问题描述

此问题是该问题的延续:

This question is a continuation of this one: Azure function HTTP triggered on linux container - function not working 404

上一个更多的是找出根本原因. MS支持人员向我指出，这可能是根本原因(但这仍有待确认；))

The previous one was more about finding out what is the root cause. And MS support guy pointed me, what could be the root cause (but this yet remains to be confirmed;) )

首先，这是我的文件夹结构(这很重要，因为网络上的大多数示例都将dockerfile放在项目文件夹中.一旦要构建引用的库，就不可能拥有它)

Firstly, here is my folder structure (this is important because most of the examples on the net assumes dockerfile in the project folder. And this is impossible to have once you have a referenced library to build)

Solution (root folder of project)
    [Project] BuildChat <-- Referenced project by MyFunctionFolder
    [Project] MyFunctionFolder
        MyFunctionFolder.csproj
        MyFunctionFolderFunc.cs <-- Inside this file there is method run with [FunctionName("MyFunctionFolderFunc")]
        [All Files] RestOfAzureFunctionFiles
    [File] MyFunctionFolderDocker

我最初的docker文件(由MS工具创建，Add-> Docker支持)为:

My initial docker file (created by MS tool, Add->Docker support) was:

#See https://aka.ms/containerfastmode to understand how Visual Studio uses this Dockerfile to build your images for faster debugging.

FROM mcr.microsoft.com/azure-functions/dotnet:3.0 AS base
WORKDIR /app
EXPOSE 80

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

FROM build AS publish
RUN dotnet publish "MyFunctionFolder.csproj" -c Release -o /app/publish

FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
ENV AzureWebJobsScriptRoot=/app

在获得支持女士的答复后(我需要将其保存在/home/site/wwwroot中)，最好的方法是使用:

After response from Ms support staff (that i need to have it in /home/site/wwwroot) and the best would be to use:

func init LocalFunctionsProject --worker-runtime dotnet --docker

我确实提出了我当前的docker文件:

i did came up with my current docker file:

FROM mcr.microsoft.com/azure-functions/dotnet:3.0 AS base
WORKDIR /app
EXPOSE 80

FROM mcr.microsoft.com/dotnet/core/sdk:3.1 AS build
WORKDIR /src
COPY ["BuildChat/BuildChat.csproj", "BuildChat/"]
COPY ["MyFunctionFolder/MyFunctionFolder.csproj", "MyFunctionFolder/"]
RUN dotnet restore "MyFunctionFolder/MyFunctionFolder.csproj"
COPY . .
WORKDIR "/src/MyFunctionFolder"
RUN dotnet build "MyFunctionFolder.csproj" -c Release -o /app/build

FROM build AS publish
RUN dotnet publish "MyFunctionFolder.csproj" -c Release -o /app/publish

FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
ENV AzureWebJobsScriptRoot=/app

我从中创建的模板文件是:

The template file, from which i created that is:

FROM microsoft/dotnet:2.2-sdk AS installer-env

COPY . /src/dotnet-function-app
RUN cd /src/dotnet-function-app && \
    mkdir -p /home/site/wwwroot && \
    dotnet publish *.csproj --output /home/site/wwwroot

# To enable ssh & remote debugging on app service change the base image to the one below
# FROM mcr.microsoft.com/azure-functions/dotnet:2.0-appservice 
FROM mcr.microsoft.com/azure-functions/dotnet:2.0
ENV AzureWebJobsScriptRoot=/home/site/wwwroot \
    AzureFunctionsJobHost__Logging__Console__IsEnabled=true

COPY --from=installer-env ["/home/site/wwwroot", "/home/site/wwwroot"]

我必须包括引用的项目，并更改图像以适合Azure函数3版本(此模板显然适用于版本2)，我也确实添加了还原包步骤.

I have to include the referenced project and to change the images to fit Azure function 3 version (this template is clearly for version 2) I did also add the restore package step.

但是它不起作用(如前一个那样)，我现在有点沮丧:DI正在寻找互联网，我看到了数十个docker文件，据称这些文件可用于其作者发布azure功能.

But it is not working (as the previous one) And I am a little bit frustrated right now :D I am looking the internet and I see dozens of docker files, which allegedly works for their authors to publish azure function.

例如在此SOF中:在接受的答案中，dockerfile是:

in accepted answer the dockerfile was:

FROM mcr.microsoft.com/dotnet/core/sdk:3.1 AS build-env
WORKDIR /app

COPY . ./
RUN dotnet publish myfunction -c Release -o myfunction /out

FROM mcr.microsoft.com/azure-functions/dotnet:3.0 AS base
WORKDIR /app
EXPOSE 80

COPY --from=build-env /app/ao-backendfunctions/out .

ENV AzureWebJobsScriptRoot=/app
ENV AzureFunctionsJobHost__Logging__Console__IsEnabled=true

在此示例中-显然它在/app文件夹中(不在/home/site/wwwroot中)-wtf?:D

In this example - clearly it is in /app folder (not in /home/site/wwwroot) - wtf?:D

此票证的作者发布了一个对他有用的答案-与上面的完全不同:

The author of this ticket posted an anwser, that did work for him - completely different from the above:

FROM mcr.microsoft.com/azure-functions/dotnet:2.0 AS base
WORKDIR /app
EXPOSE 80

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

FROM build AS publish
RUN dotnet publish "FunctionTestAppLinux.csproj" -c Release -o /app/publish

FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
ENV AzureWebJobsScriptRoot=/app

仍然-发布到/app:)

在某些博客上: https://spin. atomicobject.com/2020/01/09/azure-functions-docker-container/ 版本是:

On some blog: https://spin.atomicobject.com/2020/01/09/azure-functions-docker-container/ the version is:

FROM microsoft/azure-functions-dotnet-core2.0:2.0
ENV AzureWebJobsScriptRoot=/home/site/wwwroot
COPY ./bin/Release/netstandard2.0 /home/site/wwwroot

在另一个博客上( https://blog. gutek.pl/2018/03/12/azure-functions-w-docker/)的工作版本为:

On another blog (https://blog.gutek.pl/2018/03/12/azure-functions-w-docker/) working version is:

FROM microsoft/azure-functions-runtime:2.0.0-jessie
ENV AzureWebJobsScriptRoot=/home/site/wwwroot

COPY . /home/site/wwwroot

在没有任何建筑物的情况下，还原nuget软件包.

Without any building, restoring nuget packages.

说实话，我完全不高兴:)我知道，有时候有多种方法可以实现相同的功能，但是显然AzureWebJobsScriptRoot不能同时是/home/site/wwwroot和/app :)而且这两个版本似乎都适用于各种人群:)

To be honest, I am totally brain fucked :) I understand, that sometimes there is more than one way to the same way, but clearly AzureWebJobsScriptRoot cannot be /home/site/wwwroot and /app at the same time :) And both version seems to be working for various people :)

以下是我容器构建中来自Azure门户的日志:

对我来说，问题(可能是根本原因)是功能应用程序的应用程序设置之一

For me also, the issue (probably the root cause) was with one of the Application Settings of the Function App

WEBSITE_RUN_FROM_PACKAGE

因此，它不起作用.一旦我删除了此应用程序设置-即可正常运行:)

Because of that, it was not working. Once I removed this app setting - it worked correctly :)

我希望它将为某人节省我找到它所需的时间.我只会补充说，我没有创建此设置(我不知道它是如何出现"的)

I hope it will save someone the time I needed to find this. I will only add, that i did not create this setting (i don't know how it "came")

我必须非常感谢Azure支持团队帮助我发现问题；)

I have to give big thanks to Azure Support Team with helping me to find the issue;)
