clearer ownership model
 ### ✅ Better Sync Behavior
 - PostSync hooks ensure proper ordering
 - No separate Applications for patches/hooks
 - Single Application manages entire stack
 ### ✅ Cleaner Structure
 - Multi-source Applications are standard pattern
 - Each logical service = one Application
 - Hooks embedded where they belong
 ---
 ## Next Steps (Optional Phase 2)
 ### Potential Future Consolidations:
 1. **SQS Platform** (5 → 2 Applications)
   - Keep `strimzi-operator` separate
   - Merge: kmsvc-redis + kafka-cluster + queue-crd + management-service
 2. **IAM** (3 → 2 Applications)
   - Keep `vault` separate
   - Merge: authentik + iam-jobs
 3. **Monitoring** (3 → 2 Applications)
   - Keep `prometheus-crds` separate (wave 0)
   - Merge: prometheus + blackbox-exporter
 **Recommendation:** Evaluate after Forgejo push and observe current consolidations in action.
 ---
 ## Validation Plan
 After pushing to Forgejo:
 ```bash
 # Check Applications synced successfully
 kubectl get applications -n argocd
 # Verify consolidated Applications are healthy
 kubectl get application ingress-config -n argocd
 kubectl get application homarr -n argocd
 kubectl get application temporal -n argocd
 # Check ingress-nginx duplicate removed
 kubectl get application ingress-nginx -n argocd  # Should be gone
 # Verify resources deployed correctly
 kubectl get certificate -n ingress-nginx riotpiao-com-tls
 kubectl get ingress -A
 kubectl get job -n dashboard homarr-fix-probes
 kubectl get job -n temporal temporal-db-secret-sync
 ```
 ---
 ## Rollback Procedure
 If issues arise, revert specific commits:
 ```bash
 # Identify commit
 git log --oneline | grep consolidation
 # Revert specific merge
 git revert <commit-hash>
 # Or restore old Applications from git history
 git show <commit>:k8s/argocd/apps/00-substrate.yaml > temp.yaml
 kubectl apply -f temp.yaml
 ```
 ---
 ## Conclusion
 Successfully consolidated 4 Applications while maintaining:
 - ✅ Proper sync wave ordering
 - ✅ Hook execution timing
 - ✅ Resource namespace separation
 - ✅ GitOps best practices
 **Status:** Ready to commit and push to Forgejo for validation.
