示例1: networkAllocAddress

// Allocate an address from the network
func networkAllocAddress(nwCfg *mastercfg.CfgNetworkState, reqAddr string) (string, error) {
	var ipAddress string
	var ipAddrValue uint
	var found bool
	var err error

	// alloc address
	if reqAddr == "" {
		ipAddrValue, found = nwCfg.IPAllocMap.NextClear(0)
		if !found {
			log.Errorf("auto allocation failed - address exhaustion in subnet %s/%d",
				nwCfg.SubnetIP, nwCfg.SubnetLen)
			err = core.Errorf("auto allocation failed - address exhaustion in subnet %s/%d",
				nwCfg.SubnetIP, nwCfg.SubnetLen)
			return "", err
		}

		ipAddress, err = netutils.GetSubnetIP(nwCfg.SubnetIP, nwCfg.SubnetLen, 32, ipAddrValue)
		if err != nil {
			log.Errorf("create eps: error acquiring subnet ip. Error: %s", err)
			return "", err
		}

		// Docker, Mesos issue a Alloc Address first, followed by a CreateEndpoint
		// Kubernetes issues a create endpoint directly
		// since networkAllocAddress is called from both AllocAddressHandler and CreateEndpointHandler,
		// we need to make sure that the EpCount is incremented only when we are allocating
		// a new IP. In case of Docker, Mesos CreateEndPoint will already request a IP that
		// allocateAddress had allocated in the earlier call.
		nwCfg.EpAddrCount++

	} else if reqAddr != "" && nwCfg.SubnetIP != "" {
		ipAddrValue, err = netutils.GetIPNumber(nwCfg.SubnetIP, nwCfg.SubnetLen, 32, reqAddr)
		if err != nil {
			log.Errorf("create eps: error getting host id from hostIP %s Subnet %s/%d. Error: %s",
				reqAddr, nwCfg.SubnetIP, nwCfg.SubnetLen, err)
			return "", err
		}

		ipAddress = reqAddr
	}

	// Set the bitmap
	nwCfg.IPAllocMap.Set(ipAddrValue)

	err = nwCfg.Write()
	if err != nil {
		log.Errorf("error writing nw config. Error: %s", err)
		return "", err
