libnetwork - networking for containers

Libnetwork provides a native Go implementation for connecting containers

The goal of libnetwork is to deliver a robust Container Network Model that provides a consistent programming interface and the required network abstractions for applications.

Design

Please refer to the design for more information.

Using libnetwork

There are many networking solutions available to suit a broad range of use-cases. libnetwork uses a driver / plugin model to support all of these solutions while abstracting the complexity of the driver implementations by exposing a simple and consistent Network Model to users.

import (
	"fmt"
	"log"

	"github.com/docker/docker/pkg/reexec"
	"github.com/docker/docker/libnetwork"

	"github.com/docker/docker/libnetwork/options"

func main() {
	if reexec.Init() {
		return
	}

	// Select and configure the network driver
	networkType := "bridge"

	// Create a new controller instance
	driverOptions := options.Generic{}
	genericOption := make(map[string]interface{})
	genericOption[netlabel.GenericData] = driverOptions
	controller, err := libnetwork.New(config.OptionDriverConfig(networkType, genericOption))

	network, err := controller.NewNetwork(networkType, "network1", "")
	if err != nil {
		log.Fatalf("controller.NewNetwork: %s", err)
	}

	// For each new container: allocate IP and interfaces. The returned network
	// settings will be used for container infos (inspect and such), as well as
	// iptables rules for port publishing. This info is contained or accessible
	// from the returned endpoint.
	ep, err := network.CreateEndpoint("Endpoint1")
	if err != nil {
		log.Fatalf("network.CreateEndpoint: %s", err)
	}

		libnetwork.OptionHostname("test"),
		libnetwork.OptionDomainname("example.com"))
	if err != nil {
		log.Fatalf("controller.NewSandbox: %s", err)
	}

	// A sandbox can join the endpoint via the join api.
	err = ep.Join(sbx)
	if err != nil {
		log.Fatalf("ep.Join: %s", err)
	}

	// libnetwork client can check the endpoint's operational data via the Info() API
	epInfo, err := ep.DriverInfo()
	if err != nil {

	}

Overview 

Package libnetwork is a generated protocol buffer package.

It is generated from these files:
	agent.proto

It has these top-level messages:
	EndpointRecord
	PortConfig

Package libnetwork provides the basic functionality and extension points to create network namespaces and allocate interfaces for containers to use. 

networkType := "bridge"

// Create a new controller instance
driverOptions := options.Generic{}
genericOption := make(map[string]interface{})
genericOption[netlabel.GenericData] = driverOptions
controller, err := libnetwork.New(config.OptionDriverConfig(networkType, genericOption))
if err != nil {
	return
}

// Create a network for containers to join.
// NewNetwork accepts Variadic optional arguments that libnetwork and Drivers can make use of
network, err := controller.NewNetwork(networkType, "network1", "")
if err != nil {
	return
}

// For each new container: allocate IP and interfaces. The returned network
// settings will be used for container infos (inspect and such), as well as
// iptables rules for port publishing. This info is contained or accessible
// from the returned endpoint.
ep, err := network.CreateEndpoint("Endpoint1")
if err != nil {
	return
}

// Create the sandbox for the container.
// NewSandbox accepts Variadic optional arguments which libnetwork can use.
sbx, err := controller.NewSandbox("container1",
	libnetwork.OptionHostname("test"),
	libnetwork.OptionDomainname("example.com"))

// A sandbox can join the endpoint via the join api.
err = ep.Join(sbx)
if err != nil {
	return
}

Functions

func NetworkDeleteOptionRemoveLB 

func NetworkDeleteOptionRemoveLB(p *networkDeleteParams)

NetworkDeleteOptionRemoveLB informs a network.Delete() operation that should remove the load balancer endpoint for this network. Note that the Delete() method will automatically remove a load balancing endpoint for most networks when the network is otherwise empty. However, this does not occur for some networks. In particular, networks marked as ingress (which are supposed to be more permanent than other overlay networks) won't automatically remove the LB endpoint on Delete(). This method allows for explicit removal of such networks provided there are no other endpoints present in the network. If the network still has non-LB endpoints present, Delete() will not remove the LB endpoint and will return an error.

func SetExternalKey(shortCtlrID string, containerID string, key string, execRoot string) error
