## Publish MinIO events via Webhooks

[Webhooks](https://en.wikipedia.org/wiki/Webhook) are a way to receive information when it happens, rather than continually polling for that data.

### Step 1: Add Webhook endpoint to MinIO

- `kube-apiserver` updated:

### DaemonSet
* **[beta]** Introduce the rolling update feature for DaemonSet. See [Performing a Rolling Update on a DaemonSet](https://kubernetes.io/docs/tasks/manage-daemon/update-daemon-set/).

### Deployment

* The `kubectl rolling-update` is now deprecated.  Use `kubectl rollout` instead.  ([#61285](https://github.com/kubernetes/kubernetes/pull/61285), [@soltysh](https://github.com/soltysh))
