### Environment variables

#### MINIO_ETCD_ENDPOINTS

This is comma separated list of etcd servers that you want to use as the MinIO federation back-end. This should
be same across the federated deployment, i.e. all the MinIO instances within a federated deployment should use same
etcd back-end.

```
KEY:
notify_kafka[:name]  publish bucket notifications to Kafka endpoints

ARGS:
brokers*         (csv)       comma separated list of Kafka broker addresses
topic            (string)    Kafka topic used for bucket notifications
sasl_username    (string)    username for SASL/PLAIN or SASL/SCRAM authentication

| policy     | _string_ or _[]string_ or _comma_separated_value_ | Canned policy name to be applied for STS credentials. (Mandatory) - This can be configured to any desired value such as `roles` or `groups` by setting the environment variable `MINIO_IDENTITY_OPENID_CLAIM_NAME` |

To add a replication rule allowing both delete marker replication, versioned delete replication or both specify the --replicate flag with comma separated values as in the example below.

```
KEY:
etcd  federate multiple clusters for IAM and Bucket DNS

ARGS:
endpoints*       (csv)       comma separated list of etcd endpoints e.g. "http://localhost:2379"
path_prefix      (path)      namespace prefix to isolate tenants e.g. "customer1/"
coredns_path     (path)      shared bucket DNS records, default is "/skydns"

# a local build cache:
TFCI=py312,linux_x86_cuda,public_cache,disk_cache ci/official/wheel.sh

# First, set your TFCI variable to choose the environment settings.
#   TFCI is a comma-separated list of filenames from the envs directory, which
#   are all settings for the scripts. TF's CI jobs are all made of a combination
#   of these env files.

Assuming that you already have Apache Kafka configured and running.
