Introduction

Validates whether you limit the maximum allowed CPU usage for your Kubernetes resources. Limiting CPU usage prevents utilizing the entire available CPU, which may cause stability issues for other Kubernetes resources.

Supported Advice States

Action Needed

Automatically discovers whether all Kubernetes container's resources.limits.cpu are configured. The discovery is performed by the open-source library kube-score and integrated into this advice.

Validation Needed

Asks you to validate with an automatically created experiment that provided features work as expected, fail gracefully, workload resources scale up or monitoring alerts while consuming a lot of CPU.

Implemented

Once the Kubernetes container's specification resources.limits.cpu configures a value that was marked as validated.
