NFV Partner Engineering along with the Network Plumbing Working Group is using Multus as part of a reference implementation. Multus CNI is a “meta plugin” for https://github.com/intel/multus-cni Kubernetes CNI which enables one to attach multiple network interfaces on each pod. It allows one to assign a CNI plugin to each interface created in the pod. 23
THE PROBLEM (Today) #1 Each pod only has one #2 Each master/node has only network interface one static CNI configuration Kubernetes Kubernetes Master/Node Master/Node so. static. Pod A eth0 flannel 24
THE SOLUTION (Today) Static CNI configuration points Each subsequent CNI plugin, as called by Multus, has to Multus configurations which are defined in CRD objects Kubernetes Kubernetes Master/Node Master/Node CRDs Pod annotation I’d like a flannel interface, and a macvlan interface please. flannel macvlan Pod C eth0 net0 flannel macvlan Sure thing bud, I’ll pull up the configurations stored in CRD objects. 25
