默认ack的apiserver qps是5，突发请求上限是10，如果你对于apiserver的请求qps大于这个值就会报错，所以我们需要修改节点池的kubelet参数

之前ack是不能直接在ack的管理面板上修改kubelet参数的，现在是直接可以修改了的

直接修改可以看

https://help.aliyun.com/document_detail/452567.html

但是如果你想使用脚本去修改ack的kubelet参数可以看看这个。

首先下载aliyun 的cli

wget https://github.com/aliyun/aliyun-cli/releases/download/v3.0.141/aliyun-cli-macosx-3.0.141-arm64.tgz

之后登陆验证

aliyun configure

➜  ~ aliyun configure
Configuring profile 'default' in 'AK' authenticate mode...
Access Key Id []: 
Access Key Secret []: 
Default Region Id []: 
Default Output Format [json]: json (Only support json)
Default Language [zh|en] en:
Saving profile[default] ...Done.

Configure Done!!!

➜  ~

接着就是修改节点池的参数

./aliyun cs PUT /clusters/集群id/nodepools/节点池id/node_config –body=’{“rolling_policy”: {“max_parallelism”: 10}, “kubelet_config”: {“kubeAPIQPS”:50,“kubeAPIBurst”:100}}'

其实就是一个put请求

最后你可以进节点中执行

ps -ef |grep kubelet

验证下是不是有对应的参数
