hard📝 Best Practice Q15 of 15

Kubernetes - Production Best Practices

ACluster Autoscaler with properly set pod resource requests and limits

BManual node scaling with no pod resource limits

CDisable Horizontal Pod Autoscaler and increase node count permanently

DSet pod resource limits to zero and rely on node autoscaling

Step-by-Step Solution

Solution:

Step 1: Understand cluster autoscaling
Cluster Autoscaler adjusts node count based on pod scheduling needs and resource requests.
Step 2: Importance of pod resource requests and limits
Proper requests and limits let the autoscaler know actual resource needs to scale nodes efficiently.
Step 3: Evaluate other options
Manual scaling wastes resources; disabling HPA or zero limits causes inefficiency or errors.
Final Answer:
Cluster Autoscaler with properly set pod resource requests and limits -> Option A
Quick Check:
Autoscaler + resource requests = cost savings [OK]

Quick Trick: Use Cluster Autoscaler plus pod requests/limits for best cost control [OK]

Common Mistakes:

Relying on manual scaling only
Disabling autoscaling features
Setting resource limits to zero
