带有 docker 和 .NET Core 2.0 的 VSTS CI/CD - 复制失败 [英] VSTS CI/CD with docker and .NET Core 2.0 - Copy failed

问题描述

在学习几个 .NET Core 2.0 Visual Studio Team Services 持续集成/持续交付示例时，我在 VSTS 中遇到了复制错误.

While following a couple .NET Core 2.0 Visual Studio Team Services Continuous Integration/Continuous Delivery examples I bumped into a copy error in VSTS.

通过 VS17 添加 docker 支持在本地使用这样的 dockerfile 效果很好.

Adding docker support via VS17 works great locally with a dockerfile like this.

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

通过一个 MVC 应用程序和一个 WebAPI 应用程序，它在本地与 docker-compose 一起工作得很好.

With an MVC app and a WebAPI app it worked well with docker-compose locally.

在添加 VSTS CI 构建过程并运行它时，我不断遇到副本错误.

When adding a VSTS CI build process and running it I kept hitting errors with the copy.

构建 myapp 服务myapp"失败构建:复制失败:GetFileAttributesEx?C:WindowsTEMPdocker-builder91objDockerpublish:系统找不到指定的路径.C:程序FilesDockerdocker-compose.exe 失败并返回代码:1

Building myapp Service 'myapp' failed to build: COPY failed: GetFileAttributesEx ?C:WindowsTEMPdocker-builder91objDockerpublish: The system cannot find the path specified. C:Program FilesDockerdocker-compose.exe failed with return code: 1

推荐答案

我发现的解决方法是 来自本博客.

请注意，他们在 linux docker 机器上遇到了错误

Note that they hit an error on a linux docker machine

复制失败:stat/var/lib/docker/tmp/docker-builder613328056/obj/Docker/publish: 没有那个文件或目录/usr/bin/docker 失败并返回代码:1

COPY failed: stat /var/lib/docker/tmp/docker-builder613328056/obj/Docker/publish: no such file or directory /usr/bin/docker failed with return code: 1

解决方案:

像这样制作一个 Dockerfile.ci

Make a Dockerfile.ci like this

FROM microsoft/aspnetcore-build:2.0 AS build-env
WORKDIR /app

# Copy csproj and restore as distinct layers
COPY *.csproj ./
RUN dotnet restore

# Copy everything else and build
COPY . ./
RUN dotnet publish -c Release -o out

# Build runtime image
FROM microsoft/aspnetcore:2.0
WORKDIR /app
COPY --from=build-env /app/out .
ENTRYPOINT ["dotnet", "SiliconValve.Vsts.DockerDemo.dll"]

它还需要修改 .dockerignore 文件.

It also requires modifying the .dockerignore file.

bin/
obj/
!*.dll
!obj/Docker/publish/*
!obj/Docker/empty/

这允许我继续 CI 过程，但是我认为有一个更容易解决问题的方法.

This allows me to continue the CI process, however I assume there's an easier fix to the problem.
