질문 # 15
Export and import a Kubernetes application (YAML export)
Task Information : Export typical app objects from orders and apply them into a new namespace orders- copy.
정답：
설명：
See the solution below in Explanation:
Explanation:
* Export objects to YAML
* oc -n orders get deploy,svc,route,cm,secret -o yaml > orders-app.yaml
* Exports key application resources.
* Create target namespace
* oc new-project orders-copy
* Apply exported YAML
* oc -n orders-copy apply -f orders-app.yaml
* Recreates resources (some fields may need adjustment, like namespaces or immutable fields).
* Validate
* oc -n orders-copy get all
질문 # 16
Kubeconfig Management - Approve CSR
정답：
설명：
See the solution below in Explanation:
Explanation:
Step 1: Identify the pending certificate signing request.
The lab names it audit-csr.
Step 2: Run the approval command:
oc adm certificate approve audit-csr
Step 3: Confirm approval.
The lab output shows:
certificatesigningrequest.certificates.k8s.io/audit-csr approved
Detailed explanation:
In Kubernetes and OpenShift, a CSR must be approved before the requester can use the signed certificate for authentication. This Task approves the CSR named audit-csr, which is likely associated with the audit user or service account access flow in the lab. Certificate-based authentication is commonly used for kubeconfig access because it enables secure client identity without relying solely on tokens. Until the CSR is approved, the certificate cannot be trusted by the cluster API for authenticated operations. Administrative approval is therefore a gatekeeping step that ensures only intended certificate requests become valid credentials. This Task is part of a broader kubeconfig workflow that continues with setting credentials and defining context.
질문 # 17
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.
정답：
설명：
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.
질문 # 18
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.
정답：
설명：
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
질문 # 19
Kubeconfig Management - Use Context
정답：
설명：
See the solution below in Explanation:
Explanation:
Step 1: Make sure the context already exists in the kubeconfig file.
This follows the context creation Task SIMULATION .
Step 2: Run the command:
oc config use-context audit --kubeconfig audit.config
Step 3: Confirm the active context switches successfully.
The lab output shows:
Switched to context "audit".
Detailed explanation:
This command activates the audit context inside the specified kubeconfig file. Once selected, subsequent oc commands using that kubeconfig will default to the cluster, user, and namespace associated with that context.
This is operationally important because many administration mistakes come from running commands against the wrong cluster or project. Using explicit context switching reduces that risk and makes the kubeconfig usable for the intended audit workflow. In exams and real environments alike, the context is what turns separate kubeconfig elements into a working session configuration. Without switching to the correct context, even a well-formed kubeconfig may not be used as expected.
