Docker生成失败，“服务无法build立：复制失败：没有这样的文件或目录”错误

我创build了一个相当标准的，在Docker中托pipe的asp.net核心应用程序。 这在本地运行，现在我试图使用VSTS来构build和部署到Azure。 构build步骤失败的消息： 

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

以下是VSTS的完整日志输出：

这是我的docker-compose.yml 

 version: '3' services: coredockerapi: image: coredockerapi build: context: ./CoreDockerAPI dockerfile: Dockerfile

谢谢。

请参阅以下步骤将项目部署到Azure：

  1. 创build一个新的构build定义
  2. 添加Docker Compose任务（Docker Compose文件： **/docker-compose.ci.build.yml ;操作： Run a Docker Compose command ;命令： run ci-build ）
  3. 添加复制文件任务（源文件夹： $(System.DefaultWorkingDirectory)/[your project path]/obj/Docker/publish ;目录： ** ;目标文件夹： $(Build.ArtifactStagingDirectory) ）
  4. 添加发布构build工件任务（发布path： $(Build.ArtifactStagingDirectory) ）
  5. 创build一个新的版本definitioin
  6. 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 ）

另一方面，有一个相关的线程可能会使你受益： Docker组成VSTS任务失败者
