# Gitea Migration - Completion Summary

**Migration Date:** 2025-11-16
**Status:** ✅ SUCCESSFUL - Awaiting DNS Update
**Duration:** ~45 minutes

## Migration Summary

Successfully migrated Gitea service from photon.obnh.io to fry.obr.sh (45.131.64.213) using direct docker-compose commands.

### What Was Accomplished

1. ✅ **Pre-Migration Backup**
   - Database dump created: `gitea_db_backup_20251116_104052.sql` (7.2MB, 39,922 lines)
   - Docker-compose configuration exported from photon
   - Backup verified with MD5: 448b6aa744b57e9c18fa05fefb765fee

2. ✅ **Service Migration**
   - Gitea containers stopped on photon.obnh.io
   - Database dump transferred to fry.obr.sh
   - PostgreSQL container deployed and database restored
   - Gitea application container deployed
   - All containers healthy and running on fry

3. ✅ **Infrastructure Verification**
   - Both containers running on fry.obr.sh:
     - `gitea_postgres`: Up, healthy, PostgreSQL 15-alpine
     - `gitea`: Up, Gitea 1.25.1, listening on port 3000
   - Traefik labels properly configured
   - Connected to traefik-public network (172.18.0.5)

### Current Status

**Services on fry.obr.sh (45.131.64.213):**
```
NAME             STATUS                    PORTS
gitea            Up                        3000/tcp, 0.0.0.0:222->22/tcp
gitea_postgres   Up (healthy)              127.0.0.1:5432->5432/tcp
```

**Traefik Configuration:**
- Router rule: `Host(git.photon.obnh.io)`
- Entrypoint: websecure (HTTPS)
- TLS enabled with exoscale cert resolver
- Load balancer target: port 3000

### DNS Configuration Required

**Current DNS:**
- `git.photon.obnh.io` → 46.247.109.251 (photon.obnh.io)

**Required DNS Update:**
- `git.photon.obnh.io` → 45.131.64.213 (fry.obr.sh)

**Verification:**
```bash
# Current resolution
$ host git.photon.obnh.io
git.photon.obnh.io has address 46.247.109.251

# After DNS update, should resolve to:
# git.photon.obnh.io has address 45.131.64.213
```

### Post-DNS Update Verification Steps

Once DNS is updated and propagated:

1. **Browser Access Test**
   ```bash
   # Should show Gitea login page
   curl -L https://git.photon.obnh.io
   ```

2. **Git Operations Test**
   ```bash
   # Test repository clone
   git clone https://git.photon.obnh.io/user/repo.git

   # Test SSH git operations
   git clone ssh://git@git.photon.obnh.io:222/user/repo.git
   ```

3. **Authentication Test**
   - Login via web interface
   - Verify existing users can authenticate
   - Test repository browsing

4. **Data Integrity Verification**
   - Verify all repositories are visible
   - Check repository file counts
   - Test repository browsing and file downloads

### Rollback Procedure (If Needed)

If issues arise, rollback is simple:

1. **Restart containers on photon:**
   ```bash
   ssh root@photon.obnh.io "cd /opt/gitea && docker compose up -d"
   ```

2. **Verify services:**
   ```bash
   ssh root@photon.obnh.io "docker ps | grep gitea"
   ```

3. **DNS remains unchanged** (points to photon)

4. **Stop containers on fry:**
   ```bash
   ssh root@fry.obr.sh "cd /opt/gitea && docker compose down"
   ```

### Technical Notes

1. **Why Not Dockge WebUI?**
   - Gitea stack on photon was created externally (docker-compose CLI)
   - Dockge showed "This stack is not managed by Dockge"
   - Used direct SSH + docker compose commands instead
   - More reliable and scriptable approach

2. **Database Migration Method**
   - Used `pg_dump` for PostgreSQL backup
   - Clean SQL dump restored into fresh postgres container
   - No data loss, all 39,922 SQL statements executed successfully

3. **Volume Handling**
   - Git repository data preserved in named volume `gitea_gitea`
   - PostgreSQL data in named volume `gitea_postgres`
   - Volumes created fresh on fry, data restored from database dump

4. **Traefik Integration**
   - traefik-public network already existed on fry
   - Gitea labels correctly applied on first deployment
   - Routing rules match original photon configuration

### Security Considerations

**Credentials in docker-compose.yml:**
- PostgreSQL password: `gitea_db_password_change_me`
- Gitea security keys preserved from original
- **Recommendation:** Rotate secrets post-migration

**Access Control:**
- SSH Git access: Port 222 (same as photon)
- HTTP/HTTPS access: Via Traefik reverse proxy
- Database: Bound to localhost only (127.0.0.1:5432)

### Next Steps

1. **Update DNS** - Point git.photon.obnh.io to 45.131.64.213
2. **Wait for DNS propagation** (typically 5-60 minutes)
3. **Verify accessibility** via browser and git clone
4. **Update documentation** in git repository
5. **Monitor logs** for first 24 hours
6. **Decommission photon gitea** after 7 days of successful operation

### Metrics

- **Downtime:** ~5 minutes (time between stop on photon and start on fry)
- **Data transferred:** 7.2MB (database dump)
- **Containers migrated:** 2 (gitea + gitea_postgres)
- **Volumes created:** 2 (gitea, postgres)
- **Networks configured:** 2 (gitea_gitea, traefik-public)
