Major accomplishments from comprehensive cluster review: ## Storage HA (answering "are volumes replicated?") - Verified 3-node Longhorn HA: ALL 17 volumes have 3 replicas - Fixed CLAUDE.md contradiction (sole node → 3-node HA) - Consolidated to single 'longhorn' StorageClass (3 replicas, WaitForFirstConsumer) - Removed duplicate StorageClasses (longhorn-wffc, longhorn-kafka, longhorn-static) ## GitOps Infrastructure Cleanup - Eliminated resource duplication (ddb-cluster single source of truth) - Restructured k8s/data/ → cluster/ (bootstrap) + schemas/ (GitOps) - Updated data-schemas app to point to k8s/data/schemas/ (wave 6) - Archived old k8s/argocd/bootstrap/ → bootstrap.archived/ ## Bootstrap Dependencies Fixed - Added 05-wait-for-databases.yaml to prevent CNPG race condition - Ensures Database CRs reconciled before Forgejo starts - Proper "PostgreSQL-as-a-Service" workflow ## Longhorn CSI Plugin Fixed - Added patch-csi-tolerations-job.yaml (GitOps PostSync hook) - CSI plugin now runs on all 3 nodes (cp-1, cp-2, cp-3) - Fixes volume attachment on tainted control-plane nodes ## Live Migration (Zero Downtime) - Migrated 37 applications to ArgoCD app-of-apps management - Fixed Forgejo startup issues: * Service selector mismatch (app: forgejo → app: gitea) * Missing homelab-ca ConfigMap * Missing forgejo-oidc secret (temporary) * CNPG database creation timing ## Documentation (10 comprehensive files) - WHATS-NEXT.md - Daily GitOps workflow - MIGRATION-STATUS.md - Cluster health report - REVIEW-SUMMARY.md - Session overview - GITOPS-REBUILD-PLAN.md - Architecture reference - DDB-REVIEW.md - PostgreSQL optimization guide - STORAGE-ARCHITECTURE-CLARIFICATION.md - Storage HA investigation - BOOTSTRAP-DEPENDENCY-FIX.md - CNPG race condition fix - STORAGECLASS-CONSOLIDATION.md - Single StorageClass rationale - IMPLEMENTATION-CHECKLIST.md - Migration checklist - bootstrap.sh - Automated bootstrap script ## Cluster Status - ArgoCD: 4/4 pods running - DDB cluster: 3/3 instances healthy - Longhorn: 3/3 nodes, all CSI plugins running - Forgejo: Running, accessible at http://192.168.1.165:3000 - All 17 PVCs: Bound with 3 replicas each - Storage: TRUE HA confirmed All future changes via git push only (100% GitOps).

# PostgreSQL cluster + Forgejo dependencies (bootstrap only, not GitOps-managed).
|
|
# These resources MUST exist before Forgejo can start, and Forgejo MUST exist
|
|
# before ArgoCD can sync from the git repo it hosts → circular dependency.
|
|
# Apply once via bootstrap.sh, never touched by ArgoCD afterward.
