25. Frage
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.
Antwort:
Begründung:
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.
26. Frage
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.
Antwort:
Begründung:
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.
27. Frage
Resolve group synchronization conflicts (prune stale data)
Task Information : Run group sync with pruning to remove stale OpenShift group memberships that no longer exist in LDAP.
Antwort:
Begründung:
See the solution below in Explanation:
Explanation:
* Run group sync with prune controls
* oc adm groups sync --sync-config=groupsync.yaml --confirm --prune-whitelist=/tmp/whitelist.txt
* Prune removes stale memberships/groups, but whitelist protects selected groups from pruning.
* Verify group membership reflects LDAP
* oc describe group < groupname >
* Confirms removed users are no longer listed.
28. Frage
GitOps and MachineConfig - Push MachineConfig to Git
Antwort:
Begründung:
See the solution below in Explanation:
Explanation:
Step 1: Make sure the MachineConfig YAML has already been created or modified in the local Git repository.
This Task assumes the file change is ready to be committed.
Step 2: Run the command:
git commit -am "Add MachineConfig for motd" & & git push origin main
Step 3: Verify the commit succeeds and the push goes to the main branch.
The lab output shows:
[main 8d32a1] Add MachineConfig for motd
Detailed explanation:
This Task is part of a GitOps workflow. Instead of manually applying changes directly to the cluster, the desired configuration is stored in Git, and a GitOps controller such as Argo CD synchronizes the cluster to match the repository state. The command commits all tracked modified files with the message Add MachineConfig for motd and then pushes the change to the main branch. In this model, Git becomes the source of truth. A MachineConfig is typically used to manage node-level operating system configuration in OpenShift, so pushing it through GitOps ensures the change is auditable, repeatable, and reconciled declaratively. If the commit does not include the intended YAML, the synchronization mechanism will not apply the desired change.
29. Frage
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.
Antwort:
Begründung:
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.
