节点压力驱逐是 kubelet 主动使 Pod 失败以回收节点上的资源的过程。

Node-pressure eviction is the process by which the kubelet proactively fails
|
|
pods to reclaim resources on nodes.

The kubelet monitors resources like CPU, memory, disk space, and filesystem
|
|
inodes on your cluster's nodes. When one or more of these resources reach
|
|
specific consumption levels, the kubelet can proactively fail one or more pods
|
|
on the node to reclaim resources and prevent starvation.
|
|
-->
|
|
kubelet 监控集群节点上的 CPU、内存、磁盘空间和文件系统 inode 等资源。
|
|
当这些资源中的一个或多个达到特定消耗水平时，
|
|
kubelet 可以主动使节点上的一个或多个 Pod 失效，以回收资源并防止饥饿。
|

<!--

|
Node-pressure eviction is not the same as [API-initiated eviction](/docs/concepts/scheduling-eviction/api-eviction/).

|
|
节点压力驱逐不用于 [API 发起的驱逐](/zh-cn/docs/concepts/scheduling-eviction/api-eviction/)。
