InformationLimit the rate at which the API server accepts requests.
Using 'EventRateLimit' admission control enforces a limit on the number of events that the API Server will accept in a given time slice. In a large multi-tenant cluster, there might be a small percentage of misbehaving tenants which could have a significant impact on the performance of the cluster overall. Hence, it is recommended to limit the rate of events that the API server will accept.
Note: This is an Alpha feature in the Kubernetes 1.8 release.
SolutionFollow the Kubernetes documentation and set the desired limits in a configuration file.
Then, edit the API server pod specification file '/etc/kubernetes/manifests/kube-apiserver.yaml' and set the below parameters.
You need to carefully tune in limits as per your environment.
