本文整理匯總了Golang中github.com/docker/libnetwork/portallocator.Get函數的典型用法代碼示例。如果您正苦於以下問題：Golang Get函數的具體用法？Golang Get怎麽用？Golang Get使用的例子？那麽, 這裏精選的函數代碼示例或許可以為您提供幫助。
在下文中一共展示了Get函數的4個代碼示例，這些例子默認根據受歡迎程度排序。您可以為喜歡或者感覺有用的代碼點讚，您的評價將有助於係統推薦出更棒的Golang代碼示例。
示例1: allocateDaemonPort
// allocateDaemonPort ensures that there are no containers
// that try to use any port allocated for the docker server.
func allocateDaemonPort(addr string) error {
host, port, err := net.SplitHostPort(addr)
if err != nil {
return err
}
intPort, err := strconv.Atoi(port)
if err != nil {
return err
}
var hostIPs []net.IP
if parsedIP := net.ParseIP(host); parsedIP != nil {
hostIPs = append(hostIPs, parsedIP)
} else if hostIPs, err = net.LookupIP(host); err != nil {
return fmt.Errorf("failed to lookup %s address in host specification", host)
}
pa := portallocator.Get()
for _, hostIP := range hostIPs {
if _, err := pa.RequestPort(hostIP, "tcp", intPort); err != nil {
return fmt.Errorf("failed to allocate daemon listening port %d (err: %v)", intPort, err)
}
}
return nil
}示例2: requestHostPort
// requestHostPort finds a free port on the host
func requestHostPort(proto string) (int, error) {
pa := portallocator.Get()
return pa.RequestPortInRange(nil, proto, 0, 0)
}示例3: New
// New returns a new instance of PortMapper
func New() *PortMapper {
return NewWithPortAllocator(portallocator.Get())
}示例4: New
// New returns a new instance of PortMapper
func New(proxyPath string) *PortMapper {
return NewWithPortAllocator(portallocator.Get(), proxyPath)
}
