Kubernetes CKA sample exam question 63 with answer

Question
Write a command into /opt/course/15/cluster_event.sh which shows the latest events in the whole cluster, ordered by time. Use kubectl for it.
Now kill the kube-proxy Pod running on node cluster2-worker1 and write the events this caused into /opt/course/15/pod_kill.log
Finally kill the containerd container of the kube-proxy Pod on node cluster2-worker1 and write the events into /opt/course/15/container_kill.log

Answer
For the first command you can grab the answer from Kubernetes documentation if you search for kubectl cheatsheet:

# List Events sorted by timestamp
kubectl get events -A --sort-by=.metadata.creationTimestamp

Create the shell file:

echo "kubectl get events -A --sort-by=.metadata.creationTimestamp" > /opt/course/15/cluster_event.sh

Test:

bash /opt/course/15/cluster_event.sh

Get pods running on kube-system namespace with extended details:

kubectl get po -n kube-system -o wide

Find the pod running on cluster2-worker1 and delete it and write the events:

kubectl -n kube-system delete po kube-proxy-wk5jt
kubectl -n kube-system get events > /opt/course/15/pod_kill.log

Next - login to cluster2-worker1 and kill the container:

ssh cluster2-worker1
creictl ps
crictl stop xxxxxxxx # id of the kube-proxy pod

Go back to the master and write events:

kubectl -n kube-system get events > /opt/course/15/container_kill.log

Analyze the logs:

cat /opt/course/15/pod_kill.log
cat /opt/course/15/container_kill.log
