From dafccd5d72ab4b3393b6cb90c94534baaa03140c Mon Sep 17 00:00:00 2001 From: Story Crater Bot <19826264+Riotpiaole@users.noreply.github.com> Date: Wed, 22 Jul 2026 23:56:34 -0700 Subject: [PATCH] feat: complete GitOps migration, storage HA verification, and cluster fixes MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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 โ†’ 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/ โ†’ cluster/ (bootstrap) + schemas/ (GitOps) - Updated data-schemas app to point to k8s/data/schemas/ (wave 6) - Archived old k8s/argocd/bootstrap/ โ†’ 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 โ†’ 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). --- BOOTSTRAP-DEPENDENCY-FIX.md | 227 +++++++++ DDB-REVIEW.md | 228 +++++++++ GITOPS-REBUILD-PLAN.md | 459 +++++++++++++++++ IMPLEMENTATION-CHECKLIST.md | 405 +++++++++++++++ MIGRATION-STATUS.md | 201 ++++++++ REVIEW-SUMMARY.md | 475 ++++++++++++++++++ STORAGE-ARCHITECTURE-CLARIFICATION.md | 304 +++++++++++ STORAGE-MIGRATION-ANALYSIS.md | 121 +++++ STORAGECLASS-CONSOLIDATION.md | 194 +++++++ WHATS-NEXT.md | 329 ++++++++++++ bootstrap.sh | 130 +++++ fix-forgejo.sh | 77 +++ k8s/argocd/apps/40-data.yaml | 11 +- .../BOOTSTRAP.md | 0 .../cnpg-operator.yaml | 0 .../forgejo.yaml | 0 .../sops-cmp-generate.sh | 0 k8s/bootstrap-local/00-namespaces.yaml | 115 +++++ k8s/bootstrap-local/01-argocd.yaml | 47 ++ k8s/bootstrap-local/02-cnpg-operator.yaml | 30 ++ k8s/bootstrap-local/03-ddb-bootstrap.yaml | 152 ++++++ k8s/bootstrap-local/04-forgejo.yaml | 151 ++++++ .../05-wait-for-databases.yaml | 89 ++++ k8s/bootstrap-local/kustomization.yaml | 23 + k8s/data/{ => cluster}/ddb-cluster.yaml | 7 +- k8s/data/{ => cluster}/forgejo-database.yaml | 0 k8s/data/cluster/kustomization.yaml | 17 + k8s/data/kustomization.yaml | 21 -

The `04-forgejo.yaml` Application already exists, just change `syncPolicy.automated` to enable it. + +**Q: What if bootstrap.sh fails halfway?** +A: Re-run it. All commands are idempotent (`kubectl apply`, `--dry-run=client -o yaml | kubectl apply`). + +**Q: How do I rollback a bad GitOps change?** +A: `git revert ` โ†’ `git push`. ArgoCD auto-syncs the rollback. + +**Q: Why rename wave numbers (00 โ†’ 0, 05 โ†’ 1, etc.)?** +A: Cleaner sequential naming (0-8). Old helmfile convention used gaps (00, 05, 10, ...) which are unnecessary in pure ArgoCD. + +**Q: Can I delete k8s/argocd/bootstrap/ after migration?** +A: Yes, once bootstrap-local/ is working.
