Topic 1 · Question 14

SIMULATION - Task - From the pod label name=overloaded-cpu, find pods running high CPU workloads and write the name of the pod consuming most CPU to the file /opt/ KUTR00401/KUTR00401.txt (which already exists).

Suggested solution

mkdir -p /opt/KUTR00401
kubectl top pod -l name=overloaded-cpu --sort-by=cpu --no-headers | awk 'NR==1 {print $1}' > /opt/KUTR00401/KUTR00401.txt

kubectl top sorts matching Pods by CPU and the pipeline writes the highest consumer's name.
