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

Question

我正在尝试在 M1 Macbook 上的 Docker 容器内运行基于 .Net Core 的 Azure Function，但到目前为止尚未成功。

最初，我使用 Azure Function Core Tools CLI 通过以下命令创建该函数：func init LocalFunctionsProject --worker-runtime dotnet --docker它创建了以下 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 的机器上运行得很好。与此同时，我给自己买了一台 M1 Macbook，在 Docker 容器内运行 Azure Function 不再起作用。它给了我以下例外：

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

到目前为止我尝试过的

1. --platform=linux/amd64通过添加到 Dockerfile 中第一阶段的 FROM 部分来强制 Docker 使用基于 amd 的基础映像，这会给出以下错误消息：

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

#9 3.441 qemu: uncaught target signal 11 (Segmentation fault) - core dumped

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

2. 更改第二阶段的基本映像给mcr.microsoft.com/azure-functions/dotnet:3.0-arm32v7我带来了以下错误：

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，它可能无法在我的 M1 计算机上运行，​​除非有适用于 arm64 v8 计算机的专用 azure-function/dotnet 映像。如果我完全错误，请提示我正确的方向。

你是对的。不幸的是，您的问题范围不支持 M1 架构。请在 GitHub 上查看此主题并随时点赞。
