# Grafana auto-update setup

Grafana runs in Docker on a Synology NAS (192.168.1.30) via Container Manager.

## Prerequisites

The auto-update script SSHes into the Synology and runs `docker compose pull && up -d`. For this to work without sudo, the SSH user needs to be in the `docker` group.

### One-time Synology setup

```bash
ssh jeena@192.168.1.30
sudo synogroup --add docker
sudo synogroup --memberadd docker jeena
sudo chown root:docker /var/run/docker.sock
exit
```

Log out and back in (new SSH session) for the group to take effect. This persists through DSM updates and reboots.

### Verify

```bash
ssh jeena@192.168.1.30 '/usr/local/bin/docker ps'
```

Should list containers without permission errors.

## Notes

- Docker is at `/usr/local/bin/docker` on Synology (not in PATH for non-interactive SSH)
- The compose project is at `/volume1/docker/monitoring/`
- `context.txt` tells the AI classifier this is a simple Prometheus + Node Exporter setup with no plugins, so plugin-only breaking changes are classified as auto
