### 2. Run MinIO in federated mode

Bucket lookup from DNS federation requires two dependencies

- etcd (for bucket DNS service records)
- CoreDNS (for DNS management based on populated bucket DNS service records, optional)

## Architecture

- Upgrade CoreDNS to v1.12.4 ([#133968](https://github.com/kubernetes/kubernetes/pull/133968), [@yashsingh74](https://github.com/yashsingh74)) [SIG Cloud Provider and Cluster Lifecycle]
