##### Node (optional)

Optionally you can also collect per node metrics. This needs to be done on a per server instance.
The scrape configurations should use all the servers under `targets` so that graphing systems like
grafana can visualize them for all the nodes

```yaml
scrape_configs:
- job_name: minio-job
  metrics_path: /minio/v2/metrics/node
  scheme: http
  static_configs:

	envValues := make(map[string]string, len(envs))
	for _, envK := range envs {
		// skip certain environment variables as part
		// of the whitelist and could be configured
		// differently on each nodes, update skipEnvs()
		// map if there are such environment values
		if _, ok := skipEnvs[envK]; ok {
			continue
		}
		envValues[envK] = logger.HashString(env.Get(envK, ""))
	}

```bash
helm install --set persistence.enabled=false minio/minio
```

### Existing PersistentVolumeClaim

If a Persistent Volume Claim already exists, specify it during installation.
