virtual-kubelet

Overview ¶

Package main implements the virtual-kubelet executable for InterLink.

The Virtual Kubelet acts as a bridge between Kubernetes and external compute resources through the InterLink API. It creates a virtual node in the Kubernetes cluster that can schedule pods to remote execution environments.

Key features:

• Creates and manages a virtual node in Kubernetes
• Proxies pod operations to InterLink API
• Handles TLS/mTLS communication
• Supports WebSocket tunneling for port exposure
• Manages pod lifecycle and status updates
• Provides kubelet-compatible HTTP API endpoints

Usage:

virtual-kubelet -nodename <node-name> -configpath <config-file>

Environment Variables:

• NODENAME: Name of the virtual node (required)
• CONFIGPATH: Path to configuration file
• KUBECONFIG: Path to Kubernetes configuration
• KUBELET_URL: Virtual kubelet HTTP server bind address
• KUBELET_PORT: Virtual kubelet HTTP server port
• ENABLE_TRACING: Enable OpenTelemetry tracing (set to "1")
