Headlamp Plugin for Karpenter: Real-Time Autoscaling Visibility

Karpenter autoscaling shouldn't be a mystery.

The new Headlamp plugin for Karpenter brings real-time visibility to your cluster's scaling behavior. See which instances are being provisioned, why pending pods can't schedule, and track NodeClaims as they spin up and down.

What you get:

• Live metrics: Resource usage, disruption limits, provisioning latency
• Scaling decisions: Understand exactly why Karpenter chose each instance type
• Pending pod dashboard: See unmet scheduling requirements at a glance
• Config editor: Edit Karpenter settings with validation and diff previews
• Resource relationships: Map how NodeClasses, NodePools, and NodeClaims connect to your Kubernetes objects

Built as a LFX mentor project, the plugin currently works best with AWS and Azure providers, though it should handle most Karpenter setups.

Debugging autoscaling issues? This changes how you troubleshoot. Stop guessing, start seeing.
