原作者: [db:作者] 来自: [db:来源] 收藏 邀请

本文整理汇总了Golang中github.com/docker/docker/nat.ParsePortSpecs函数的典型用法代码示例。如果您正苦于以下问题：Golang ParsePortSpecs函数的具体用法？Golang ParsePortSpecs怎么用？Golang ParsePortSpecs使用的例子？那么恭喜您, 这里精选的函数代码示例或许可以为您提供帮助。



在下文中一共展示了ParsePortSpecs函数的15个代码示例，这些例子默认根据受欢迎程度排序。您可以为喜欢或者感觉有用的代码点赞，您的评价将有助于我们的系统推荐出更棒的Golang代码示例。

示例1: expose

// EXPOSE 6667/tcp 7000/tcp
//
// Expose ports for links and port mappings. This all ends up in
// b.Config.ExposedPorts for runconfig.
//
func expose(b *Builder, args []string, attributes map[string]bool, original string) error {
	portsTab := args

	if len(args) == 0 {
		return fmt.Errorf("EXPOSE requires at least one argument")
	}

	if b.Config.ExposedPorts == nil {
		b.Config.ExposedPorts = make(nat.PortSet)
	}

	ports, _, err := nat.ParsePortSpecs(append(portsTab, b.Config.PortSpecs...))
	if err != nil {
		return err
	}

	// instead of using ports directly, we build a list of ports and sort it so
	// the order is consistent. This prevents cache burst where map ordering
	// changes between builds
	portList := make([]string, len(ports))
