Build flock Image / build (push) Has been cancelled
Agent now watches nodeconfigs.flock.fritzlab.net via a client-go dynamic informer, filters events to its own node name, and caches the typed NodeConfig in memory (NodeConfigCache, atomic pointer). M2's IPAM will read from that cache. - pkg/agent/nodeconfig.go: informer + JSON-round-trip decode (avoids hand-written DeepCopy + scheme registration for this small a use). - pkg/agent/server.go: starts the informer goroutine; Run terminates if the informer returns. - pkg/api/v1alpha1: switch placeholder TypeMeta/ObjectMeta to metav1. - deploy/rbac: get/list/watch on nodeconfigs. - cmd/flock-agent: --kubeconfig flag for out-of-cluster runs (tests). Satisfies M1 verified-by: "kubectl apply NodeConfig; agent logs read it". Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>
