Question

我正在尝试使用AspNetCore3 Preview6.19307.2开发Web应用程序，并将在我的Azure WebApp上发布。

我不是第一次尝试发布AspNetCore 3的预览版。由于未知的原因，我不能。 WebApp应用程序告诉我无法启动（内部服务器错误）。

在Kudu控制台中，当我尝试使用AspNetCore3 Preview5时，我已经安装了ASP.NET Core 3.0 (x64) Runtime（版本3.0.0-preview5-19227-01）。

现在，从Preview6开始，此版本没有扩展名。

因此，我尝试在Docker上使用该应用程序。

我尝试了多个dockerfile，包括：

由Visual Studio生成：

FROM mcr.microsoft.com/dotnet/core/runtime:3.0-buster-slim-arm64v8 AS base
WORKDIR /app
EXPOSE 80

# Install ASP.NET Core
ENV ASPNETCORE_VERSION 3.0.0-preview6.19307.2

FROM mcr.microsoft.com/dotnet/core/sdk:3.0-buster AS build
WORKDIR /src
COPY ["IdeaStudio.Web.Server/IdeaStudio.Web.Server.csproj", "IdeaStudio.Web.Server/"]
COPY ["IdeaStudio.Web.Client/IdeaStudio.Web.Client.csproj", "IdeaStudio.Web.Client/"]
COPY ["IdeaStudio.Web.Shared/IdeaStudio.Web.Shared.csproj", "IdeaStudio.Web.Shared/"]
RUN dotnet restore "IdeaStudio.Web.Server/IdeaStudio.Web.Server.csproj"
COPY . .
WORKDIR "/src/IdeaStudio.Web.Server"
RUN dotnet build "IdeaStudio.Web.Server.csproj" -c Release -o /app

FROM build AS publish
RUN dotnet publish "IdeaStudio.Web.Server.csproj" -c Release -o /app

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

https://github.com/dotnet/dotnet-docker/blob/master/3.0/sdk/buster/amd64/Dockerfile
https://github.com/dotnet/dotnet-docker/blob/master/3.0/aspnet/buster-slim/amd64/Dockerfile
...此存储库中的几个：https://github.com/dotnet/dotnet-docker/或Visual Studio dockerfile以及在此存储库中找到的其他docker映像的URL。

第一个日志：

在上一次尝试中，我尝试使用VSCode和一个终端： docker build -t ideastudio -f Dockerfile .

我还有另一个错误：

error MSB6003: The specified task executable "node" could not be run. System.ComponentModel.Win32Exception (2): No such file or directory [/src/IdeaStudio.Web.Client/IdeaStudio.Web.Client.csproj]

最初，我的DOCKERFILE被添加到/src/Ideatudio.Web.Server文件夹中。在此消息之前，我的文件树看起来像

- IdeaStudio.Web.Client\ (csproj and files)
- IdeaStudio.Web.Server\ (csproj and files)
    - DOCKERFILE
- IdeaStudio.Web.Shared\...

之后：

- IdeaStudio.Web.Client\ (csproj and files)
- IdeaStudio.Web.Server\ (csproj and files)
- IdeaStudio.Web.Shared\...
- DOCKERFILE

我有同样的错误...

我已还原docker文件（由Visual Studio生成）的原始版本， D:\repos\IdeaStudio.Web\src\IdeaStudio.Web.Server\DOCKERFILE：

Answer 1

您的问题与相对路径有关。对于COPY，第一个值相对于当前dockerfile路径，而第二个参数相对于docker容器中的WORKDIR。

尝试以下dockerfile：

    FROM mcr.microsoft.com/dotnet/core/aspnet:3.0-buster-slim AS base
    WORKDIR /app
    EXPOSE 80

    FROM mcr.microsoft.com/dotnet/core/sdk:3.0-buster AS build
    WORKDIR /src
    COPY ["src/IdeaStudio.Web.Server/IdeaStudio.Web.Server.csproj", "IdeaStudio.Web.Server/"]
    COPY ["src/IdeaStudio.Web.Client/IdeaStudio.Web.Client.csproj", "IdeaStudio.Web.Client/"]
    COPY ["src/IdeaStudio.Web.Shared/IdeaStudio.Web.Shared.csproj", "IdeaStudio.Web.Shared/"]
    RUN dotnet restore "IdeaStudio.Web.Server/IdeaStudio.Web.Server.csproj"
    COPY "src" .
    WORKDIR "/src/IdeaStudio.Web.Server"
    RUN dotnet build "IdeaStudio.Web.Server.csproj" -c Release -o /app

    FROM build AS publish
    RUN dotnet publish "IdeaStudio.Web.Server.csproj" -c Release -o /app

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

将ASP.Net Core 3预览版6发布到Azure
