API-initiated eviction is the process by which you use the Eviction API to create an
|
||
Eviction object that triggers graceful pod termination.

API-initiated eviction is the process by which you use the [Eviction API](/docs/reference/generated/kubernetes-api/{{<param "version">}}/#create-eviction-pod-v1-core)
|
||
to create an `Eviction` object that triggers graceful pod termination.

|
||
API 发起的驱逐是一个先调用
|
||
[Eviction API](/docs/reference/generated/kubernetes-api/{{<param "version">}}/#create-eviction-pod-v1-core)
|
||
创建 `Eviction` 对象，再由该对象体面地中止 Pod 的过程。

<!--
|
||
You can request eviction either by directly calling the Eviction API
|
||
using a client of the kube-apiserver, like the `kubectl drain` command.
|
||
When an `Eviction` object is created, the API server terminates the Pod.
|
||
|
||
API-initiated evictions respect your configured [`PodDisruptionBudgets`](/docs/tasks/run-application/configure-pdb/)
|
||
and [`terminationGracePeriodSeconds`](/docs/concepts/workloads/pods/pod-lifecycle#pod-termination).
|
||
|
||
API-initiated eviction is not the same as [node-pressure eviction](/docs/concepts/scheduling-eviction/node-pressure-eviction/).
|
||
-->
|
||
你可以通过 kube-apiserver 的客户端，比如 `kubectl drain` 这样的命令，直接调用 Eviction API 发起驱逐。
|
||
当 `Eviction` 对象创建出来之后，该对象将驱动 API 服务器终止选定的 Pod。
|
||
|
||
API 发起的驱逐取决于你配置的 [`PodDisruptionBudgets`](/zh-cn/docs/tasks/run-application/configure-pdb/)
|
||
和 [`terminationGracePeriodSeconds`](/zh-cn/docs/concepts/workloads/pods/pod-lifecycle#pod-termination)。
|
||
|
||
API 发起的驱逐不同于[节点压力引发的驱逐](/zh-cn/docs/concepts/scheduling-eviction/node-pressure-eviction/)。
