A county deploys metrics-server and must raise replicas and resource requests without forking upstream YAML by hand each time. Which Kustomize approach fits cluster-component customization?
Select an answer to reveal the explanation.
Short Explanation
Kustomize overlays are like sticky notes on the vendor instructions—same base, your local tweaks for replicas and CPU. You keep upstream readable and your county’s patches in one place. Hand-editing production every quarter is how configs drift into folklore.
Full Explanation
Kustomize overlays patch base manifests for environment-specific settings such as replica counts and resource requests without maintaining a full divergent fork. That pattern fits CKA’s use of Kustomize for cluster components like metrics-server. Unrecorded live edits make upgrades and audits harder.
