azure - 尝试在 azure devops CICD 中构建镜像时出现 docker 错误

Question

无法在 CICD 中构建 docker 镜像，找不到镜像的路径。

这是我的 dockerfile

FROM mcr.microsoft.com/dotnet/framework/aspnet:4.7.2-windowsservercore-ltsc2019

ARG source

WORKDIR /inetpub/wwwroot

COPY ${source:-./obj/Docker/publish} .

#I am choising Azure pipeline agent windows-2019

Step 4/4 : COPY ${source:-./obj/Docker/publish} .

COPY failed: CreateFile \?\C:\ProgramData\docker\tmp\docker-builder174212468\obj\Docker\publish: The system cannot find the path specified. [error]C:\Program Files\Docker\docker.exe failed with return code: 1

Answer 1

我也遇到了同样的问题，最后解决了。我正在将新的 YAML 管道与“Docker@2”任务一起使用。解决方案是指定“buildContext”属性。我必须与您的 Dockerfile 中的workingDir 相同。

Dockerfile:

WORKDIR /src

Azure Pipeline Yaml:

buildContext: 'src/'

完整任务:

- task: Docker@2
  displayName: Build and push an image to container registry
  inputs:
    containerRegistry: '$(dockerRegistryServiceConnection)'
    repository: '$(imageRepository)'
    command: 'buildAndPush'
    Dockerfile: 'src/Dockerfile'
    buildContext: 'src/'
    tags: '$(tag)'
