Topic 1 · Question 9

SIMULATION - Task - Check to see how many nodes are ready (not including nodes tainted NoSchedule) and write the number to /opt/KUSC00402/kusc00402.txt.

Suggested solution

kubectl get nodes -o jsonpath='{range .items[?(@.status.conditions[?(@.type=="Ready")].status=="True")]}{.metadata.name}{"\t"}{.spec.taints}{"\n"}{end}' | grep -v 'NoSchedule' | wc -l > /opt/KUSC00402/kusc00402.txt

The command selects Ready nodes, excludes any with a NoSchedule taint, and writes only the count.
