在 Visual Studio 中使用相同的 docker 文件构建 docker 映像的 Azure Pipeline 失败 [英] Azure Pipeline to build docker images fails using same docker file in Visual Studio

问题描述

我正在尝试创建一个部署管道来将我的映像部署到 Kubernetes 集群.此过程的第一步是基于 docker 文件创建映像.我正在使用的 docker 文件是在我添加 docker 支持时从 Visual Studio 生成的，并在右键单击 docker 图像并选择创建它时成功创建了图像.当我配置 Azure Pipeline 时，创建 docker 映像会在尝试构建实际解决方案时失败.上一步获取了所有源文件，但在使用

I'm trying to create a deployment pipeline to deploy my image to Kubernetes cluster. The first step in this process is to create an image based on the docker file. The docker file I'm using was generated from Visual Studio when I added docker support and successfully creates the image when right clicking on the docker image and selecting to create it. When I configure the Azure Pipeline, the create docker image fails as soon as it tries to build the actual solution. The previous step grabs all the sources files but then fails on the docker image creation with

[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 Visual Studio 生成的 docker 文件，由 azure 管道阶段引用以创建 docker 镜像.

The following is the docker file generated from Visual studio and is referenced by the azure pipeline stage to create the docker image.

 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
 build 

 WORKDIR /src      
 COPY ["DockerTest/DockerTest.csproj", "DockerTest/"]

推荐答案

[error]COPY failed: stat/var/lib/docker/tmp/docker-builder158012929/DockerTest/DockerTest.csproj: 没有那个文件或目录

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

根据这个错误信息，错误发生在你的dockerfile的那一行:COPY ["DockerTest/DockerTest.csproj", "DockerTest/"].

According to this error message, the error occurred on the line of your dockerfile: COPY ["DockerTest/DockerTest.csproj", "DockerTest/"].

首先，请确认您没有使用 .dockerignore 文件来排除此文件:DockerTest/DockerTest.csproj，它必须存在于您运行您的目录中构建自.

First, please confirm that you did not use .dockerignore file to exclude this file: DockerTest/DockerTest.csproj, which must exists in the directory where you run your build from.

如果它没有被 .dockerignore 文件忽略，那么你需要考虑你的 dockerfile 位置级别.

If it does not ignored by .dockerignore file, then you need to consider about your dockerfile location level.

DockerTest.csproj 文件不应放在较低的源文件路径级别.您需要更改上下文的来源，将其移动到更高级别.因此，手动修改您的 dockerfile 为:

DockerTest.csproj file should not put at the lower source file path level. You need to change the source of the context, move it at a higher level. So modify your dockerfile manually as :

COPY ["DockerTest.csproj", "DockerTest/"]
