QoS Class of a Pod is set at creation time based on its compute resources requests and limits settings. QoS classes are used to make decisions about Pods scheduling and eviction.
|
|||
|
|
Kubernetes can assign one of the following QoS classes to a Pod: `Guaranteed`, `Burstable` or `BestEffort`.
|
|||

|
|||
|
|
Pod 的 QoS 类是基于 Pod 在创建时配置的计算资源请求和限制。QoS 类用于制定有关 Pod 调度和逐出的决策。
|
|||
|
|
Kubernetes 可以为 Pod 分配以下 QoS 类：`Guaranteed`，`Burstable` 或者 `BestEffort`。
