質問 # 23
Deploy Event Router and capture Kubernetes events in logging
Task Information : Deploy an event router so Kubernetes events are recorded as logs, then trigger events and confirm they appear in logging queries.
正解:
解説:
See the solution below in Explanation:
* Deploy event router resources
* Apply a deployment/serviceaccount/rolebinding manifest for eventrouter:
* oc apply -f eventrouter.yaml -n openshift-logging
* Eventrouter watches event API and writes them to stdout (collected by logging).
* Verify eventrouter pod is running
* oc -n openshift-logging get pods | grep -i event
* Trigger some events
* oc -n default run evtest --image=busybox --restart=Never -- sleep 1
* oc -n default delete pod evtest
* Creation/deletion generates events.
* Query logs for events
* In the logging UI/backend, search for the namespace/pod name evtest or eventrouter messages.
* Explanation: Validates that events are being converted to searchable logs.
質問 # 24
Prevent workloads from running on dedicated nodes (taints)
Task Information : Apply a taint to dedicated nodes so only pods with tolerations can run there.
正解:
解説:
See the solution below in Explanation:
Explanation:
* Taint nodes
* oc adm taint nodes worker-1 dedicated=payments:NoSchedule
* oc adm taint nodes worker-2 dedicated=payments:NoSchedule
* NoSchedule blocks new pods that do not tolerate the taint.
* Confirm taints
* oc describe node worker-1 | grep -i taints -A2
* Ensures taints are present.
* Validate effect
* A normal deployment without tolerations will remain Pending if it can only land on those tainted nodes.
質問 # 25
Add tolerations to a deployment
Task Information : Update payments/api deployment to tolerate dedicated=payments:NoSchedule.
正解:
解説:
See the solution below in Explanation:
Explanation:
* Patch deployment with toleration
* oc -n payments patch deploy api --type=merge -p '{
* "spec":{"template":{"spec":{"tolerations":[
* {"key":"dedicated","operator":"Equal","value":"payments","effect":"NoSchedule"}
* ]}}}
* }'
* Toleration allows pods to schedule onto tainted nodes.
* Verify scheduling
* oc -n payments get pods -o wide
質問 # 26
Silence an alert in Alertmanager
Task Information : Create an Alertmanager silence for a noisy alert for 2 hours, then confirm it's silenced.
正解:
解説:
See the solution below in Explanation:
Explanation:
* Find the alert name and labels
* Web console: Observe # Alerts # click the alert to view label set.
* Open Alertmanager silences
* Observe # Alerting # Alertmanager # Silences # Create silence
* Explanation: Silences mute alerts matching label filters.
* Create the silence
* Add matcher: alertname = < ALERT_NAME >
* Duration: 2 hours
* Save.
* Verify the alert shows as silenced
* The alert should indicate it is silenced in the UI.
質問 # 27
Spread replicas using podAntiAffinity
Task Information : Configure payments/api to prefer scheduling pods on different nodes.
正解:
解説:
See the solution below in Explanation:
Explanation:
* Patch deployment with preferred podAntiAffinity
* oc -n payments patch deploy api --type=merge -p '{
* "spec":{"template":{"spec":{"affinity":{
* "podAntiAffinity":{
* "preferredDuringSchedulingIgnoredDuringExecution":[{
* "weight":100,
* "podAffinityTerm":{
* "labelSelector":{"matchLabels":{"app":"api"}},
* "topologyKey":"kubernetes.io/hostname"
* }
* }]
* }
* }}}}
* }'
* Encourages spread across nodes to reduce single-node impact.
* Verify spread
* oc -n payments get pods -o wide
