## ⚠️ 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:**
|
||||
```bash
|
||||
# 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:
|
||||
```bash
|
||||
# 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
|
||||
```yaml
|
||||
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:
|
||||
```yaml
|
||||
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:
|
||||
```yaml
|
||||
- --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:
|
||||
```yaml
|
||||
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:**
|
||||
```yaml
|
||||
# Skip network existence validation, only check syntax
|
||||
if docker compose -f "$file" config --quiet 2>/dev/null; then
|
||||
```
|
||||

||||
