visual-studio - 无效的标志值构建 : pull access denied for build, 存储库不存在或可能需要 'docker login'

Question

我正在尝试在 azure DevOps 管道中构建一个简单的 docker 控制台项目，但我无法构建该项目。

当我尝试复制代码时，出现此错误:

invalid from flag value build: pull access denied for build, repository does not exist or may require 'docker login': denied: requested access to the resource is denied

这里是完整的 docker 文件:

FROM mcr.microsoft.com/dotnet/core/runtime:2.2-nanoserver-1809 AS base
WORKDIR /app

FROM mcr.microsoft.com/dotnet/core/sdk:2.2-nanoserver-1809 AS build
WORKDIR /src
COPY --from=build "ConsoleApp/ConsoleApp.csproj", "ConsoleApp/" #throws the error here. I added --from=build parameter because it couldn't find the project file.
RUN dotnet restore "ConsoleApp/ConsoleApp.csproj"
COPY . .
WORKDIR "/src/ConsoleApp"
RUN dotnet build "ConsoleApp.csproj" -c Release -o /app/build

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

FROM base AS final 
WORKDIR /app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "ConsoleApp.dll"]

更新:

任务 yml 文件:

steps:
- task: Docker@0
  displayName: 'Build an image'
  inputs:
    containerregistrytype: 'Container Registry'
    dockerRegistryConnection: 'doker hub'

我将复制命令更改为 COPY . .

Answer 1

我遇到了同样的问题，this comment给了我一个答案。看起来这也是你的情况。
问题出在 COPY --from=build指令 - 它引用了 build阶段同时修改 build阶段。

FROM mcr.microsoft.com/dotnet/core/runtime:2.2-nanoserver-1809 AS base
WORKDIR /app

# in "base" stage  
FROM mcr.microsoft.com/dotnet/core/sdk:2.2-nanoserver-1809 AS build
WORKDIR /src

# in "build" stage - below command will fail, it could only reference "base" stage
COPY --from=build "ConsoleApp/ConsoleApp.csproj", "ConsoleApp/" 
...

从 build 开始解决问题阶段，然后在构建 base 时复制您的文件阶段。

FROM mcr.microsoft.com/dotnet/core/sdk:2.2-nanoserver-1809 AS build
WORKDIR /app

# in "build" stage  
FROM mcr.microsoft.com/dotnet/core/runtime:2.2-nanoserver-1809 AS base
WORKDIR /src

# in "base" stage - not you can reference "build" stage
COPY --from=build "/app/ConsoleApp/ConsoleApp.csproj", "ConsoleApp/" 
...
