Types

type Loopback

type Loopback struct {
}

Loopback is a network strategy that provides a basic loopback device

func (*Loopback) Create

func (l *Loopback) Create(n *libcontainer.Network, nspid int, context libcontainer.Context) error

func (*Loopback) Initialize

func (l *Loopback) Initialize(config *libcontainer.Network, context libcontainer.Context) error

type NetNS

type NetNS struct {
}

crosbymichael: could make a network strategy that instead of returning veth pair names it returns a pid to an existing network namespace

func (*NetNS) Create

func (v *NetNS) Create(n *libcontainer.Network, nspid int, context libcontainer.Context) error

func (*NetNS) Initialize

func (v *NetNS) Initialize(config *libcontainer.Network, context libcontainer.Context) error

type NetworkStrategy

type NetworkStrategy interface {
	Create(*libcontainer.Network, int, libcontainer.Context) error
	Initialize(*libcontainer.Network, libcontainer.Context) error
}

NetworkStrategy represents a specific network configuration for a container's networking stack

func GetStrategy

func GetStrategy(tpe string) (NetworkStrategy, error)

GetStrategy returns the specific network strategy for the provided type. If no strategy is registered for the type an ErrNotValidStrategyType is returned.

type Veth

type Veth struct {
}

Veth is a network strategy that uses a bridge and creates a veth pair, one that stays outside on the host and the other is placed inside the container's namespace

func (*Veth) Create

func (v *Veth) Create(n *libcontainer.Network, nspid int, context libcontainer.Context) error

func (*Veth) Initialize

func (v *Veth) Initialize(config *libcontainer.Network, context libcontainer.Context) error
