eksctl inserts settings.interruptionQueueName value to Helm charts values during Karpenter installation. But this helm value has been renamed to settings.interruptionQueue (without "Name") at the end.
As a result, INTERRUPTION_QUEUE environment value is not passed to karpenter pods and the queue is not enabled. After fix (rename value name), INTERRUPTION_QUEUE appears in pod environment variables.
Suggested fix
Rename settings.interruptionQueueName to settings.interruptionQueue in user-provided Helm values when installing Karpenter.
