description: Checks for missing CPU limits in Kubernetes Deployments, which can lead to excessive CPU usage and affect other applications
|
|
impact: |
|
|
Missing CPU limits in Kubernetes Deployments can cause excessive CPU usage that can starve other applications, leading to performance degradation across the cluster.
|
|
remediation: |
|
|
Set CPU limits for all containers in Kubernetes Deployments to ensure fair CPU resource distribution and prevent performance issues.
