- `aws:username` - This is a string containing the friendly name of the current user, this value would point to STS temporary credential in `AssumeRole`ed requests, use `jwt:preferred_username` in case of OpenID connect and `ldap:username` in case of AD/LDAP. *aws:userid* is an alias to *aws:username* in MinIO.

With NetworkPolicy enabled, traffic will be limited to just port 9000.

For more precise policy, set `networkPolicy.allowExternal=true`. This will
only allow pods with the generated client label to connect to MinIO.
This label will be displayed in the output of a successful install.

### Existing secret

Instead of having this chart create the secret for you, you can supply a preexisting secret, much

scrape_configs:
- job_name: minio-job-bucket
  metrics_path: /minio/v2/metrics/bucket
  scheme: http
  static_configs:
  - targets: ['localhost:9000']
```

##### 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

root credentials. You can use the Browser to create buckets, upload objects, and browse the contents of the MinIO server.

You can also connect using any S3-compatible tool, such as the MinIO Client `mc` commandline tool. See
[Test using MinIO Client `mc`](#test-using-minio-client-mc) for more information on using the `mc` commandline tool. For application developers,

client = mqtt.Client(client_id="myclientid",clean_session=False)

client.on_connect = on_connect
client.on_message = on_message

client.connect("localhost",1883,60)
client.loop_forever()
```

Execute this example python program to watch for MQTT events on the console.

```py
python mqtt.py
```

```

Following example shows connecting via ftp client using `minioadmin` credentials, and list a bucket named `runner`:

```
ftp localhost -P 8021
Connected to localhost.
220 Welcome to MinIO FTP Server
Name (localhost:user): minioadmin
331 User name ok, password required
Password:
230 Password ok, continue
Remote system type is UNIX.
Using binary mode to transfer files.

## Configuring Site Replication

- Configure an alias in `mc` for each of the sites. For example if you have three MinIO sites, you may run:

```sh

## **2. Prerequisites**

- Install Hortonworks Distribution using this [guide.](https://docs.hortonworks.com/HDPDocuments/Ambari-2.7.1.0/bk_ambari-installation/content/ch_Installing_Ambari.html)
  - [Setup Ambari](https://docs.hortonworks.com/HDPDocuments/Ambari-2.7.1.0/bk_ambari-installation/content/set_up_the_ambari_server.html) which automatically sets up YARN

**NOTE:**

```sh
openssl rsa -in private-pkcs8-key.key -aes256 -passout pass:PASSWORD -out private.key
```

#### 3.2.3 Generate a self-signed certificate

Create a file named `openssl.conf` with the content below. Set `IP.1` and/or `DNS.1` to point to the correct IP/DNS addresses:

```sh
[req]
distinguished_name = req_distinguished_name
x509_extensions = v3_req
prompt = no

[req_distinguished_name]
C = US
ST = VA
