## How to enable Fan-Out Uploads ?

Fan-Out uploads are automatically enabled if `x-minio-fanout-list` form-field is provided with the PostUpload API, to keep things simple higher level APIs are provided in our SDKs for example in `minio-go` SDK:

[Grafana](https://grafana.com/) allows you to query, visualize, alert on and understand your metrics no matter where they are stored. Create, explore, and share dashboards with your team and foster a data driven culture.

## Prerequisites

## Get started

In this document we will explain in detail on how to configure multiple users.

### 1. Prerequisites

- Install mc - [MinIO Client Quickstart Guide](https://min.io/docs/minio/linux/reference/minio-mc.html#quickstart)

5)  Store the encrypted OEK encrypted data key and master key ID in object metadata.
 ```

Only the root/admin user can perform an SSE-S3 key rotation using the Admin-API via [mc](https://github.com/minio/mc). For more details about how to perform key management operations using the CLI refer to [mc admin guide](https://github.com/minio/mc/blob/master/docs/minio-admin-complete-guide.md) or run `mc admin kms key`.

#### Secure Erasure and Locking

# How to secure access to MinIO on Kubernetes with TLS [![Slack](https://slack.min.io/slack?type=svg)](https://slack.min.io)

This document explains how to configure MinIO server with TLS certificates on Kubernetes.

## 1. Prerequisites

- Familiarity with [MinIO deployment process on Kubernetes](https://min.io/docs/minio/kubernetes/upstream/operations/installation.html).

- Kubernetes cluster with `kubectl` configured.

### Certificate Directory

```
docker service create --name="minio-service" --secret="access_key" --secret="secret_key" quay.io/minio/minio server /data
```

Read more about `docker service` [here](https://docs.docker.com/engine/swarm/how-swarm-mode-works/services/)

```

Following example shows how to list an object and download it locally via `ftp` client:

```
ftp> ls runner/chunkdocs/metadata

MinIO's erasure coded backend uses high speed [HighwayHash](https://github.com/minio/highwayhash) checksums to protect against Bit Rot.
