Question

我在Linux上使用MSSQL在Asp.Bet Core 2应用程序上工作。我想配置CI和CD到Azure。我在Visual Studio Team Services中定义了docker-compose任务，但是我收到了一个错误。

这是我的docker-compose：

我还附上了我的VSTS码头工程师：

你知道我做错了吗？

Answer 1

啊哈，我几天前遇到了同样的问题。您的问题在DockerFile中。例如，让我们看一下我的文件：

FROM microsoft/aspnetcore:2.0
ARG source
WORKDIR /app
EXPOSE 80
COPY  ${source:-obj/Docker/publish} .
ENTRYPOINT [ "dotnet","MyWeb.Api.dll" ]

如果docker找不到您在COPY命令中指定的路径，则会产生错误：

Service 'api' failed to build: COPY failed: stat /var/lib/docker/tmp/docker-builder211771018/obj/Docker/publish: no such file or directory

所以，基本上，你需要做的是修复你的构建版本路径（你需要确保在正确的文件夹中构建后的文件）。

此外，如果执行：

，则会出现问题

docker-compose build

它没有构建解决方案。这就是DockerFile无法找到所需文件夹的原因。如果在docker-compose之前执行以下命令，它将起作用。

dotnet publish ./YourSolution.sln -c Release -o ./obj/Docker/publish

Answer 2

关于错误，原因是没有obj / Docker / publish文件夹或文件。（查看列昂尼德的回答）

docker-compose.ci.build.yml文件用于构建项目，docker-compose.yml文件用于运行项目，因此您需要通过带有Dokcer-compose任务的docker-compose.ci.build.yml文件构建项目，然后使用带有Docker-compose任务的docker-compose.yml文件构建/运行图像。

有一个关于docker-compose.ci.build.yml，docker-compose.yml和Dockerfile的帖子：Asp.net core with linux docker container

更新

请参阅以下步骤将项目部署到Azure：

创建新的构建定义
添加Docker撰写任务（Docker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：$(Build.ArtifactStagingDirectory)）
创建新版本definitioin
添加Azure App Service Deploy任务（包或文件夹：$(System.DefaultWorkingDirectory)/[artifact build definition name]/[artifact name];取消选中Publish using Web Deploy option）
