NEW QUESTION # 27
Integrate OpenShift with Keycloak (OIDC)
Task Information : Add a Keycloak (RH SSO) OpenID Connect identity provider to OpenShift OAuth and verify redirect/login works.
Answer:
Explanation:
See the solution below in Explanation:
Explanation:
* Collect Keycloak details
* Issuer URL (realm), client ID, and client secret.
* Confirm Keycloak client has correct redirect URI for OpenShift OAuth callback.
* Create a secret with the OIDC client secret
* oc -n openshift-config create secret generic keycloak-oidc-secret \
* --from-literal=clientSecret=' < SECRET > '
* OAuth reads the OIDC client secret from this secret.
* Edit OAuth and add OpenID provider
* oc edit oauth cluster
Add under spec.identityProviders:
- name: keycloak
mappingMethod: claim
type: OpenID
openID:
issuer: "https://keycloak.example.com/realms/ocp"
clientID: "openshift"
clientSecret:
name: keycloak-oidc-secret
claims:
preferredUsername: ["preferred_username"]
name: ["name"]
email: ["email"]
* issuer must match Keycloak realm issuer URL.
* claims determines which token claims map to OpenShift username/name/email.
* Restart OAuth pods
* oc -n openshift-authentication delete pod -l app=oauth-openshift
* Verify by logging in through the web console
* You should be redirected to Keycloak, authenticate, then return to OpenShift.
* Confirm users/identities:
* oc get users
* oc get identities

Task Information : Create an Argo CD Application that syncs from Git into namespace gitops-demo with automated sync enabled.
Answer:
Explanation:
See the solution below in Explanation:
Explanation:
* Create target namespace
* oc new-project gitops-demo
* Destination must exist (unless Argo is configured to auto-create).
* Create Application manifest
* apiVersion: argoproj.io/v1alpha1
* kind: Application
* metadata:
* name: demo-app
* namespace: openshift-gitops
* spec:
* project: default
* source:
* repoURL: https://git.example.com/org/repo.git
* targetRevision: main
* path: manifests/demo
* destination:
* server: https://kubernetes.default.svc
* namespace: gitops-demo
* syncPolicy:
* automated:
* prune: true
* selfHeal: true
* automated: enables auto sync.
* prune: removes deleted objects from Git.
* selfHeal: corrects drift.
* Apply Application
* oc apply -f demo-app.yaml
* Verify sync health
* oc -n openshift-gitops get application demo-app -o yaml | grep -i -E "sync|health" -n
* oc -n gitops-demo get all
NEW QUESTION # 29
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.
Answer:
Explanation:
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.
NEW QUESTION # 30
GitOps and MachineConfig - Push MachineConfig to Git
Answer:
Explanation:
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.
NEW QUESTION # 31
Configure resiliency using a PodDisruptionBudget
Task Information : Ensure at least 2 replicas of payments/api remain available during voluntary disruptions.
Answer:
Explanation:
See the solution below in Explanation:
Explanation:
* Create PDB
* cat < < EOF | oc -n payments apply -f -
* apiVersion: policy/v1
* kind: PodDisruptionBudget
* metadata:
* name: api-pdb
* spec:
* minAvailable: 2
* selector:
* matchLabels:
* app: api
* EOF
* minAvailable: 2 blocks evictions that would reduce availability below 2.
* Verify PDB
* oc -n payments get pdb
* oc -n payments describe pdb api-pdb
