Question

我们已经在GCP上的kubernetes上运行我们的工作量大约一年了，但是，上周，我们的一个网站遭到了网站所有者推出的促销活动的严重打击，但没有我们预先设定群集。

从那时起，我们一直在测试群集上加载测试堆栈，我们遇到的问题是使用Google节点，HPA不会按照文档中的说明进行扩展，而是始终扩展

2 - ＆gt; 4 - ＆gt; 8 - ＆gt; 16 - ＆gt; 32 --64--128

无论CPU负载如何。

例如，在我们的测试中，我们有251％/ 60％的cpu，其中有8个pod正在运行。我的数学建议（251/60）* 8 =需要33个豆荚，但是，它总是会下一个16，然后等到3分钟再到32个。

测试运行所需的横向扩展大约是64个吊舱，它在大约25分钟后到达，而不是8个，有没有办法让GCP版本的操作更像手册？
