⚠️ Issues Found

🔴 Critical Issues: 0

🟡 High Priority Issues: 1

1. Nginx Proxy Manager Not Removed/Migrated

• File: compose/core/nginxproxymanager/compose.yml
• Issue: Template file still exists with .yml extension and no configuration
• Impact: Will fail CI validation workflow
• Recommendation:

  # Option 1: Remove if not needed (Traefik replaces it)
  rm -rf compose/core/nginxproxymanager/
  
  # Option 2: Configure if needed alongside Traefik
  # Move to compose.yaml and configure properly
  

🟠 Medium Priority Issues: 3

2. Missing Password Synchronization Documentation

• Files: compose/core/lldap/.env, compose/core/tinyauth/.env
• Issue: Password must match between LLDAP and Tinyauth, not clearly documented
• Recommendation: Add a note in both .env files:

  # IMPORTANT: This password must match LLDAP_LDAP_USER_PASS in ../lldap/.env
  LDAP_BIND_PASSWORD=changeme_please_set_secure_password
  

3. Vikunja Database Password Duplication

• File: compose/services/vikunja/compose.yaml
• Issue: Database password defined in two places (can get out of sync)
• Recommendation: Use .env file for Vikunja service

  env_file: .env
  environment:
    VIKUNJA_DATABASE_PASSWORD: ${POSTGRES_PASSWORD}
  

4. Immich External Photo Library Mounting

• File: compose/media/frontend/immich/compose.yaml
• Issue: Added /media/photos mount, but Immich uses UPLOAD_LOCATION for primary storage
• Recommendation: Document that /media/photos is for external library import only

🔵 Low Priority / Nice-to-Have: 5

5. Inconsistent Timezone

• Files: Various compose files
• Issue: Some services use America/Los_Angeles, others don't specify
• Recommendation: Standardize timezone across all services or use .env

6. Booklore Image May Not Exist

• File: compose/services/booklore/compose.yaml
• Issue: Using ghcr.io/lorebooks/booklore:latest - verify this image exists
• Recommendation: Test image availability before deployment

7. Port Conflicts Possible

• Issue: Several services expose ports that may conflict
  • Traefik: 80, 443
  • Jellyfin: 8096, 7359
  • Immich: 2283
  • qBittorrent: 6881
• Recommendation: Document port requirements in README

8. Missing Resource Limits

• Issue: No CPU/memory limits defined
• Impact: Services could consume excessive resources
• Recommendation: Add resource limits in production:

  deploy:
    resources:
      limits:
        cpus: '1.0'
        memory: 1G
  

9. GitHub Actions May Need Secrets

• File: .github/workflows/security-checks.yml
• Issue: Some workflows assume GITHUB_TOKEN is available
• Recommendation: Document required GitHub secrets in README

🔍 Detailed Review by Category

Core Infrastructure

Traefik (compose/core/traefik/compose.yaml)

✅ Excellent

• Proper entrypoint configuration
• HTTP to HTTPS redirect
• Let's Encrypt email configured
• Dashboard with SSO protection
• Log level appropriate for production

Suggestion: Consider adding access log retention:

- --accesslog.filepath=/var/log/traefik/access.log
- --accesslog.bufferingsize=100

LLDAP (compose/core/lldap/compose.yaml)

✅ Good

• Clean configuration
• Proper volume mounts
• Environment variables in .env

Minor Issue: Base DN is dc=fig,dc=systems but domain is fig.systems - this is correct but document why.

Tinyauth (compose/core/tinyauth/compose.yaml)

✅ Good

• LDAP integration properly configured
• Forward auth middleware defined
• Session management configured

Issue: Depends on LLDAP - add depends_on if deploying together.

Media Services

Jellyfin ✅ Excellent

• Proper media folder mappings
• GPU transcoding option documented
• Traefik labels complete
• SSO middleware commented (correct for service with own auth)

Sonarr/Radarr ✅ Good

• Download folder mappings correct
• Consistent configuration
• Proper network isolation

Suggestion: Add Traefik rate limiting for public endpoints:

traefik.http.middlewares.sonarr-ratelimit.ratelimit.average: 10

Immich ⭐ Very Good

• Multi-container setup properly configured
• Internal network for database/redis
• Health checks present
• Machine learning container included

Question: Does /media/photos need write access? Currently read-only.

Utility Services

Linkwarden/Vikunja ✅ Excellent

• Multi-service stacks well organized
• Database health checks
• Internal networks isolated

File Browser ⚠️ Needs Review

• Mounts entire /media to /srv
• This gives access to ALL media folders
• Consider if this is intentional or security risk

CI/CD Pipeline

GitHub Actions Workflows ⭐⭐⭐⭐⭐ Outstanding

• Comprehensive validation
• Security scanning with multiple tools
• Documentation verification
• Auto-labeling

One Issue: docker-compose-validation.yml line 30 assumes homelab network exists for validation. This will fail on CI runners.

Fix:

# Skip network existence validation, only check syntax
if docker compose -f "$file" config --quiet 2>/dev/null; then

---

🧪 Testing Performed

Based on the implementation, these tests should be performed:

✅ Automated Tests (Will Run via CI)

• YAML syntax validation
• Compose file structure
• Secret scanning
• Documentation links

⏳ Manual Tests Required

• Deploy Traefik and verify dashboard
• Deploy LLDAP and create test user
• Configure Tinyauth with LLDAP
• Deploy a test service and verify SSO
• Verify SSL certificate generation
• Test dual domain access (fig.systems + edfig.dev)
• Verify media folder permissions (PUID/PGID)
• Test service interdependencies
• Verify health checks work
• Test backup/restore procedures

---

📝 Recommendations

Before Merge:

1. Fix nginxproxymanager issue - Remove or migrate to compose.yaml

💬 Questions for PR Author

1. Nginx Proxy Manager: Is this service still needed or can it be removed since Traefik is the reverse proxy?

2. Media Folder Permissions: Have you verified the host will have PUID=1000, PGID=1000 for the media folders?

3. Backup Strategy: What's the plan for backing up:

   • LLDAP user database
   • Service configurations
   • Application databases (Postgres)

4. Monitoring: Plans for adding monitoring/alerting (Grafana, Uptime Kuma, etc.)?

5. Testing: Have you tested the full deployment flow on a clean system?
