質問 # 29
Integrate OpenShift with Keycloak (OIDC)
Task Information : Add a Keycloak (RH SSO) OpenID Connect identity provider to OpenShift OAuth and verify redirect/login works.
正解：
解説：
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
質問 # 30
Configure project-wide default tolerations
Task Information : Configure the payments namespace so new pods automatically include a default toleration.
正解：
解説：
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
質問 # 31
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.
正解：
解説：
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.
質問 # 32
Install OADP Operator and verify Velero components
Task Information : Install the OADP operator and confirm Velero pods/components are running.
正解：
解説：
See the solution below in Explanation:
Explanation:
* Install OADP via Web Console
* Operators # OperatorHub # search OADP / OpenShift API for Data Protection # Install
* Explanation: This operator manages Velero and backup integrations.
* Verify the operator CSV is installed
* oc get csv -A | grep -i -E "oadp|data protection|velero"
* Confirms installation succeeded.
* Verify pods in the OADP namespace (commonly openshift-adp)
* oc get pods -n openshift-adp
* You should see Velero/OADP-related pods in Running state.
質問 # 33
GitOps and MachineConfig - Push MachineConfig to Git
正解：
解説：
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.
