Inspect Volcano workloads faster with Headlamp

Volcano is a cloud-native batch scheduler for Kubernetes, designed for high-performance computing, AI/ML, and other batch workloads. Kubernetes was originally built for long-running services, whereas batch workloads often require dynamic job arrival, resource competition, and co-starting multiple workers. Volcano extends Kubernetes with concepts like queues, priorities, quotas, and gang scheduling, treating workloads as a whole rather than independent Pods. The Volcano plugin for Headlamp, an extensible Kubernetes web UI, brings these scheduling details into a single interface.The plugin provides dedicated views for Volcano Jobs, Queues, and PodGroups, making it easier to operate and troubleshoot batch workloads. The Job view displays workload status, task details, Pod status, and allows direct actions like suspending/resuming and accessing logs. The Queue view offers insights into resource allocation, capacity, and reservation details. The PodGroup view clarifies gang scheduling states and potential blockers.A key feature is the map view, which visually represents how Jobs, Queues, PodGroups, and Pods are interconnected, helping to quickly identify issues in pending or non-progressing workloads. This plugin enhances the interactive troubleshooting experience by centralizing related resources, structured details, and runtime output, without replacing CLI tools for automation. Future enhancements may include Prometheus integration and richer scheduling insights. Users can install the plugin via Headlamp's Plugin Catalog and provide feedback to shape its development.
