description: Checks for missing CPU requests in Kubernetes Deployments, which can lead to inadequate scheduling and resource allocation.
|
|
impact: |
|
|
Missing CPU requests in Kubernetes Deployments can cause poor scheduling decisions and suboptimal resource allocation, potentially leading to degraded application performance.
|
|
remediation: |
|
|
Set CPU requests for all containers in Kubernetes Deplayments to ensure efficient scheduling and resource allocation.
