Question #: 7
Topic #: 1
The installation of a Cloud Pak for Integration operator is hanging and the administrator needs to debug it. Which objects on the OpenShift cluster should be checked first?
A.
The Log Aggregator in the openshift-operators namespace and then the subscription.
B.
The InstallPlan and the pod logs from the hanging operator.
C.
The operator's Subscription. InstallPlan. and ClusterServiceVersion.
D.
The ibm-operator-catalog CatalogSource and the ClusterServiceVersion.
When installing an IBM Cloud Pak for Integration (CP4I) operator in an OpenShift cluster, issues like hanging installations often occur due to problems with the Operator Lifecycle Manager (OLM). The best approach for debugging a stalled installation is to systematically check the key Operator OLM objects in the following order:
Subscription:
The Subscription (Subscription CR) manages the operator installation and upgrades.
Check if the subscription is in the correct state (kubectl get subscription -n ).
Look for events that might indicate why the operator is stuck.
InstallPlan:
The InstallPlan determines the installation process for the operator.
If an InstallPlan is pending, it might indicate that dependencies or permissions are missing.
Use kubectl get installplan -n to check its status.
ClusterServiceVersion (CSV):
The ClusterServiceVersion (CSV) represents the installed operator and its status.
If the CSV is in a "Pending" or "Failed" state, logs will provide insights into what is wrong.
Use kubectl get csv -n to check its status.
Option A (Log Aggregator in openshift-operators and then Subscription) – Incorrect:
While logging is useful, the first step should be checking the OLM objects like Subscription, InstallPlan, and CSV.
Option B (InstallPlan and pod logs from the hanging operator) – Incorrect:
The InstallPlan is useful, but checking Subscription and CSV as well is necessary for a complete diagnosis.
Checking pod logs is a later step, not the first thing to do.
Option D (ibm-operator-catalog CatalogSource and ClusterServiceVersion) – Incorrect:
The CatalogSource is used to fetch the operator package, but it is not the first thing to check.
Checking Subscription, InstallPlan, and CSV first provides a more direct way to diagnose the issue.
