Summary

  • Remove hardcoded devices/directRoutingDevice from Cilium install — auto-detect per node for heterogeneous NICs (eno1 vs enP7s7)
  • Set k8sServiceHost=127.0.0.1 k8sServicePort=6444 so Cilium init containers reach API via k3s agent's local LB proxy (port 6444, not 6443)
  • Add node-role.kubernetes.io/worker label to agent config so workers show role in kubectl get nodes

Test plan

  • Tested live: DGX Spark (aarch64, Ubuntu, enP7s7) joined worker0-k8s0 cluster as worker
  • Both nodes Ready, all Cilium pods Running

- Remove hardcoded devices/directRoutingDevice from Cilium install (let
  Cilium auto-detect per node — needed for heterogeneous NICs like eno1 vs enP7s7)
- Set k8sServiceHost=127.0.0.1 k8sServicePort=6444 so Cilium init
  containers can reach the API via k3s agent's local LB proxy
- Add node-role.kubernetes.io/worker label to agent config
