func Cleanup ¶

func Cleanup(tapDevice string) error

Types ¶

type DynamicNetwork ¶

type DynamicNetwork struct {
}

func (DynamicNetwork) NetworkSetup ¶

func (n DynamicNetwork) NetworkSetup(uid uint32, gid uint32) (*UnikernelNetworkInfo, error)

NetworkSetup checks if any tap device is available in the current netns. If it is, it assumes a running unikernel is present in the current netns and returns an error, because network functionality for more than one unikernels is not yet implemented. If no TAP devices are available in the current netns, it creates a new tap device and sets TC rules between the veth interface and the tap device inside the namespace.

FIXME: CUrrently only one tap device per netns can provide functional networking. We need to find a proper way to handle networking for multiple unikernels in the same pod/network namespace. See: https://github.com/urunc-dev/urunc/issues/13

type Interface ¶

type Interface struct {
	IP             string
	DefaultGateway string
	Mask           string
	Interface      string
	MAC            string
}

type Manager ¶

type Manager interface {
	NetworkSetup(uid uint32, gid uint32) (*UnikernelNetworkInfo, error)
}

func NewNetworkManager ¶

func NewNetworkManager(networkType string) (Manager, error)

type StaticNetwork ¶

type StaticNetwork struct {
}

func (StaticNetwork) NetworkSetup ¶

func (n StaticNetwork) NetworkSetup(uid uint32, gid uint32) (*UnikernelNetworkInfo, error)

type UnikernelNetworkInfo ¶

type UnikernelNetworkInfo struct {
	TapDevice string
	EthDevice Interface
}
