Docker构建失败，“服务无法构建：复制失败：没有这样的文件或目录”错误

问题描述：

我创建了一个相当标准的asp.net核心应用程序，我在Docker内托管。这在本地运行，现在我试图使用VSTS构建和部署到Azure。构建步骤未能与消息：Docker构建失败，“服务无法构建：复制失败：没有这样的文件或目录”错误

Service 'coredockerapi' failed to build: COPY failed: stat /var/lib/docker/tmp/docker-builder145772260/obj/Docker/publish: no such file or directory

这里是我的搬运工，compose.yml

version: '3' 

services: 
    coredockerapi: 
    image: coredockerapi 
    build: 
     context: ./CoreDockerAPI 
     dockerfile: Dockerfile

谢谢。

我有类似的错误...三重检查你的上/下情况作为Linux区分大小写 –

好吧，文件不存在，他们应该在哪里。 – 4c74356b41

乍一看，'COPY $ {source：-obj/Docker/publish}。'这行看起来很时髦，不应该像'COPY $ {source}/obj/Docker/publish .'这样的东西。我可能是错的，但我从来没有见过类似的东西，并且在网上找不到任何表明这是正确语法的东西。 – DivXZero

请按以下步骤项目部署到Azure中：

创建一个新的构建定义
添加泊坞撰写任务（码头工人撰写文件：**/docker-compose.ci.build.yml;操作：Run a Docker Compose command;命令：run ci-build）
添加复制文件任务（源文件夹：$(System.DefaultWorkingDirectory)/[your project path]/obj/Docker/publish;内容：**;目标文件夹：$(Build.ArtifactStagingDirectory)）
添加发布构建工件任务（发布路径：$(Build.ArtifactStagingDirectory)）
创建新版本definitioin
添加Azure应用服务部署任务（包或文件夹：$(System.DefaultWorkingDirectory)/[artifact build definition name]/[artifact name];取消选中Publish using Web Deploy option）

在另一方面，有可能你受益相关主题：Docker compose VSTS task failder

如果有人运行撰写构建或向上时仍然有问题 - 错误信息：

服务 'PHP' 未能建立：复制失败：统计的/ var/lib中/泊坞窗的/ tmp /泊坞窗建设者...

问题在我的身边是因为在.dockerignore要复制的文件夹被引用。只需删除需要复制的文件夹行。
