Docker - 打开/var/lib/docker/overlay2/xxx/merged/etc/passwd：没有这样的文件或目录

Question

我正在尝试“docker build -t aspnetapp”。 但它停止并在下面显示错误。

=> ERROR [base 2/2] WORKDIR /app                                                                                                                                                                            ------
 > [base 2/2] WORKDIR /app:

我尝试过的：

• 删除了 C:\ProgramData 上的 DockerDesktop 文件夹
• 重启 Docker
• 卸载并重新安装 Docker

没有任何作用。有没有人有想法来完成这项工作？

下面是我的 Dockerfile

FROM mcr.microsoft.com/dotnet/core/aspnet:3.1-nanoserver-1903 AS base
WORKDIR /app
EXPOSE 80
EXPOSE 443

FROM mcr.microsoft.com/dotnet/core/sdk:3.1-nanoserver-1903 AS build
WORKDIR /src
COPY ["SampleCoreProject.csproj", "SampleCoreProject/"]
RUN dotnet restore "SampleCoreProject.csproj"
COPY . .
WORKDIR "/src/SampleCoreProject"
RUN dotnet build "SampleCoreProject.csproj" -c Release -o /app/build

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

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

我创建了一个新项目，.csproj 和 Dockerfile 在同一个文件夹中，Dockerfile 和你的有点不同，试试这个：

FROM mcr.microsoft.com/dotnet/aspnet:3.1 AS base
WORKDIR /app
EXPOSE 80
EXPOSE 443

FROM mcr.microsoft.com/dotnet/sdk:3.1 AS build
WORKDIR /src
COPY ["SampleCoreProject.csproj", "."]
RUN dotnet restore "./SampleCoreProject.csproj"
COPY . .
WORKDIR "/src/."
RUN dotnet build "SampleCoreProject.csproj" -c Release -o /app/build

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

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