![]() Update libnetwork to 1b91bc94094ecfdae41daa465cc0c8df37dfb3dd to bring in a fix for stale HNS endpoints on Windows: When Windows Server 2016 is restarted with the Docker service running, it is possible for endpoints to be deleted from the libnetwork store without being deleted from HNS. This does not occur if the Docker service is stopped cleanly first, or forcibly terminated (since the endpoints still exist in both). This change works around the issue by removing any stale HNS endpoints for a network when creating it. Signed-off-by: Sebastiaan van Stijn <github@gone.nl> |

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.
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))
if err != nil {
log.Fatalf("libnetwork.New: %s", err)
}
// Create a network for containers to join.
// NewNetwork accepts Variadic optional arguments that libnetwork and Drivers can use.
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)
}
// 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("docker.io"))
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 {
log.Fatalf("ep.DriverInfo: %s", err)
}
macAddress, ok := epInfo[netlabel.MacAddress]
if !ok {
log.Fatalf("failed to get mac address from endpoint info")
}
fmt.Printf("Joined endpoint %s (%s) to sandbox %s (%s)\n", ep.Name(), macAddress, sbx.ContainerID(), sbx.Key())
}
Future
