AddRouteViaInterface is a function for Adding a route via gateway ex: ip route add 192.0.2.0/25 dev eth0

func RemoveVethFromOVS

func RemoveVethFromOVS(lu netlink.LinkUpdate) bool

RemoveVethFromOVS remove the veth from the ovs. We get the veth name from the netlink.LinkUpdate and traverse all OpenvSwitches and try to remove the veth from its parent OVS return true will stop the netlink server handler

func SetupVeth

func SetupVeth(contVethName, hostVethName string, mtu int, hostNS ns.NetNS) (net.Interface, net.Interface, error)

SetupVeth sets up a pair of virtual ethernet devices. Call SetupVeth from inside the container netns. It will create both veth devices and move the host-side veth into the provided hostNS namespace. On success, SetupVeth returns (hostVeth, containerVeth, nil)

Types

type NlEventHandler

type NlEventHandler struct {
	LinkDeleteHandler []linkReceiver
	// contains filtered or unexported fields
}

NlEventHandler is the structure for netlink event handler

func New() *NlEventHandler

New will return an new netlink event handler

func (*NlEventHandler) AddDeletedLinkHandler

func (nl *NlEventHandler) AddDeletedLinkHandler(handler linkReceiver)

AddDeletedLinkHandler will add DeletedLinkHandler

func (*NlEventHandler) Stop

func (nl *NlEventHandler) Stop()
