…ummy interfaces This assumes that some other component (e.g. cilium) deploys a configmap which contains the mapping from cluster node to shadow range. The configmap must be accessible to the Kubelet (can be done e.g. by deploying a daemonset which mounts the ConfigMap as a volume on the target nodes) The script expects the configmap to have a field for each target node. The contents of each field are expected to be JSON with keys indicating the interface prefix and the values being objects with fields "base", "from" and "to" which can be used to construct the shadow egress IPs in the range by iterating from "from" to "to" and using each value generated by the iteration as the suffix to "base" (note that this currently assumes that each egress range is fully contained in a /24).
