질문 # 16
Integrate OpenShift with LDAP (create LDAP identity provider)
Task Information : Configure cluster OAuth to add an LDAP identity provider using an existing bind secret and CA ConfigMap , then verify login works.
정답：
설명：
See the solution below in Explanation:
Explanation:
* Verify prerequisites exist (Secret + ConfigMap)
* oc -n openshift-config get secret rhds-ldap-secret
* oc -n openshift-config get configmap rhds-ca-config-map
* OAuth LDAP configuration references these objects. If they don't exist, OAuth won't be able to bind to LDAP securely.
* Edit the cluster OAuth resource
* oc edit oauth cluster
* The oauth/cluster resource is where identity providers are defined.
* Add an LDAP identity provider entry (example structure) Add under spec.identityProviders:
* - name: corp-ldap
* mappingMethod: claim
* type: LDAP
* ldap:
* url: "ldaps://ldap.example.com:636/ou=People,dc=example,dc=com?uid"
* bindDN: "uid=openshift,ou=svc,dc=example,dc=com"
* bindPassword:
* name: rhds-ldap-secret
* ca:
* name: rhds-ca-config-map
* insecure: false
* attributes:
* id: ["dn"]
* name: ["cn"]
* preferredUsername: ["uid"]
* email: ["mail"]
* url: where to search for users and which attribute is used for login (here uid).
* bindDN + bindPassword: service account used for LDAP queries.
* ca: trusts the LDAP server CA for TLS.
* attributes: maps LDAP data into OpenShift user identity fields.
* Restart OAuth pods to load changes quickly
* oc -n openshift-authentication delete pod -l app=oauth-openshift
* This forces pods to restart and re-read the updated configuration.
* Verify the identity provider appears and users can log in
* In the web console login page, you should see the new provider (name may show as corp-ldap).
* After a successful login, confirm user objects appear:
* oc get users
* oc get identities
* OpenShift creates User and Identity objects upon first successful authentication.
질문 # 17
Identity Management - Create HTPasswd Secret
정답：
설명：
See the solution below in Explanation:
Explanation:
Step 1: Open a terminal with oc access to the cluster.
This Task is CLI-driven and targets the openshift-config namespace.
Step 2: Run the command:
oc create secret generic rhds-ldap-secret --from-literal bindPassword=redhatocp -n openshift-config Step 3: Verify that the secret is created successfully.
The lab output shows:
secret/rhds-ldap-secret created
Detailed explanation:
This step creates a generic secret named rhds-ldap-secret in the openshift-config namespace. The secret stores a key called bindPassword with the value redhatocp. In an identity-provider or LDAP integration workflow, the bind password is used by OpenShift when connecting to the external directory service. Storing this value in a secret is the correct operational pattern because authentication material should not be embedded directly into configuration objects. The openshift-config namespace is specifically important because cluster authentication configuration commonly references secrets and configmaps from that namespace. If the secret name or key is wrong, the authentication configuration that depends on it may fail to validate or connect properly.
질문 # 18
Dedicate nodes to a workload using labels and nodeSelector
Task Information : Label two nodes with workload=payments and schedule a deployment only onto those nodes.
정답：
설명：
See the solution below in Explanation:
Explanation:
* Label the chosen worker nodes
* oc label node worker-1 workload=payments
* oc label node worker-2 workload=payments
* Node labels are key/value metadata used by the scheduler.
* Add a nodeSelector to the deployment
* oc -n payments patch deploy api --type=merge -p '{
* "spec":{"template":{"spec":{"nodeSelector":{"workload":"payments"}}}}
* }'
* Forces pods to schedule only to nodes that match the label.
* Verify placement
* oc -n payments get pods -o wide
* Confirms pods are running on the intended nodes.
질문 # 19
Restore application into same namespace
Task Information : Restore from backup orders-full and validate the app resources return.
정답：
설명：
See the solution below in Explanation:
Explanation:
* Start the restore
* velero restore create orders-restore --from-backup orders-full
* Monitor restore status
* velero restore get
* velero restore describe orders-restore --details
* Validate restored resources
* oc -n orders get all
* oc -n orders get pvc
* Ensure deployments/pods/services and PVCs exist and pods become Running.
질문 # 20
Configure project-wide default tolerations
Task Information : Configure the payments namespace so new pods automatically include a default toleration.
정답：
설명：
See the solution below in Explanation:
Explanation:
* Annotate the namespace with default tolerations
* oc annotate ns payments \
* scheduler.alpha.kubernetes.io/defaultTolerations='[{"key":"dedicated","operator":"Equal","value":" payments","effect":"NoSchedule"}]' \
* --overwrite
* Some clusters honor this pattern; if not, the fallback is mutating admission or editing workloads.
* Create a new pod/deployment in the namespace
* Then verify its spec includes tolerations:
* oc -n payments get pod < pod > -o yaml | grep -n tolerations -A5
