setting the `UnauthenticatedHTTP2DOSMitigation` feature gate to `true` (it is disabled by default). An API server fronted by an L7 load balancer that already mitigates these http/2 attacks may choose not to enable the kube-apiserver mitigation to avoid disrupting load balancer → kube-apiserver connections if http/2 requests from multiple clients share the same backend connection. An API server on a private network may choose not to enable the kube-apiserver mitigation to prevent performance regressions...

  on the node's primary IPv4 and/or IPv6 address (according to the Node object).
  This is strongly recommended, if you were not previously using
  --nodeport-addresses, to avoid surprising behavior.
  (This behavior is enabled by default with the nftables backend; you would
  need to explicitly request `--nodeport-addresses 0.0.0.0/0,::/0` there to get

- When feature gate `JobTrackingWithFinalizers` is enabled:
  - Limit the number of Pods tracked in a single Job sync to avoid starvation of small Jobs.

in production environments carries significant risk. - Read the release notes for MinIO *before* performing any upgrade, there is no forced requirement to upgrade to latest release upon every release. Some release may not be relevant to your setup, avoid upgrading production environments unnecessarily. - If you plan to use `mc admin update`, MinIO process must have write access to the parent directory where the binary is present on the host system. - `mc admin update` is not supported and should be...

	// can easily eat into the internode bandwidth. This function would be mostly

	// To avoid these problems we must split the work at scale. With 1000 node
