Functions

func GenerateContainerInterfaceKey

func GenerateContainerInterfaceKey(podName, podNamespace string) string

GenerateContainerInterfaceKey generates a unique string for a Pod interface as: pod/<Pod-Namespace-name>/<Pod-name>.

func GenerateContainerInterfaceName

func GenerateContainerInterfaceName(podName string, podNamespace string) string

GenerateContainerInterfaceName generates a unique interface name using the Pod's Namespace and name. The output should be deterministic (so that multiple calls to GenerateContainerInterfaceName with the same parameters return the same value). The output has the length of interfaceNameLength(15). The probability of collision should be neglectable.

func GenerateNodeTunnelInterfaceKey

func GenerateNodeTunnelInterfaceKey(nodeName string) string

GenerateNodeTunnelInterfaceKey generates a unique string for a Node's tunnel interface as: node/<Node-name>.

func GenerateNodeTunnelInterfaceName

func GenerateNodeTunnelInterfaceName(nodeName string) string

GenerateNodeTunnelInterfaceName generates a unique interface name for the tunnel to the Node, using the Node's name.

func GetIPNetDeviceFromIP

func GetIPNetDeviceFromIP(localIP net.IP) (*net.IPNet, netlink.Link, error)

GetIPNetDeviceFromIP returns a local IP/mask and associated device from IP.

func GetNetLink

func GetNetLink(dev string) netlink.Link

GetNetLink returns dev link from name.
