질문 # 25
Kubeconfig Management - Set Credentials in Kubeconfig
정답：
설명：
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.
질문 # 26
Schedule a recurring backup
Task Information : Create a daily backup schedule for namespace orders at 01:00.
정답：
설명：
See the solution below in Explanation:
Explanation:
* Create the schedule
* velero schedule create orders-daily \
* --schedule "0 1 * * *" \
* --include-namespaces orders \
* --snapshot-volumes
* Cron format: minute hour day month weekday.
* Verify schedule exists
* velero schedule get
* Confirm backups are created by the schedule
* velero backup get | grep orders-daily
* Scheduled backups usually have names derived from the schedule.
질문 # 27
Configure BackupStorageLocation and VolumeSnapshotLocation
Task Information : Configure OADP/Velero storage locations and confirm they show as Available.
정답：
설명：
See the solution below in Explanation:
Explanation:
* Create a secret for cloud credentials (S3-compatible example)
* oc -n openshift-adp create secret generic cloud-credentials \
* --from-file=cloud=/path/to/credentials
* Velero uses this secret to authenticate to object storage.
* Create/Update the DataProtectionApplication (DPA)
* Apply a DPA CR that defines:
* backupLocations (bucket, endpoint URL, region, etc.)
* snapshotLocations (if using snapshots)
* Verify BackupStorageLocation and SnapshotLocation
* velero backup-location get
* velero snapshot-location get
* Status should be Available, meaning storage config is valid.

질문 # 28
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 # 29
Create and use client certificates with kubeconfig (CSR flow)
Task Information : Generate a client key/CSR for audit2, approve it, extract the signed cert, and build a kubeconfig using that cert.
정답：
설명：
See the solution below in Explanation:
Explanation:
* Generate private key and CSR
* openssl genrsa -out audit2.key 2048
* openssl req -new -key audit2.key -out audit2.csr -subj "/CN=audit2/O=auditors"
* CN becomes username; O can map to groups in some setups.
* Base64 encode CSR for the API object
* CSR=$(base64 -w0 audit2.csr)
* Kubernetes CSR object expects base64-encoded request data.
* Create the CSR object
* cat < < EOF | oc apply -f -
* apiVersion: certificates.k8s.io/v1
* kind: CertificateSigningRequest
* metadata:
* name: audit2-csr
* spec:
* request: ${CSR}
* signerName: kubernetes.io/kube-apiserver-client
* usages:
* - client auth
* EOF
* Approve the CSR
* oc adm certificate approve audit2-csr
* Approval triggers certificate issuance.
* Extract the signed certificate
* oc get csr audit2-csr -o jsonpath='{.status.certificate}' | base64 -d > audit2.crt
* Produces the client certificate file.
* Build kubeconfig using cert/key
* oc config set-credentials audit2 \
* --client-certificate=audit2.crt --client-key=audit2.key \
* --embed-certs=true --kubeconfig=audit2.kubeconfig
* oc config set-cluster lab \
* --server="$(oc whoami --show-server)" \
* --insecure-skip-tls-verify=true \
* --kubeconfig=audit2.kubeconfig
* oc config set-context audit2 \
* --cluster=lab --user=audit2 --namespace=default \
* --kubeconfig=audit2.kubeconfig
* Creates a kubeconfig that authenticates using client certificates.
* Test
* oc --kubeconfig=audit2.kubeconfig get ns
