You created a Kubernetes deployment by runningkubectl run nginx image=nginx replicas=1. After a few days, you decided you no longer want this deployment. You identified the pod and deleted it by running kubectl delete pod. You noticed the pod got recreated.

$ kubectl get pods

NAME READY STATUS RESTARTS AGE

nginx-84748895c4-nqqmt 1/1 Running 0 9m41s

$ kubectl delete pod nginx-84748895c4-nqqmt

pod nginx-84748895c4-nqqmt deleted

$ kubectl get pods

NAME READY STATUS RESTARTS AGE

nginx-84748895c4-k6bzl 1/1 Running 0 25s

D.
kubectl delete inginx
Answers
D.
kubectl delete inginx
Suggested answer: A

Explanation:

This command correctly deletes the deployment. Pods are managed by kubernetes workloads (deployments). When a pod is deleted, the deployment detects the pod is unavailable and brings up another pod to maintain the replica count. The only way to delete the workload is by deleting the deployment itself using the kubectl delete deployment command.

$ kubectl delete deployment nginx

deployment.apps nginx deleted
