This was a security-focused breaking change. - -**Impact on n8n**: -1. n8n connects to database successfully ✓ -2. n8n attempts to create `migrations` table during first run -3. PostgreSQL returns: `QueryFailedError: permission denied for schema public` -4. n8n exits with status code 1 -5. Systemd auto-restarts service → crash loop begins - -**Evidence from Logs**: -``` -QueryFailedError: permission denied for schema public - at PostgresQueryRunner.query - at MigrationExecutor.executePendingMigrations -Error occurred during database migration: permission denied for schema public -``` - -**Why This Wasn't Caught Earlier**: -- Documentation and tutorials written for PostgreSQL < 15 still work with old defaults -- Debian 12 ships with PostgreSQL 16, inheriting the PG15+ security model -- The breaking change is not well-documented in n8n deployment guides - -### Root Cause #2: Locale Name Syntax Mismatch - -**The Discovery**: -During script deployment attempts, PostgreSQL consistently rejected database creation with locale errors: - -1. **First attempt**: `en_US.UTF-8` → Not available (minimal Debian 12 LXC container) -2. **Second attempt**: `C.UTF-8` → Invalid locale name error -3. **System verification**: `locale -a` showed only: C, **C.utf8** (lowercase), POSIX -4. **Final solution**: Use `C.utf8` (lowercase 'utf8') - -**Why This Matters**: -- PostgreSQL locale names must **exactly match** system-available locales -- Different distributions use different locale naming conventions -- Debian 12 minimal: Uses `C.utf8` (lowercase) -- Ubuntu/full Debian: Often includes `en_US.UTF-8` and `C.UTF-8` -- This is NOT a PostgreSQL bug - it's correctly validating against system locales - -**Error Message**: -``` -ERROR: invalid locale name: "C.UTF-8" -``` - -### The Complete Fix: fix_n8n_db_c_locale.sh - -**Script Location**: `/home/jramos/homelab/scripts/fix_n8n_db_c_locale.sh` - -**What It Does**: -1. **Backup Operations**: - - Creates timestamped PostgreSQL dump (if n8n_db exists) - - Stores in `/var/backups/n8n/` - -2. **Database Recreation with Correct Locale**: - - Terminates active connections - - Drops existing n8n_db (if exists) - - Creates new database with: - - `OWNER = n8n_user` - - `ENCODING = 'UTF8'` - - `LC_COLLATE = 'C.utf8'` (lowercase - matches system) - - `LC_CTYPE = 'C.utf8'` (lowercase - matches system) - -3. **PostgreSQL 15+ Permission Grants**: - - `GRANT ALL PRIVILEGES ON DATABASE n8n_db TO n8n_user;` - - `GRANT ALL ON SCHEMA public TO n8n_user;` - - `GRANT CREATE ON SCHEMA public TO n8n_user;` ← **Critical for PG15+** - -4. **Service Restart**: - - Restarts n8n service - - Allows migrations to run successfully - -**Key Corrections from Previous Scripts**: -- ❌ `en_US.UTF-8` → ✅ `C.utf8` (matches `locale -a` output) -- ❌ `C.UTF-8` (uppercase) → ✅ `C.utf8` (lowercase) -- ✅ Retains all PostgreSQL 15+ permission grants - -### System State Verification - -**PostgreSQL Version**: 16.11 (Debian 16.11-1.pgdg120+1) - -**Available Locales**: Minimal set (verified via `locale -a`) -``` -C -C.utf8 ← This is the one we need -POSIX -``` - -**Database User Status**: -```bash -postgres=# \du n8n_user - List of roles - Role name | Attributes | Member of ------------+------------+----------- - n8n_user | | {} -``` -- User exists ✓ -- Currently has no special privileges (SUPERUSER, CREATEDB, etc.) -- Will gain necessary permissions through GRANT statements in fix script - -**Database Status**: -```bash -postgres=# \l n8n_db -ERROR: database "n8n_db" does not exist -``` -- Database does NOT currently exist -- Previous creation attempts failed due to locale errors -- Fix script will create it with correct locale - -### Deployment Checklist - -**Pre-Deployment**: -- [x] Verify PostgreSQL service running on CT 113 -- [x] Verify n8n_user exists in PostgreSQL -- [x] Verify available locales (`locale -a`) -- [x] Script validated by Backend-Builder and Lab-Operator -- [x] Script corrected for C.utf8 locale -- [ ] Create ZFS snapshot: `pct snapshot 113 pre-n8n-final-fix` -- [ ] Transfer script to CT 113 - -**Deployment Steps**: -- [ ] Copy script: `scp /home/jramos/homelab/scripts/fix_n8n_db_c_locale.sh root@192.168.2.113:/tmp/` -- [ ] SSH to CT 113: `ssh root@192.168.2.113` -- [ ] Execute script: `bash /tmp/fix_n8n_db_c_locale.sh` -- [ ] Monitor output for errors -- [ ] Verify n8n service status: `systemctl status n8n` -- [ ] Check service logs: `journalctl -u n8n -f` (should show successful migration) -- [ ] Test local access: `curl http://localhost:5678` -- [ ] Delete script: `shred -u /tmp/fix_n8n_db_c_locale.sh` (contains password) - -**Post-Deployment Verification**: -- [ ] External access test: `https://n8n.apophisnetworking.net` (from mobile/external) -- [ ] Internal access test: `http://192.168.2.113:5678` (from lab network) -- [ ] NPM logs check: Verify successful proxying (no 502 errors) -- [ ] Monitor service stability: Check every 5 minutes for 1 hour -- [ ] Database verification: Connect to n8n_db and verify tables exist -- [ ] n8n UI test: Complete initial setup wizard -- [ ] Create test workflow and verify execution - -**24-Hour Monitoring**: -- [ ] Check service status at 1 hour post-deployment -- [ ] Check service status at 6 hours post-deployment -- [ ] Check service status at 24 hours post-deployment -- [ ] Review logs for any warnings or errors -- [ ] Document final working configuration - -**Rollback Procedure** (if needed): -1. Stop n8n service: `systemctl stop n8n` -2. Restore ZFS snapshot: `pct rollback 113 pre-n8n-final-fix` -3. Or restore database from backup: `psql n8n_db < /var/backups/n8n/n8n_db_backup_*.sql` -4. Review logs to identify new issues -5. Contact agent team for further analysis - -### Expected Outcome - -**Before Fix**: -``` -n8n starts → attempts CREATE TABLE migrations → PERMISSION DENIED → exit code 1 → restart → loop -``` - -**After Fix**: -``` -n8n starts → CREATE TABLE migrations → SUCCESS → run migrations → tables created → SERVICE RUNNING ✓ -``` - -**Success Indicators**: -1. `systemctl status n8n` shows: `Active: active (running)` (stable, no restarts) -2. Process stays running (no PID changes over 5+ minutes) -3. `journalctl -u n8n` shows: "Editor is now accessible via: http://localhost:5678/" -4. Database contains migration tables: `\dt` in psql shows multiple n8n tables -5. External access works: `https://n8n.apophisnetworking.net` loads n8n UI -6. NPM logs show successful proxying: HTTP 200 responses instead of 502 - -### Lessons Learned - -**PostgreSQL Version Compatibility**: -- Always check PostgreSQL version when deploying applications -- PostgreSQL 15+ requires explicit schema permission grants -- Breaking changes in major versions can affect application deployments -- Test deployment scripts on target PostgreSQL version - -**Locale Configuration**: -- Never assume locale availability across different distributions -- Minimal LXC containers have limited locale sets -- Always verify with `locale -a` before hardcoding locale names -- PostgreSQL locale names must **exactly match** system locales (case-sensitive) -- `C.utf8` ≠ `C.UTF-8` (even though both represent similar concepts) - -**Troubleshooting Methodology**: -- Service crash loops require log analysis, not just status checks -- PostgreSQL error messages are precise - read them carefully -- Test each fix independently to identify which issue is blocking -- Document system state (versions, available resources) before troubleshooting - -**Documentation Quality**: -- Many online guides are outdated for PostgreSQL 15+ -- Official PostgreSQL release notes document breaking changes -- n8n documentation doesn't explicitly address PG15+ permission changes -- Homelab documentation should include exact versions for reproducibility - -**NPM Reverse Proxy Configuration**: -- NPM "scheme" setting defines backend communication protocol (not external) -- Correct setup: `http` scheme to backend + Force SSL enabled for external clients -- SSL termination happens at NPM (not at application backend) -- Using `https` scheme when backend listens on HTTP causes 502 errors -- This is standard reverse proxy SSL termination architecture -

