問題 #29
Configure log forwarding to an external endpoint
Task Information : Configure Cluster Logging to forward application logs to an external output using ClusterLogForwarder.
答案：
解題說明：
See the solution below in Explanation:
Explanation:
* Verify logging namespace and resources
* oc get ns openshift-logging
* oc -n openshift-logging get clusterlogforwarder
* ClusterLogForwarder configures pipelines and outputs.
* Create/Edit ClusterLogForwarder (example structure)
* Define an output (external system) and pipeline selecting application logs.
* Apply via YAML:
* oc -n openshift-logging apply -f clusterlogforwarder.yaml
* Validate collector pods are healthy
* oc -n openshift-logging get pods
* Forwarding relies on collectors (vector/fluentd depending config).
* Generate a test log line
* oc -n openshift-logging run logger --image=busybox --restart=Never -- /bin/sh -c 'echo hello- forwarding; sleep 5'
* This creates a known message to search in the external endpoint.
* Confirm logs arrive at destination
* Use your external system's query/search to confirm hello-forwarding.
問題 #30
Kubeconfig Management - Use Context
答案：
解題說明：
See the solution below in Explanation:
Explanation:
Step 1: Make sure the context already exists in the kubeconfig file.
This follows the context creation Task SIMULATION .
Step 2: Run the command:
oc config use-context audit --kubeconfig audit.config
Step 3: Confirm the active context switches successfully.
The lab output shows:
Switched to context "audit".
Detailed explanation:
This command activates the audit context inside the specified kubeconfig file. Once selected, subsequent oc commands using that kubeconfig will default to the cluster, user, and namespace associated with that context.
This is operationally important because many administration mistakes come from running commands against the wrong cluster or project. Using explicit context switching reduces that risk and makes the kubeconfig usable for the intended audit workflow. In exams and real environments alike, the context is what turns separate kubeconfig elements into a working session configuration. Without switching to the correct context, even a well-formed kubeconfig may not be used as expected.
問題 #31
Export and import a Kubernetes application (YAML export)
Task Information : Export typical app objects from orders and apply them into a new namespace orders- copy.
答案：
解題說明：
See the solution below in Explanation:
Explanation:
* Export objects to YAML
* oc -n orders get deploy,svc,route,cm,secret -o yaml > orders-app.yaml
* Exports key application resources.
* Create target namespace
* oc new-project orders-copy
* Apply exported YAML
* oc -n orders-copy apply -f orders-app.yaml
* Recreates resources (some fields may need adjustment, like namespaces or immutable fields).
* Validate
* oc -n orders-copy get all
問題 #32
Logging Configuration - Configure ClusterLogging in Web Console
答案：
解題說明：
See the solution below in Explanation:
Explanation:
Step 1: Log in to the OpenShift web console.
This Task is explicitly defined as a GUI workflow.
Step 2: Navigate to Operators .
Installed logging components are managed through the operator framework.
Step 3: Open Installed Operators .
This lists operators already deployed in the cluster.
Step 4: Select Red Hat OpenShift Logging .
This operator manages the cluster logging stack and its custom resources.
Step 5: Open the ClusterLogging instance.
The Task SIMULATION refers to editing the existing ClusterLogging custom resource.
Step 6: Switch to YAML View .
This allows direct editing of the logging custom resource specification.
Step 7: Edit the collection type and set it to vector.
This changes the log collector implementation.
Step 8: Click Save .
The operator will reconcile the resource and apply the updated collector configuration.
Detailed explanation:
The ClusterLogging custom resource controls the logging stack behavior in OpenShift. Changing the collection type to vector updates which collector technology is used for gathering node and container logs. In operator-managed platforms, direct YAML edits to the custom resource are the preferred method for changing managed behavior because the operator then applies and maintains the desired state. This Task tests both navigation skills in the web console and knowledge of where logging behavior is configured. Saving the resource triggers reconciliation, which is a core OpenShift operator pattern: the declared configuration is read and enforced by the operator rather than by manual per-pod changes.
問題 #33
Create a full application backup (resources + PV data)
Task Information : Create a Velero backup of namespace orders including PV snapshots.
答案：
解題說明：
See the solution below in Explanation:
Explanation:
* Confirm resources and PVCs exist
* oc -n orders get all
* oc -n orders get pvc
* Ensures there is something meaningful to back up.
* Create backup including volume snapshots
* velero backup create orders-full --include-namespaces orders --snapshot-volumes
* Captures Kubernetes objects and requests PV snapshots where supported.
* Check status/details
* velero backup describe orders-full --details
* velero backup logs orders-full
* Review warnings/errors and confirm snapshot actions.
