找不到 Docker dotnet 發布輸出

Question

我正在嘗試使用 dockerfile 成功構建/發布項目。 但是，出於某種原因，它找不到應該創建的輸出文件夾。 從其他帖子來看，我的 docker 文件中的一切看起來都是正確的。

文件

FROM mcr.microsoft.com/dotnet/sdk:5.0 as build
WORKDIR /app
COPY . .

RUN dotnet restore
RUN dotnet publish ./ClassLibrary2.csproj -c Release -o out

# Build runtime image
FROM mcr.microsoft.com/dotnet/aspnet:5.0
WORKDIR /app
COPY --from=build /app/out .
ENTRYPOINT ["dotnet", "ClassLibrary2.dll"]

目錄

Docker 命令（從 docker 文件所在的文件夾運行）：docker build -f Dockerfile-SignedAssembly -t signed-assembly。 輸出：

只需替換COPY --from=build /app/out. 通過COPY --from=build /out. 如下所示

FROM mcr.microsoft.com/dotnet/sdk:5.0 as build
WORKDIR /app
COPY . .

RUN dotnet restore
RUN dotnet publish ./ClassLibrary2.csproj -c Release -o /out

# Build runtime image
FROM mcr.microsoft.com/dotnet/aspnet:5.0
WORKDIR /app
COPY --from=build /out .
ENTRYPOINT ["dotnet", "ClassLibrary2.dll"]
