multus
<XXX: add ToC>
- Multus is a latin word for "Multi"
- As the name suggests, it acts as a Multi plugin in Kubernetes and provides the multiple network interface support in a pod
- This project is a reference implementation for Kubernetes Network Custom Resource Definition De-facto Standard. For more information refer Network Plumbing Working Group Agenda
- Reference implementation support following modes as "section 3.2 Network Object Definition" in the spec
- CNI config JSON in network object
- Not using CNI config (“thick” plugin usecase)
- CNI configuration stored in on-disk file
refer the section 3.2 Network Object Definition for more details in Kubernetes Network Custom Resource Definition De-facto Standard
- Multus supports all reference plugins (eg. Flannel, DHCP, Macvlan) that implement the CNI specification and all 3rd party plugins (eg. Calico, Weave, Cilium, Contiv). In addition to it, Multus supports SRIOV, SRIOV-DPDK, OVS-DPDK & VPP workloads in Kubernetes with both cloud native and NFV based applications in Kubernetes
- The default network gets "eth0" and additional network Pod interface name as “net0”, “net1”,… “netX and so on. Multus also support interface names from the user.
- Multus is one of the projects in the Baremetal Container Experience kit.
This is the example pod with multus. The pod has three interface: eth0, net0 and net1. eth0 connects kubernetes cluster network to connect with kubernetes server/services (e.g. kubernetes api-server, kubelets and so on). net0 and net1 are network attachment and connect to other networks with other CNI networks (e.g. vlan/vxlan/ptp).
Current version of multus-cni is '3.1'. v3.0 and above are not compatible with v1.0 and v2.0 version Network Object CRD.
