Docker

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                                                                                                                                                                            ------

我尝试过的：

已删除 DockerC:\ProgramData 上的桌面文件夹
重新启动Docker
卸载并重新安装Docker

没有任何效果。任何人有使这项工作的想法吗？

下面是我的Docker文件

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 在同一文件夹中，Dockerfile 与您的略有不同，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"]

Docker - 打开 /var/lib/docker/overlay2/xxx/merged/etc/passwd: 没有那个文件或目录

Docker - open /var/lib/docker/overlay2/xxx/merged/etc/passwd: no such file or directory

docker-compose

docker-machine

docker-build
