質問 # 11
Configure log forwarding to an external endpoint
Task Information : Configure Cluster Logging to forward application logs to an external output using ClusterLogForwarder.
正解：
解説：
See the solution below in Explanation:
Explanation:
* Verify logging namespace and resources
* oc get ns openshift-logging
* oc -n openshift-logging get clusterlogforwarder
* ClusterLogForwarder configures pipelines and outputs.
* Create/Edit ClusterLogForwarder (example structure)
* Define an output (external system) and pipeline selecting application logs.
* Apply via YAML:
* oc -n openshift-logging apply -f clusterlogforwarder.yaml
* Validate collector pods are healthy
* oc -n openshift-logging get pods
* Forwarding relies on collectors (vector/fluentd depending config).
* Generate a test log line
* oc -n openshift-logging run logger --image=busybox --restart=Never -- /bin/sh -c 'echo hello- forwarding; sleep 5'
* This creates a known message to search in the external endpoint.
* Confirm logs arrive at destination
* Use your external system's query/search to confirm hello-forwarding.

Kubeconfig Management - Set Credentials in Kubeconfig
正解：
解説：
See the solution below in Explanation:
Explanation:
Step 1: Ensure the client certificate and private key files are available.
The lab uses audit.crt and tls.key.
Step 2: Run the command:
oc config set-credentials audit --client-certificate audit.crt --client-key tls.key --embed-certs --kubeconfig audit.config Step 3: Confirm the user entry is written.
The lab output shows:
User "audit" set.
Detailed explanation:
This command creates or updates the audit user entry inside the kubeconfig file audit.config. It points the user to a client certificate and private key, and the --embed-certs option stores certificate material directly inside the kubeconfig rather than only referencing external files. That makes the kubeconfig more portable because it can be moved and used without separately copying the certificate files, provided the embedded content is valid. In certificate-based authentication, the private key proves client possession while the certificate presents the approved identity. If the certificate and key do not match, authentication will fail. This step does not yet define what cluster or namespace the user works against; it only defines the credential identity.
質問 # 13
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 # 14
Maintain group synchronization on a schedule (CronJob)
Task Information : Create a CronJob that runs LDAP group sync on a schedule using a service account that has the required permissions.
正解：
解説：
See the solution below in Explanation:
Explanation:
* Create a namespace for the sync job
* oc new-project id-sync
* Keeps the automation components organized.
* Create a service account for the sync job
* oc -n id-sync create sa group-sync
* CronJob runs under this SA identity.
* Grant cluster permissions to manage groups
* oc adm policy add-cluster-role-to-user cluster-admin system:serviceaccount:id-sync:group-sync
* In real environments you should scope down, but lab Task SIMULATIONs often accept cluster- admin for speed.
* Create a ConfigMap for groupsync.yaml and Secret(s) for bind password/CA
* Mount them into the job container.
* Create CronJob to run group sync
* Command inside job:
* oc adm groups sync --sync-config=/config/groupsync.yaml --confirm
* The CronJob ensures periodic reconciliation with LDAP.
* Verify job runs
* oc -n id-sync get cronjob
* oc -n id-sync get jobs
* oc -n id-sync logs job/ < job-name >
質問 # 15
Create and use a service account token via kubeconfig
Task Information : Create SA ci-bot in ci namespace and generate a kubeconfig that authenticates using its token.
正解：
解説：
See the solution below in Explanation:
Explanation:
* Create namespace and service account
* oc new-project ci
* oc -n ci create sa ci-bot
* The SA will represent automation access.
* Grant permissions (example: edit in namespace)
* oc -n ci policy add-role-to-user edit system:serviceaccount:ci:ci-bot
* Without permissions, token auth succeeds but API actions are denied.
* Generate token (TokenRequest)
* TOKEN=$(oc -n ci create token ci-bot)
* OCP issues a short-lived token by default (good practice).
* Create kubeconfig using the token
* oc config set-cluster lab --server="$(oc whoami --show-server)" \
* --insecure-skip-tls-verify=true --kubeconfig=ci-bot.kubeconfig
* oc config set-credentials ci-bot --token="$TOKEN" --kubeconfig=ci-bot.kubeconfig
* oc config set-context ci --cluster=lab --user=ci-bot --namespace=ci \
* --kubeconfig=ci-bot.kubeconfig
* oc config use-context ci --kubeconfig=ci-bot.kubeconfig
* This produces a self-contained kubeconfig for CI automation.
* Test access
* oc --kubeconfig=ci-bot.kubeconfig get pods
