Docker-open/var/lib/doker/overlay2/xxx/merged/etc/passwd:没有这

Question

我正在尝试‘docker build-t aspnetapp。’但它停止了，并在下面显示了错误。

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

我尝试过的：

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

什么都不管用。有人想让它发挥作用吗？

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，其中.csproj和Dockerfile位于同一文件夹，而Dockerfile与您的有点不同，请尝试以下操作：

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"]
