Kubernetes水平Pod自动缩放初始延迟? [英] Kubernetes horizontal pod autoscaling initial delay?

问题描述

Kubernetes水平Pod自动缩放中是否配置了此功能，以指定在向上/缩小之前运行或创建的Pod的最小延迟?

Is their a configuration in Kubernetes horizontal pod autoscaling to specify a minimum delay for a pod to be running or created before scaling up/down?

例如，类似以下内容:

# I am looking for a flag like this
--horizontal-pod-autoscale-initial-upscale-delay=5m0s

# Similar to these existing flags
--horizontal-pod-autoscaler-downscale-delay=2m0s
--horizontal-pod-autoscaler-upscale-delay=2m0s

结果是:

• 等待5分钟，然后再出现任何高档
• 5分钟后，最多每2分钟执行一次降级操作

我遇到一种情况，即Pod在启动时会消耗大量资源进行引导(这是预期的)，但我不希望在此期间对其进行扩展，并且一旦完成引导程序，它就有资格进行自动扩展. /p>

I have a situation where a Pod consumes lots of resources on start-up for bootstrapping (which is expected) but I don't want it scaled during this time, and once bootstrap is done it may be eligible for autoscaling.

推荐答案

此标志实际上存在:--horizontal-pod-autoscaler-cpu-initialization-period 此外，您还需要考虑就绪延迟:--horizontal-pod-autoscaler-initial-readiness-delay和度量标准循环时间--horizontal-pod-autoscaler-sync-period，以计算总(最大/最小/平均)延迟.

This flag actually exists: --horizontal-pod-autoscaler-cpu-initialization-period In addition you need to consider the readiness delay: --horizontal-pod-autoscaler-initial-readiness-delay and the metric loop time, --horizontal-pod-autoscaler-sync-period to calculate the total (max/min/average) delay.
