Functions

func AddFlatNetworkRouteToHost

func AddFlatNetworkRouteToHost(
	podNS ns.NetNS, flatNetworkIP net.IP, master string,
) error

AddFlatNetworkRouteToHost adds flatNetworkIP route to native CNI iface on host NS

Example: ip route add <FLAT_NETWORK_IP> dev <NATIVE_CNI_IFACE> src <HOST_IP>

func AddPodFlatNetworkCustomRoutes

func AddPodFlatNetworkCustomRoutes(podNS ns.NetNS, customRoutes []flv1.Route) error

AddPodFlatNetworkCustomRoutes adds user defined custom routes and host IP routes to pod NS

func AddPodKubeCIDRRoutes

func AddPodKubeCIDRRoutes(podNS ns.NetNS, cidr string) error

func AddPodNodeCIDRRoutes

func AddPodNodeCIDRRoutes(podNS ns.NetNS) error

func CheckRouteExists

func CheckRouteExists(
	route *netlink.Route,
) (bool, error)

CheckRouteExists checks whether the route exists by route dst

func DelFlatNetworkRouteFromHost

func DelFlatNetworkRouteFromHost(flatNetworkIP net.IP) error

DelFlatNetworkRouteFromHost remove flatNetworkIP route from native CNI iface on host NS

Example: ip route del <FLAT_NETWORK_IP>

func EnsureRouteExists

func EnsureRouteExists(
	route *netlink.Route,
) error

EnsureRouteExists adds route if not exists

func GetDefaultLinkIDSet

func GetDefaultLinkIDSet() (map[int]bool, error)

func GetDefaultRoutes

func GetDefaultRoutes() ([]netlink.Route, error)

GetDefaultRoute gets default route NOTE: will return nil if no route found

func GetRouteByIP

func GetRouteByIP(ip net.IP) (*netlink.Route, error)

GetRouteByIP executes 'ip route get <IP>' on host network NS. NOTE: will return nil if no route found

func UpdatePodDefaultGateway

func UpdatePodDefaultGateway(
	podNS ns.NetNS, ifName string, flatNetworkIP net.IP, gateway net.IP,
) error
