Types

type Capability

type Capability struct {
	DataScope string
}

Capability represents the high level capabilities of the drivers which libnetwork can make use of

type DiscoveryType

type DiscoveryType int

DiscoveryType represents the type of discovery element the DiscoverNew function is invoked on

type Driver

type Driver interface {
	// CreateNetwork invokes the driver method to create a network passing
	// the network id and network specific config. The config mechanism will
	// eventually be replaced with labels which are yet to be introduced.
	CreateNetwork(nid string, options map[string]interface{}, ipV4Data, ipV6Data []IPAMData) error

	// DeleteNetwork invokes the driver method to delete network passing
	// the network id.
	DeleteNetwork(nid string) error

	// CreateEndpoint invokes the driver method to create an endpoint
	// passing the network id, endpoint id endpoint information and driver
	// specific config. The endpoint information can be either consumed by
	// the driver or populated by the driver. The config mechanism will
	// eventually be replaced with labels which are yet to be introduced.
	CreateEndpoint(nid, eid string, ifInfo InterfaceInfo, options map[string]interface{}) error

	// DeleteEndpoint invokes the driver method to delete an endpoint
	// passing the network id and endpoint id.
	DeleteEndpoint(nid, eid string) error

	// EndpointOperInfo retrieves from the driver the operational data related to the specified endpoint
	EndpointOperInfo(nid, eid string) (map[string]interface{}, error)

	// Join method is invoked when a Sandbox is attached to an endpoint.
	Join(nid, eid string, sboxKey string, jinfo JoinInfo, options map[string]interface{}) error

	// Leave method is invoked when a Sandbox detaches from an endpoint.
	Leave(nid, eid string) error

	// DiscoverNew is a notification for a new discovery event, Example:a new node joining a cluster
	DiscoverNew(dType DiscoveryType, data interface{}) error

	// DiscoverDelete is a notification for a discovery delete event, Example:a node leaving a cluster
	DiscoverDelete(dType DiscoveryType, data interface{}) error

	// Type returns the the type of this driver, the network type this driver manages
	Type() string
}

Driver is an interface that every plugin driver needs to implement.

type DriverCallback

type DriverCallback interface {
	// RegisterDriver provides a way for Remote drivers to dynamically register new NetworkType and associate with a driver instance
	RegisterDriver(name string, driver Driver, capability Capability) error
}

DriverCallback provides a Callback interface for Drivers into LibNetwork

type ErrActiveRegistration

type ErrActiveRegistration string

ErrActiveRegistration represents an error when a driver is registered to a networkType that is previously registered

func (ErrActiveRegistration) Error

func (ar ErrActiveRegistration) Error() string

Error interface for ErrActiveRegistration

func (ErrActiveRegistration) Forbidden

func (ar ErrActiveRegistration) Forbidden()

Forbidden denotes the type of this error

type ErrEndpointExists

type ErrEndpointExists string

ErrEndpointExists is returned if more than one endpoint is added to the network

func (ErrEndpointExists) Error

func (ee ErrEndpointExists) Error() string

func (ErrEndpointExists) Forbidden

func (ee ErrEndpointExists) Forbidden()

Forbidden denotes the type of this error

type ErrNoEndpoint

type ErrNoEndpoint string

ErrNoEndpoint is returned if no endpoint with the specified id exists

func (ErrNoEndpoint) Error

func (ene ErrNoEndpoint) Error() string

func (ErrNoEndpoint) NotFound

func (ene ErrNoEndpoint) NotFound()

NotFound denotes the type of this error

type ErrNoNetwork

type ErrNoNetwork string

ErrNoNetwork is returned if no network with the specified id exists

func (ErrNoNetwork) Error

func (enn ErrNoNetwork) Error() string

func (ErrNoNetwork) NotFound

func (enn ErrNoNetwork) NotFound()

NotFound denotes the type of this error

type ErrNotImplemented

type ErrNotImplemented struct{}

ErrNotImplemented is returned when a Driver has not implemented an API yet

func (*ErrNotImplemented) Error

func (eni *ErrNotImplemented) Error() string

func (*ErrNotImplemented) NotImplemented

func (eni *ErrNotImplemented) NotImplemented()

NotImplemented denotes the type of this error

type IPAMData

type IPAMData struct {
	AddressSpace string
	Pool         *net.IPNet
	Gateway      *net.IPNet
	AuxAddresses map[string]*net.IPNet
}

IPAMData represents the per-network ip related operational information libnetwork will send to the network driver during CreateNetwork()

func (*IPAMData) IsV6

func (i *IPAMData) IsV6() bool

IsV6 returns wheter this is an IPv6 IPAMData structure

func (*IPAMData) MarshalJSON

func (i *IPAMData) MarshalJSON() ([]byte, error)

MarshalJSON encodes IPAMData into json message

func (*IPAMData) String

func (i *IPAMData) String() string

func (*IPAMData) UnmarshalJSON

func (i *IPAMData) UnmarshalJSON(data []byte) error

UnmarshalJSON decodes a json message into IPAMData

func (*IPAMData) Validate

func (i *IPAMData) Validate() error

Validate checks wheter the IPAMData structure contains congruent data

type InterfaceInfo

type InterfaceInfo interface {
	// SetMacAddress allows the driver to set the mac address to the endpoint interface
	// during the call to CreateEndpoint, if the mac address is not already set.
	SetMacAddress(mac net.HardwareAddr) error

	// SetIPAddress allows the driver to set the ip address to the endpoint interface
	// during the call to CreateEndpoint, if the address is not already set.
	// The API is to be used to assign both the IPv4 and IPv6 address types.
	SetIPAddress(ip *net.IPNet) error

	// MacAddress returns the MAC address.
	MacAddress() net.HardwareAddr

	// Address returns the IPv4 address.
	Address() *net.IPNet

	// AddressIPv6 returns the IPv6 address.
	AddressIPv6() *net.IPNet
}

InterfaceInfo provides a go interface for drivers to retrive network information to interface resources.

type InterfaceNameInfo

type InterfaceNameInfo interface {
	// SetNames method assigns the srcName and dstPrefix for the interface.
	SetNames(srcName, dstPrefix string) error
}

InterfaceNameInfo provides a go interface for the drivers to assign names to interfaces.

type JoinInfo

type JoinInfo interface {
	// InterfaceName returns a InterfaceNameInfo go interface to facilitate
	// setting the names for the interface.
	InterfaceName() InterfaceNameInfo

	// SetGateway sets the default IPv4 gateway when a container joins the endpoint.
	SetGateway(net.IP) error

	// SetGatewayIPv6 sets the default IPv6 gateway when a container joins the endpoint.
	SetGatewayIPv6(net.IP) error

	// AddStaticRoute adds a routes to the sandbox.
	// It may be used in addtion to or instead of a default gateway (as above).
	AddStaticRoute(destination *net.IPNet, routeType int, nextHop net.IP) error

	// DisableGatewayService tells libnetwork not to provide Default GW for the container
	DisableGatewayService()
}

JoinInfo represents a set of resources that the driver has the ability to provide during join time.

type NodeDiscoveryData

type NodeDiscoveryData struct {
	Address string
	Self    bool
}

NodeDiscoveryData represents the structure backing the node discovery data json string
