Volumes

Host Path	Container Path	Type	Notes
/home/clint/containers/syncthing/config	/var/syncthing/config	Local ext4	Config, certs, keys, database index (~1.4 GB)
/home/clint/archive/systems/containers/syncthing	/var/syncthing/data	CIFS mount	Synced data from NAS (//192.168.69.2/archive)

CIFS Mount Dependency

The data volume requires the CIFS mount to be active. If the mount is down, Syncthing will fail to start or lose access to synced files.

# /etc/fstab entry
//192.168.69.2/archive /home/clint/archive cifs rw,credentials=/etc/samba_credentials,iocharset=utf8,vers=3.0,uid=1000,gid=1000,dir_mode=0775,file_mode=0775,_netdev 0 0

Permissions: uid=1000,gid=1000,file_mode=0775,dir_mode=0775 — matches clint user and allows read/write from the container.

Important Notes

• Uses the official syncthing/syncthing image, NOT the linuxserver variant. The official image uses /var/syncthing/config and /var/syncthing/data paths (linuxserver uses /config, /data1, /data2).
• No PUID/PGID environment variables — the official image handles user mapping differently.
• Healthcheck: curl -f http://127.0.0.1:8384/ — uses 127.0.0.1 not localhost (Alpine IPv6 resolves localhost to ::1).
• Traefik routing is managed by Coolify (Docker labels), not by manual traefik-custom.yml entries.

Deployment

Managed by Coolify. Start/stop via Coolify UI or API:

# Start
curl -X POST http://192.168.69.4:2010/api/v1/services/wg4gc4k48k00s484ksswwg44/start \
  -H "Authorization: Bearer <token>"

# Stop
curl -X POST http://192.168.69.4:2010/api/v1/services/wg4gc4k48k00s484ksswwg44/stop \
  -H "Authorization: Bearer <token>"

Disaster Recovery

If Coolify is lost but data survives:

cd /home/clint/containers/syncthing
sudo docker compose up -d

This standalone compose will start Syncthing with the same config and data paths. Traefik routing would need to be re-added manually to traefik-custom.yml.
