示例1: allocateVIP

// allocate virtual IP for a single endpoint attachment of the service.
func (na *NetworkAllocator) allocateVIP(vip *api.Endpoint_VirtualIP) error {
	localNet := na.getNetwork(vip.NetworkID)
	if localNet == nil {
		return fmt.Errorf("networkallocator: could not find local network state")
	}

	ipam, _, err := na.resolveIPAM(localNet.nw)
	if err != nil {
		return fmt.Errorf("failed to resolve IPAM while allocating : %v", err)
	}

	for _, poolID := range localNet.pools {
		ip, _, err := ipam.RequestAddress(poolID, nil, nil)
		if err != nil && err != ipamapi.ErrNoAvailableIPs && err != ipamapi.ErrIPOutOfRange {
			return fmt.Errorf("could not allocate VIP from IPAM: %v", err)
		}

		// If we got an address then we are done.
		if err == nil {
			ipStr := ip.String()
			localNet.endpoints[ipStr] = poolID
			vip.Addr = ipStr
			return nil
		}
	}

	return fmt.Errorf("could not find an available IP while allocating VIP")
