Build flock Image / build (push) Has been cancelled
agent: maintain NetworkUnavailable=False on owned nodes
When Calico shuts down on a flock-labeled node, calico-node sets
NetworkUnavailable=True with reason CalicoIsDown. Nothing replaces it,
so kubelet's NodeController applies node.kubernetes.io/network-
unavailable:NoSchedule and new pods can't land.

flock-agent now patches Status.Conditions every 60s with
NetworkUnavailable=False (reason=FlockReady). RBAC: nodes/status patch.

flock

Kubernetes CNI for sjc001. Per-pod IPv4 opt-in, IID embedding, Ready-gated anycast via BGP.

Design doc: k8s-manager/dfritz-cni.md (in the operator's k8s-manager repo).

Status: M1 scaffold. Not functional. See milestones table in the design doc.

Layout

  • cmd/flock — CNI plugin binary (kubelet-invoked)
  • cmd/flock-agent — DaemonSet binary
  • pkg/api/v1alpha1NodeConfig CRD types
  • pkg/cni — CNI plugin internals + RPC client
  • pkg/agent — agent server, IPAM, state file, anycast, NetworkPolicy
  • pkg/embedip-algo IID embedding (pure)
  • pkg/routing/{bird,ospf} — routing backends
  • deploy/ — CRDs, RBAC, DaemonSet manifests
