示例1: Allocate
// Allocate a network interface
func Allocate(job *engine.Job) engine.Status {
var (
ip *net.IP
err error
id = job.Args[0]
requestedIP = net.ParseIP(job.Getenv("RequestedIP"))
)
if requestedIP != nil {
ip, err = ipallocator.RequestIP(bridgeNetwork, &requestedIP)
} else {
ip, err = ipallocator.RequestIP(bridgeNetwork, nil)
}
if err != nil {
job.Error(err)
return engine.StatusErr
}
out := engine.Env{}
out.Set("IP", ip.String())
out.Set("Mask", bridgeNetwork.Mask.String())
out.Set("Gateway", bridgeNetwork.IP.String())
out.Set("Bridge", bridgeIface)
size, _ := bridgeNetwork.Mask.Size()
out.SetInt("IPPrefixLen", size)
currentInterfaces[id] = &networkInterface{
IP: *ip,
}
out.WriteTo(job.Stdout)
return engine.StatusOK
}示例2: AllocatePort
// Allocate an external port and map it to the interface
func AllocatePort(job *engine.Job) engine.Status {
var (
err error

network = currentInterfaces[id]
)

ip = net.ParseIP(hostIP)
}
// host ip, proto, and host port
hostPort, err = portallocator.RequestPort(ip, proto, hostPort)
if err != nil {
