The article focuses on providing a diagnostic approach to understand the root causes of such pending jobs. It introduces the concept of tracing the Kueue admission process as a key method for investigation. Specifically, the post identifies Headlamp as a tool that can be utilized to perform this tracing. By leveraging Headlamp, developers and operators can gain insights into the admission flow of Kueue, thereby identifying bottlenecks or issues preventing Kubernetes Jobs from being scheduled and executed. This approach aims to help users troubleshoot and resolve instances where their Kubernetes Jobs are not progressing from a pending status.
