afxdp-network-operator

The AF_XDP Network Operator is designed to help the user to provision and configure AF_XDP CNI plugin and Device plugin in a K8s cluster.

Motivation

AF_XDP requires a number of components in order to be provisioned and configured appropriately. An operator is a natural choice for a central point to coordinate the relevant components in one place.

Goals

• To provision, advertise and manage a set of interfaces for Pods that want to use AF_XDP.
• Pods should be able to run without any special privileges.
• Pods should be able to take advantage of PFs, VFs and SFs.
• To interwork with BPFd (eBPF lifecycle management daemon).

Targetted Functionality

• Initialize the supported AF_XDP NIC types on selected nodes.
• Provision/upgrade AF_XDP device plugin executable on selected node.
• Provision/upgrade AF_XDP CNI plugin executable on selected nodes.
• Manage configuration of AF_XDP device plugin on host.
• Generate net-att-def CRs for AF_XDP CNI plugin
• Work with BPFd to load and unload BPF progs on the netdevs
• Supports operation in a virtualized Kubernetes deployment - Needs more investigation
