如何修改kube-controller-manager连接APIserver的QPS

如何修改kube-controller-manager连接连接APIserver的QPS。

kube-controller-manager提供了对APIserver每秒查询速率的参数，可以直接修改kube-controller-manager的yaml文件，并重启对应pod。

1.修改yaml文件

# 配改配置
$ vim /etc/kubernetes/manifests/kube-controller-manager.yaml
    - --kube-api-qps=100

# 重启节点上的kubelet
$ systemctl restart kubelet

2.验证

$ kubectl get pod -A |grep kube-controller-manager
kube-system   kube-controller-manager-192.168.0.170                    1/1     Running   0               32s


$ ps -ef|grep kube-controller-manager
