docker - 在 Visual Studio 中使用相同的 docker 文件构建 docker 镜像的 Azure Pipeline 失败

Question

我正在尝试创建一个部署管道来将我的镜像部署到 Kubernetes 集群。此过程的第一步是基于 docker 文件创建镜像。我使用的 docker 文件是在添加 docker 支持时从 Visual Studio 生成的，并在右键单击 docker 镜像并选择创建它时成功创建了镜像。当我配置 Azure Pipeline 时，创建 docker 镜像在尝试构建实际解决方案时就会失败。上一步获取所有源文件，但随后使用

创建 docker 镜像失败

[error]COPY failed: stat/var/lib/docker/tmp/docker-builder158012929/DockerTest/DockerTest.csproj:
 no such file or directory

[error]/usr/bin/docker failed with return code: 1

以下是从 Visual Studio 生成的 docker 文件，并由 azure pipeline 阶段引用来创建 docker 镜像。

 FROM mcr.microsoft.com/dotnet/core/runtime:2.2-stretch-slim AS base

 WORKDIR /app   
 FROM mcr.microsoft.com/dotnet/core/sdk:2.2-stretch AS

 WORKDIR /src      
 COPY ["DockerTest/DockerTest.csproj", "DockerTest/"]      
 RUN dotnet restore "DockerTest/DockerTest.csproj"      
 COPY . .      
 WORKDIR "/src/DockerTest"      
 RUN dotnet build "DockerTest.csproj" -c Release -o /app  

 FROM build AS publish      
 RUN dotnet publish "DockerTest.csproj" -c Release -o /app

 FROM base AS final      
 WORKDIR /app      
 COPY --from=publish /app .

Answer 1

我通过使用与 Visual Studio 中相同的 dockerfile 将 buildContext 设置为“$(Build.Repository.LocalPath)”解决了该问题，而无需调整路径:

在 YAML-Konfiguration 中，我添加了以下行:

buildContext: '$(Build.Repository.LocalPath)'
