- This field is mandatory for standalone and erasure code MinIO server deployments, to enable federated mode.
- This field is optional for distributed deployments. If you don't set this field in a federated setup, we use the IP addresses of
hosts passed to the MinIO server startup and use them for DNS entries.

### Run Multiple Clusters

> cluster1

```sh

- Since we selected Copy mode when creating the SOBR, the backup will be copied to the capacity tier as soon as it is created on the performance tier.

- [Configuring etcd](https://github.com/minio/minio/blob/master/docs/sts/etcd.md)

### Setup MinIO with Identity Provider

Make sure we have followed the previous step and configured each software independently, once done we can now proceed to use MinIO STS API and MinIO server to use these credentials to perform object API operations.

#### KeyCloak

```
export MINIO_ROOT_USER=minio

## **4. Run Sample Applications**

After installing Hive, Hadoop and Spark successfully, we can now proceed to run some sample applications to see if they are configured appropriately.  We can use Spark Pi and Spark WordCount programs to validate our Spark installation. We can also explore how to run Spark jobs from the command line and Spark shell.

### **4.1 Spark Pi**

The user setting up replication needs *s3:GetReplicationConfiguration* and *s3:GetBucketVersioning* permission on the source cluster. We do not recommend running root credentials/super admin with replication, instead create a dedicated user. The access credentials used at the destination requires *s3:ReplicateObject* permission.

- `mc admin update` is not supported and should be avoided in kubernetes/container environments, please upgrade containers by upgrading relevant container images.
- **We do not recommend upgrading one MinIO server at a time, the product is designed to support parallel upgrades please follow our recommended guidelines.**

**In our tests we also found ext4 does not honor POSIX O_DIRECT/Fdatasync semantics, ext4 trades performance for consistency guarantees. Please avoid ext4 in your setup.**

### 2. Install boto3

Install `aws-sdk-python` from AWS SDK for Python official docs [here](https://aws.amazon.com/sdk-for-python/)

### 3. Example

 * Running on http://127.0.0.1:5000
Press CTRL+C to quit

## Start MinIO with Lambda target

Register MinIO with a Lambda function, we are calling our target name as `function`, but you may call it any other friendly name of your choice.
```
MINIO_LAMBDA_WEBHOOK_ENABLE_function=on MINIO_LAMBDA_WEBHOOK_ENDPOINT_function=http://localhost:5000 minio server /data &