-### Post-Migration Tasks - -**Immediate Actions Required** (before deployment): -- [ ] Review and update secrets in docker-compose files -- [ ] Create/update `.env` files with production credentials -- [ ] Verify host volume mount paths exist: - - `/home/jramos/docker/bytestash/data` - - `/home/docker/filebrowser/` - - `/home/jramos/paperless-ngx/consume` - - `/home/jramos/docker/speedtest-tracker/config` -- [ ] Ensure `portainer_data` Docker volume exists - -**Recommended Next Steps**: -- [ ] Commit staged changes to git -- [ ] Push to Gitea repository -- [ ] Test service deployments one by one -- [ ] Configure NPM proxy hosts for external access -- [ ] Document any deployment-specific customizations -- [ ] Plan GitLab VM 101 decommissioning timeline - -### Lessons Learned - -**GitLab Access Resolution**: -- Initial clone attempts failed at 192.168.2.101 (NPM, not GitLab) -- GitLab VM 101 was powered off according to Proxmox status -- Actual GitLab accessible at domain: https://vulcan.apophisnetworking.net -- oauth2 PAT format required for git clone authentication -

-#### 1. Template Files Created - -**services/homepage/services.yaml.template**: -- Created template with environment variable placeholders -- Replaced 7 sensitive credentials with `${VARIABLE_NAME}` format: - - `${OPNSENSE_API_USERNAME}` and `${OPNSENSE_API_PASSWORD}` - - `${PROXMOX_HOMERAMOSLAB_API_TOKEN}` and `${PROXMOX_PVE_API_TOKEN}` - - `${PLEX_API_KEY}` - - `${RADARR_API_KEY}` and `${SONARR_API_KEY}` - - `${DELUGE_WEBUI_PASSWORD}` -- Added header comments explaining template usage -- File location: `/home/jramos/homelab/services/homepage/services.yaml.template` - -**scripts/fix_n8n_db_c_locale.sh.template**: -- Created template requiring `N8N_DB_PASSWORD` environment variable -- Removed hardcoded database password (`Nbkx4mdmay1)`) -- Added validation to ensure environment variable is set before execution -- Added security reminder to delete script after use (`shred -u`) -- File location: `/home/jramos/homelab/scripts/fix_n8n_db_c_locale.sh.template` - -#### 2. .gitignore Updates - -Added specific exclusions to prevent committing sensitive files: - -```gitignore -# Homepage Configuration (Sensitive) -services/homepage/services.yaml - -# Operational Scripts (Sensitive) -scripts/fix_n8n_db_c_locale.sh -``` - -**Note**: Generic patterns were already in place (e.g., `services/**/.env`, `scripts/**/*_with_creds.*`), but explicit exclusions were added for clarity and fail-safe protection. - -#### 3. Documentation Created - -**services/homepage/README.md** (new file): -- Comprehensive 250+ line setup guide -- Two setup methods: environment variables (recommended) vs manual configuration -- Step-by-step instructions for obtaining API keys from each service -- Docker Compose integration examples -- Troubleshooting section for common issues -- Security best practices (permissions, token rotation, HTTPS) -- Template maintenance guidelines - -**scripts/README.md** (updated): -- Added new section documenting `fix_n8n_db_c_locale.sh` template -- Created "Template-Based Script Pattern" section explaining the workflow -- Enhanced "Security Notes" with general guidelines -- Updated directory structure to show template files -- Added comparison with legacy scripts - -### Template-Based Security Pattern - -This implementation establishes a **standard pattern** for