#### Etcd

MinIO supports storing encrypted IAM assets in etcd, if KMS is configured. Please refer to how to encrypt your config and IAM credentials [here](https://github.com/minio/minio/blob/master/docs/kms/IAM.md).

The wrapper will handle all serialization and de-seralization of the request and response,
and furthermore provides reuse of the structs used for the request and response.

Note that Responses sent for serialization are automatically reused for similar requests.
If the response contains shared data it will cause issues, since each unique response is reused.

          items:
          - key: public.crt
            path: public.crt
          - key: private.key
            path: private.key
          - key: public.crt
            path: CAs/public.crt
```

Note that the `secretName` should be same as the secret name created in previous step. Then add the below section under
`spec.containers[].volumeMounts[]`

```yaml
    volumeMounts:
        - name: secret-volume

			Optional:    true,
			Type:        "duration",
		},
		config.HelpKV{
			Key:         apiODirect,
			Description: "set to enable or disable O_DIRECT for writes under special conditions. NOTE: do not disable O_DIRECT without prior testing" + defaultHelpPostfix(apiODirect),
			Optional:    true,
			Type:        "boolean",
		},
		config.HelpKV{
			Key:         apiRootAccess,

	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, ""))
	}

		Help:      "Total number of bytes sent to the other peer nodes",
		Type:      counterMetric,
	}
}

func getInterNodeReceivedBytesMD() MetricDescription {
	return MetricDescription{
		Namespace: interNodeMetricNamespace,
		Subsystem: trafficSubsystem,
		Name:      receivedBytes,
		Help:      "Total number of bytes received from other peer nodes",
		Type:      counterMetric,
	}
}

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:
  - targets: ['server1:9000','server2:9000','server3:9000','server4:9000']
```
