Docker:复制失败:CreateFile，在奇怪的位置寻找文件

Question

尝试按照找到的教程 here ，但遇到问题。

我从我的项目目录运行以下命令:

docker build -t my.solution .

我得到以下信息:

Sending build context to Docker daemon  111.6kB
Step 1/17 : FROM microsoft/aspnetcore:2.0-nanoserver-1709 AS base
 ---> ccfb41c8f5b5
Step 2/17 : WORKDIR /app
 ---> Using cache
 ---> e29a68e16001
Step 3/17 : EXPOSE 80
 ---> Using cache
 ---> 976388139964
Step 4/17 : FROM microsoft/aspnetcore-build:2.0-nanoserver-1709 AS build

Step 5/17 : WORKDIR /src

Step 6/17 : COPY my.solution.sln ./
COPY failed: CreateFile \\?\C:\ProgramData\Docker\tmp\docker-builder564035917\my.solution.sln: The system cannot find the file specified.

我不知道它为什么要在它正在寻找的位置找到文件。谁能帮我？我需要进行配置设置吗？我的 Docker 文件如下所示:

FROM microsoft/aspnetcore:2.0-nanoserver-1709 AS base
WORKDIR /app
EXPOSE 80

FROM microsoft/aspnetcore-build:2.0-nanoserver-1709 AS build
WORKDIR /src
COPY my.solution.sln ./
COPY my.solution/my.solution.csproj my.solution/
RUN dotnet restore -nowarn:msb3202,nu1503
COPY . .
WORKDIR /src/my.solution
RUN dotnet build -c Release -o /app

FROM build AS publish
RUN dotnet publish -c Release -o /app

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

更新

根据@AlexGera 的回答，我尝试将 docker 文件更改为:

FROM microsoft/aspnetcore:2.0-nanoserver-1709 AS base
WORKDIR /app
EXPOSE 80

FROM microsoft/aspnetcore-build:2.0-nanoserver-1709 AS build
WORKDIR /src
VOLUME C:/tmp
COPY my.solution.sln c:/tmp/
COPY my.solution/my.solution.csproj my.solution/
RUN dotnet restore -nowarn:msb3202,nu1503
COPY . .
WORKDIR /src/my.solution
RUN dotnet build -c Release -o /app

FROM build AS publish
RUN dotnet publish -c Release -o /app

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

但错误信息没有明显变化:

docker build -t my.solution .

Answer 1

在我看来，新解决方案附带的标准 Dockerfile 存在错误:/

我将 Dockerfile 从 PowerShell 移至解决方案文件夹:

mv Dockerfile ../Dockerfile

从那里运行 docker build 命令对我有用...
