在 Apple Silicon 上的 Docker 容器中运行基于 .Net Core 的 Azure 函数

问题描述

我正在尝试在 M1 Macbook 上的 Docker 容器内运行基于 .Net Core 的 Azure 函数，但没有成功。

最初我使用 Azure Function Core Tools CLI 通过以下命令创建函数：func init LocalFunctionsproject --worker-runtime dotnet --docker 创建了以下 Dockerfile。

FROM mcr.microsoft.com/dotnet/core/sdk:3.1 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:3.0-appservice
FROM mcr.microsoft.com/azure-functions/dotnet:3.0
ENV AzureWebJobsScriptRoot=/home/site/wwwroot \
    AzureFunctionsJobHost__Logging__Console__IsEnabled=true

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

构建 Docker 镜像并作为容器运行在基于 amd 的机器上工作得很好。与此同时，我给自己买了一台 M1 Macbook，在 Docker 容器中运行 Azure 功能不再有效。它给了我以下异常：

WARNING: The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested

到目前为止我尝试了什么

通过将 --platform=linux/amd64 添加到 Dockerfile 第一阶段的 FROM 部分来强制 Docker 使用基于 amd 的基础映像，这给了我以下错误消息：

> [installer-env 3/3] RUN cd /src/dotnet-function-app &&     mkdir -p /home/site/wwwroot &&     dotnet publish *.csproj --output /home/site/wwwroot:

executor Failed running [/bin/sh -c cd /src/dotnet-function-app &&     mkdir -p /home/site/wwwroot &&     dotnet publish *.csproj --output /home/site/wwwroot]: exit code: 139

将第二阶段的基本图像更改为 mcr.microsoft.com/azure-functions/dotnet:3.0-arm32v7 这给了我以下错误：

WARNING: The requested image's platform (linux/arm) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested
A Fatal error occurred,the folder [/usr/share/dotnet/host/fxr] does not contain any version-numbered child folders

结论

根据我对问题的理解，我个人得出的结论是，除非有用于 arm64 v8 机器的专用 azure-function/dotnet 映像，否则它可能无法在我的 M1 机器上运行。如果我完全错了，请提示我正确的方向。
