EX280 Cluster Installation And Management Practice Question
An administrator is troubleshooting an Operator installed via OperatorHub whose pods are failing to pull images because the Operator's subscription namespace lacks access to the global pull secret. How can the administrator configure OLM to use a custom pull secret for an Operator in a specific namespace?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Add the image pull secret to the ServiceAccount used by the Operator deployment in the target namespace.
Administrators can link a pull secret to the ServiceAccount used by the Operator's CSV or patch the operator's deployment/subscription depending on OLM version, or add the pull secret to the default ServiceAccount in that namespace.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Modify the global ClusterVersion resource with the namespace-specific pull secret.
Why it's wrong here
Global cluster pull secrets apply cluster-wide and do not support per-namespace custom overrides directly through ClusterVersion.
- ✗
Edit the CatalogSource resource to inject credentials into the CSV.
Why it's wrong here
CatalogSources provide package manifests, not namespace pod pull credentials.
- ✗
Annotate the OperatorGroup with 'olm.openshift.io/pull-secret=true'.
Why it's wrong here
OperatorGroups do not support pull-secret annotations.
- ✓
Add the image pull secret to the ServiceAccount used by the Operator deployment in the target namespace.
Why this is correct
Kubernetes pods pull images using credentials attached to their ServiceAccount via imagePullSecrets.
