windows - Docker构建请求访问被拒绝，存储库不存在或可能需要

Question

我试图在不使用Visual Studio的情况下生成Docker镜像。我在项目文件夹中，并且从Windows 10管理员命令行docker build .执行，我不知道如何进行此工作。

这是我的dockerfile:

#See https://aka.ms/containerfastmode to understand how Visual Studio uses this Dockerfile to build your images for faster debugging.
FROM mcr.microsoft.com/dotnet/core/aspnet:3.1-buster-slim AS base
WORKDIR /app
EXPOSE 80
EXPOSE 443

FROM mcr.microsoft.com/dotnet/core/sdk:3.1-buster AS build
WORKDIR /src
COPY ["src/App.Web/App.Web.csproj", "src/App.Web/"]
RUN dotnet restore "App.Web.csproj"
COPY . .
WORKDIR "/src/App.Web"
RUN dotnet build App.Web.csproj -c Debug -o /app

FROM build as debug
RUN dotnet publish "App.Web.csproj" -c Debug -o /app

FROM base as final
WORKDIR /app
COPY --from=publish/app /app .
ENTRYPOINT ["dotnet","App.Web.dll"]

您有称为基础，构建和调试的阶段。然后，在最后阶段，您将具有:

COPY --from=publish/app /app .

当docker无法找到名称为 publish/app的舞台时，它会尝试查找不存在的图像。我猜你想从构建阶段复制，例如

COPY --from=build /app .
