description: Checks for missing memory requests in Kubernetes Deployments, which can lead to inefficient scheduling and potential node resource exhaustion.
|
|
impact: |
|
|
Missing memory requests in Kubernetes Deployments can lead to inefficient pod scheduling, causing potential resource exhaustion on nodes.
|
|
remediation: Set memory requests for all containers in Kubernetes Deployments to ensure efficient pod scheduling and node resource utilization.
