Linux容器上Azure函数的Docker问题-函数丢失导致函数运行时为404

Question

这个问题是这个问题的延续：Azure function HTTP triggered on linux container - function not working 404

前一个更多的是要找出什么是根本原因。而MS支持人员向我指出，什么可能是根本原因(但这一点仍有待证实)；

首先，这里是我的文件夹结构(这很重要，因为网络上的大多数示例都假定了项目文件夹中的dockerfile。这是不可能的，一旦你有一个参考库建立)

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

我的初始停靠文件(由MS工具创建，Add->Docker支持)是：

#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

在得到支持人员的回复后(我需要把它放在/home/site/wwwroot中)，最好是使用：

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

我想出了我现在的码头文件：

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

模板文件，我从该文件中创建了以下内容：

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"]

我必须包含引用的项目，并更改图片以适应Azure函数3版本(此模板显然用于版本2)，我还添加了还原包步骤。

但是它不起作用了(和上一次一样)，我现在有点沮丧:我正在上网，我看到了几十个码头文件，据称这些文件是他们的作者发布蓝色功能的工具。

例如，在这个SOF：Azure function HTTP Request 404 when published to Azure through Docker and Visual Studio中

在接受的答复中，dockerfile是：

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

在本例中-显然它位于/app文件夹(而不是在/home/site/wwwroot中)-wtf:d

这张票的作者贴出了一篇文章，这的确对他有好处--与上面的完全不同：

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

发布到/app :)

在一些博客上：https://spin.atomicobject.com/2020/01/09/azure-functions-docker-container/的版本是：

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

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

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

COPY . /home/site/wwwroot

没有任何建筑，修复nuget包裹。

老实说，我的脑子完全搞砸了:)我明白，有时有不止一种方法可以达到相同的方式，但很明显，AzureWebJobsScriptRoot不可能同时成为/home/site/wwwroot和/app :)而且这两个版本似乎都适用于不同的人:)

Answer 1

对于任何有同样问题的人:最后一个码头是：

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

FROM mcr.microsoft.com/dotnet/core/sdk:3.0-buster AS build
WORKDIR /src
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 /home/site/wwwroot
COPY --from=publish /app/publish .
ENV AzureWebJobsScriptRoot=/home/site/wwwroot

对我来说，问题(可能是根本原因)是函数应用程序的应用程序设置之一。

WEBSITE_RUN_FROM_PACKAGE

正因为如此，这是行不通的。一旦我删除了这个应用程序设置-它正确地工作:)

我希望这能节省我找到这个的时间。我只想说，我没有创建这个设置(我不知道它是如何“来”的)

我非常感谢Azure支持团队帮助我找到这个问题；)

Answer 2

因为容器与Azure、DevOps管道和/或terraform脚本有关。发布管道任务对于运行时有一个下拉列表，其中只有".NET“和"JavaScript”选项。".NET“的结果是2.0映像(即使使用v3函数，也已经在2021年)。

​

​

但是下拉列表实际上是一个组合框，您可以在这里输入纯文本。如果您选择使用docker，则可以提供如下格式：

DOCKER|mcr.microsoft.com/azure-functions/dotnet:3.0

这样就可以覆盖默认行为。根据其他答案，您可以创建自己的映像并部署到，而不是从那里提取映像(使用DevOps服务主体已在ACR上读取)，并根据自己的映像创建函数。

设置重写site_config字段"linux_fx_version“。如果您不使用DevOps发布管道，而是使用terraform创建函数应用程序并与其他任务一起部署，那么这将是脚本中的设置(这不是一个完整的运行示例，它只是说明了设置部分)：

resource "azurerm_function_app" "app" {
  name                       = local.function_app_name