managing sensitive data in the repository: - -**Pattern Components**: -1. **Template files** (`.template` extension): Tracked in git, contain `${VARIABLE_NAME}` placeholders -2. **Active files**: Excluded from git, contain actual credentials -3. **Documentation**: README files explain how to use templates -4. **.gitignore**: Explicitly excludes active files - -**Workflow**: -```bash -# 1. Copy template to create working file -cp file.template file - -# 2. Set credentials via environment variable or edit file -export VARIABLE_NAME='actual_value' - -# 3. Use the file -[run script or start service] - -# 4. Securely delete if temporary (scripts) -shred -u file # For scripts with embedded credentials -``` - -**Benefits**: -- Repository remains credential-free -- Templates serve as documentation -- Easy to recreate configurations on new systems -- Version control tracks logic without exposing secrets -- Supports CI/CD pipelines (inject credentials from secrets management) - -### Files Changed - -**New Files**: -- `/home/jramos/homelab/services/homepage/services.yaml.template` (87 lines) -- `/home/jramos/homelab/services/homepage/README.md` (260 lines) -- `/home/jramos/homelab/scripts/fix_n8n_db_c_locale.sh.template` (163 lines) - -**Modified Files**: -- `/home/jramos/homelab/.gitignore` (added 10 lines for explicit exclusions) -- `/home/jramos/homelab/scripts/README.md` (added 70+ lines documenting template pattern) -- `/home/jramos/homelab/CLAUDE_STATUS.md` (this section) -

-**Post-Implementation**: -- [x] Sensitive files excluded from git tracking -- [x] Templates provide clear migration path -- [x] Pattern documented for future use -- [x] READMEs guide users through secure setup - -### Lessons Learned - -**Credential Management**: -- Always use environment variables for sensitive data in scripts -- Template files are superior to example files (they contain actual structure) -- Explicit .gitignore entries are safer than relying on wildcards alone - -**Documentation Quality**: -- Include API key acquisition instructions (reduces friction) -- Provide both manual and automated workflows -- Explain WHY security measures exist, not just HOW - -**Repository Hygiene**: -- Proactive security reviews prevent credential leaks -- Template pattern scales well to multiple services -- Clear documentation reduces security incidents - -### Next Steps - -**Immediate**: -- [x] Stage all template files and documentation -- [x] Verify .gitignore excludes sensitive files -- [ ] Create commit with security-focused message -- [ ] Push to Gitea repository - -**Future Enhancements**: -- Consider using `.env.example` files for services requiring multiple variables -- Evaluate secret management tools (Vault, SOPS) for production deployments -- Create automated validation scripts to detect credentials in commits (pre-commit hook) +### Recommended Manual Tasks +- **Weekly**: Review Grafana dashboards for anomalies +- **Monthly**: Update monitoring stack Docker images +- **Quarterly**: Review backup retention policies +- **Semi-Annual**: Kernel updates on Proxmox host and VMs --- -## Current Task: Repository Reorganization and Commit +## Known Issues & Resolutions -**Started**: 2025-12-02 -**Completed**: 2025-12-02 21:45 MST -**Goal**: Review repository reorganization changes and commit to local repo, then push to Gitea -**Phase**: ✅ COMPLETED -**Status**: Successfully committed and pushed to Gitea +### Resolved +-  n8n PostgreSQL locale errors (fixed with `fix_n8n_db_c_locale.sh`) +-  n8n database permissions (fixed with `fix_n8n_db_permissions.sh`) -### Task Breakdown +### Active Monitoring +- PVE Exporter SSL verification (set to false for self-signed certificates) +- Prometheus retention policies (currently 15 days, may need adjustment) -- [x] **Step 1**: Librarian reviews all staged and untracked changes -
