PWC: Pod with Resource Limits — DevOps Interview Q&A (2026)

Pod with Resource Limits

Beginner Mode

Start your terminal to use beginner mode.

An application needs guaranteed resources and limits to prevent overconsumption.

Create a pod with resource requests and limits configured.

Step 1: Generate pod template

kubectl run resource-pod --image=nginx:latest --dry-run=client -o yaml > pod.yaml

Step 2: Edit pod.yaml to add resources

Add under containers[0]:

    resources:
      requests:
        cpu: 100m
        memory: 64Mi
      limits:
        cpu: 200m
        memory: 128Mi

Step 3: Apply and verify

kubectl apply -f pod.yaml
kubectl describe pod resource-pod | grep -A6 "Limits\|Requests"
