For testing purposes, here is [how to create self-signed certificates](https://github.com/minio/minio/tree/master/docs/tls#3-generate-self-signed-certificates).

## 2. Create Kubernetes secret

[Kubernetes secrets](https://kubernetes.io/docs/concepts/configuration/secret) are intended to hold sensitive information.

maintained, and supported. MinIO does not guarantee support for any given bug, feature request, or update referencing this chart. <br/><br/> MinIO publishes a separate [MinIO Kubernetes Operator and Tenant Helm Chart](https://github.com/minio/operator/tree/master/helm) that is officially maintained and supported. MinIO strongly recommends using the MinIO Kubernetes Operator for production deployments. See [Deploy Operator With Helm](https://min.io/docs/minio/kubernetes/upstream/operations/install-de...

Following is a sample directory structure for MinIO server with TLS certificates.

```sh
$ mc tree --files ~/.minio
/home/user1/.minio
└─ certs
   ├─ CAs
   ├─ private.key
   └─ public.crt
```

You can provide a custom certs directory using `--certs-dir` command line option.

#### Credentials

- Helm Chart: MinIO Helm Chart offers customizable and easy MinIO deployment with a single command. Refer [MinIO Helm Chart documentation](https://github.com/minio/minio/tree/master/helm/minio) for more details.

## Monitoring MinIO in Kubernetes

By default, MinIO shards the objects across N/2 data and N/2 parity drives. Though, you can use [storage classes](https://github.com/minio/minio/tree/master/docs/erasure/storage-class) to use a custom configuration. We recommend N/2 data and parity blocks, as it ensures the best protection from drive failures.

export MINIO_STORAGE_CLASS_STANDARD=EC:3
export MINIO_STORAGE_CLASS_RRS=EC:2
```

Storage class can also be set via `mc admin config` get/set commands to update the configuration. Refer [storage class](https://github.com/minio/minio/tree/master/docs/config#storage-class) for
more details.

#### Note

### Change default FTP port

Default port '8021' can be changed via

```
--ftp="address=:3021"
```

### Change FTP passive port range

By default FTP requests OS to give a free port automatically, however you may want to restrict
this to specific ports in certain restricted environments via

```
--ftp="passive-port-range=30000-40000"
```

### Change default SFTP port

  - [Deployment based on Kubernetes](https://min.io/docs/minio/kubernetes/upstream/index.html#quickstart-for-kubernetes)
  - [Deployment based on MinIO Helm Chart](https://github.com/helm/charts/tree/master/stable/minio)
