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:

# 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

   # Should show Gitea login page
   curl -L https://git.photon.obnh.io
   

2. Git Operations Test

   # 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:

   ssh root@photon.obnh.io "cd /opt/gitea && docker compose up -d"
   

2. Verify services:

   ssh root@photon.obnh.io "docker ps | grep gitea"
   

3. DNS remains unchanged (points to photon)

4. Stop containers on fry:

   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)
