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/daemon/graphdriver.Driver的典型用法代码示例。如果您正苦于以下问题:Golang Driver类的具体用法?Golang Driver怎么用?Golang Driver使用的例子?那么恭喜您, 这里精选的类代码示例或许可以为您提供帮助。



在下文中一共展示了Driver类的18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: checkManyFiles

func checkManyFiles(drv graphdriver.Driver, layer string, count int, seed int64) error {
	root, err := drv.Get(layer, "")
	if err != nil {
		return err
	}
	defer drv.Put(layer)

	for i := 0; i < count; i += 100 {
		dir := path.Join(root, fmt.Sprintf("directory-%d", i))
		for j := 0; i+j < count && j < 100; j++ {
			file := path.Join(dir, fmt.Sprintf("file-%d", i+j))
			fileContent, err := ioutil.ReadFile(file)
