@@ -31,12 +31,24 @@ The installer creates:
- Environment file: `/etc/synapsis.env`
- Embedded Turso database: `/var/lib/synapsis/synapsis.db`
- Service: `synapsis.service`
- Mandatory update timer: `synapsis-update.timer`
Every node checks `origin/main` about once per minute. When a new commit is available, Synapsis fast-forwards the checkout, replaces the single `backups/latest` database snapshot, installs dependencies, runs migrations, builds, and restarts automatically. The currently deployed commit is shown in the Network Info card and exposed by `/api/version`.
For a node installed before automatic updates existed, bootstrap the timer once with:
```bash
sudo -u synapsis git -C /opt/synapsis pull --ff-only
sudo /opt/synapsis/deploy/update.sh
```
Useful commands:
```bash
sudo systemctl status synapsis
sudo systemctl status synapsis-update.timer
sudo journalctl -u synapsis -f
sudo journalctl -u synapsis-update -f
sudo /opt/synapsis/deploy/update.sh
sudo /opt/synapsis/deploy/uninstall.sh
```
