* Flex drivers by default do not produce metrics. Flex plugins can enable metrics collection by setting  the capability 'supportsMetrics' to true. Make sure the file system can support fs stat to produce metrics in this case. ([#67508](https://github.com/kubernetes/kubernetes/pull/67508), [@brahmaroutu](https://github.com/brahmaroutu))

- Remove a v1alpha1 networking API for ClusterCIDRConfig ([#109436](https://github.com/kubernetes/kubernetes/pull/109436), [@JamesLaverack](https://github.com/JamesLaverack))
- Renamed metrics `evictions_number` to `evictions_total` and mark it as stable. The original `evictions_number` metrics name is marked as "Deprecated" and has been removed in kubernetes 1.23 .

你还可能有**其他原因**，这将使你更容易拥有一个带有**多个进程**的**单个容器**，而不是拥有每个容器中都有**单个进程**的**多个容器**。

例如（取决于你的设置）你可以在同一个容器中拥有一些工具，例如 Prometheus exporter，该工具应该有权访问**每个请求**。

在这种情况下，如果你有**多个容器**，默认情况下，当 Prometheus 来**读取metrics**时，它每次都会获取**单个容器**的metrics（对于处理该特定请求的容器），而不是获取所有复制容器的**累积metrics**。

在这种情况， 这种做法会更加简单：让**一个容器**具有**多个进程**，并在同一个容器上使用本地工具（例如 Prometheus exporter）收集所有内部进程的 Prometheus 指标并公开单个容器上的这些指标。

- When metrics are counted, discard the wrong container StartTime metrics ([#110880](https://github.com/kubernetes/kubernetes/pull/110880), [@yangjunmyfm192085](https://github.com/yangjunmyfm192085)) [SIG Instrumentation and Node]

number of workers used for replication defaults to 100. Based on network bandwidth and system load, the number of workers used in replication can be configured using `mc admin config set alias api` to set the `replication_workers`. The prometheus metrics exposed by MinIO can be used to plan resource allocation and bandwidth management to optimize replication speed.

If synchronous replication is configured above, replication is attempted right away prior to returning the PUT object response....
