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。

最佳答案
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)'
关于docker - 在 Visual Studio 中使用相同的 docker 文件构建 docker 镜像的 Azure Pipeline 失败，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/56386812/
