feat(k8s): replace API server watch with kubelet /pods polling #2369

vimalk78 · 2025-12-12T13:44:45Z

Reduces API server load on large clusters by polling local kubelet /pods endpoint instead of maintaining persistent watch connections.

Add kubeletPodInformer that polls kubelet at NODE_IP:10250/pods
Use downward API (status.hostIP) to get node IP
Add nodes/proxy RBAC for kubelet webhook authorization
Keep apiserver mode as fallback via kube.podInformer.mode config

Add kubeletPodInformer as an alternative to the API server watch-based informer. It polls the local kubelet /pods endpoint, reducing API server load. The kubelet host and port are auto-discovered from the Node object at startup. Key changes: - Add kubelet pod informer with singleflight-coalesced refresh, projected SA token rotation, and context-aware HTTP requests - Auto-discover kubelet endpoint from Node.Status.DaemonEndpoints and Node.Status.Addresses (InternalIP) - Add configurable podInformer mode ("kubelet" or "apiserver") with validation - Grant nodes/proxy RBAC permission for kubelet webhook authorization - Update all config files, manifests, Helm chart, and documentation
