"Function not implemented" error on Mac M1, works on Ubuntu

Hey team,

I’m currently stuck in the “Function not implemented” error which blocks me from using my Mac. How to reproduce:

1. Follow https://docs.microsoft.com/en-us/azure/azure-functions/functions-run-local to create a nodejs function, add "start": "func start" into package.json
2. Create a Dockerfile to use ubuntu:bionic image and install depedencies

FROM --platform=linux/amd64 ubuntu:bionic

RUN apt update && \
  apt install -y \
  apt-transport-https \
  curl \
  lsb-release gnupg \
  virtualenv && \
  curl -sL https://packages.microsoft.com/keys/microsoft.asc | \
  gpg --dearmor > /etc/apt/trusted.gpg.d/microsoft.asc.gpg && \
  curl -s https://deb.nodesource.com/gpgkey/nodesource.gpg.key | \
  apt-key add && \
  echo \
  "deb [arch=amd64] https://packages.microsoft.com/repos/azure-cli/ $(lsb_release -cs) main" \
  > /etc/apt/sources.list.d/azure-cli.list && \
  echo \
  "deb [arch=amd64] https://packages.microsoft.com/repos/microsoft-ubuntu-$(lsb_release -cs)-prod $(lsb_release -cs) main" \
  > /etc/apt/sources.list.d/dotnetdev.list && \
  echo "deb https://deb.nodesource.com/node_10.x disco main" \
  > /etc/apt/sources.list.d/nodesource.list && \
  apt update && \
  apt install -y \
  azure-cli \
  azure-functions-core-tools \
  libicu-dev \
  build-essential \
  nodejs \
  unzip \
  zip && \
  useradd -m azure && \
  chown -R azure:azure /home/azure/.bashrc && \
  mkdir -p /root/.azure-functions-core-tools/Functions/ExtensionBundles && \
  cd /root/.azure-functions-core-tools/Functions/ExtensionBundles && \
  curl -O https://functionscdn.azureedge.net/public/ExtensionBundles/Microsoft.Azure.Functions.ExtensionBundle/2.4.0/Microsoft.Azure.Functions.ExtensionBundle.2.4.0.zip && \
  mkdir -p Microsoft.Azure.Functions.ExtensionBundle/2.4.0 && \
  unzip Microsoft.Azure.Functions.ExtensionBundle.2.4.0.zip -d Microsoft.Azure.Functions.ExtensionBundle/2.4.0 && \
  cd -

USER azure

1. Create a docker-compose.yaml file

version: "3.7"

services:
  demo:
    container_name: demo
    build:
      context: .
      dockerfile: ./Dockerfile
    user: root
    working_dir: /work
    ports:
      - "7071:7071"
    volumes:
      - ./MyFunctionProj:/work
    command: sh -c "ls -lrt && npm start -- -p 7071 --cors-credentials --cors 'http://localhost:7070'"

networks:
  default:
    driver: bridge
    driver_opts:
      com.docker.network.driver.mtu: 1400

1. Start the docker in Ubuntu environment and Mac M1 environment

Thank you.

I was facing the same issue on my Mac M1. I have managed to resolve it by doing the following

• update docker to 4.16.2
• enable “Use rosetta for x86/amd64 … " option in settings > Features in development”
• set platform to “linux/amd64” when running docker build

You can follow detailed steps and explanation here http://issamben.com/running-azure-function-as-docker-container-on-an-m1-m2/

@anthonychu @stefanushinardi Can you please provide an update for ETA on developing Azure Functions on an M1 chip in docker? Is this a Docker issue or an Azure Functions issue?
