Single-node VictoriaMetrics stores metrics in its own data directory; no SQL Datastore is needed. Keep ingestion private unless an external agent must reach it.

## Towbar manifest

```yaml title=".towbar/services/victoriametrics.service.yml" theme={"system"}
id: victoriametrics
name: VictoriaMetrics
buildServer: null
deployment:
  type: image
  image: victoriametrics/victoria-metrics:v1.152.0
container:
  port: 8428
  network: application
  volumes:
    - name: victoria-metrics-data
      mountPath: /victoria-metrics-data
      initialData: image
environments:
  production:
    server: 192.0.2.10
rollout:
  type: recreate
  maintenanceMode: true
  reason: Persistent application data uses a single writer
```

## Configure

1. Prepare the example server, connect the repository, and map `production` to the branch containing these manifests. Replace the example server IP. Commit the manifests, then sync the repository and inspect the resolved configuration.
2. Keep the Service's named volumes attached across deployments. Towbar's Datastore backup policy does not back up Service volumes, so include them in your own recovery plan.
3. This manifest has no public domain. Use a trusted connection to the server for the first check. Add a public route only after configuring the product's authentication or an access gateway.
4. Deploy the Service, then perform the checks below before enabling auto-deploy.

## Verify

From a trusted client on the same application network, write a sample metric and query it back. Add an authenticated route only if external agents need access; check retention and the volume before treating this as a production metrics store.

For field constraints, see [Service manifest](/docs/services/manifest).
