Arm emulation on apple silicon fails with a QEMU error

cosmosnicolaou · December 18, 2021, 7:04pm

arm (note, not arm64) emulation seems to tickle a bug in QEMU, this is with the latest version of docker desktop:

cat > Dockerfile <<eof
FROM balenalib/rpi-raspbian:bullseye-20210925

USER root

RUN apt-get update -y && apt-get upgrade -y
eof
docker build  .

leads to the following error:

[2/2] RUN apt-get update -y && apt-get upgrade -y:
#6 1.018 Get:1 Index of /debian bullseye InRelease [23.5 kB]
#6 1.018 qemu: uncaught target signal 4 (Illegal instruction) - core dumped

### Issue: I tried to run the 'apache/airflow' image (https://hub.docker.com/r/apache/airflow) with docker-compose. The container is able to start, but after running some airflow commends, the container is terminated with an error 'qemu: uncaught target signal 4 (Illegal instruction) - core dumped' ### Actual behavior Following is my docker-compose.yml file ``` version: '3.8' services: webserver: image: apache/airflow command: bash -c "airflow db init && airflow users create -u admin -f Peter -l Parker -r Admin -e spiderman@superhero.org -p **** && airflow webserver" volumes: - ./dags:/opt/airflow/dags environment: - AIRFLOW__CORE__SQL_ALCHEMY_CONN=mysql+mysqldb://airflow:airflow@192.168.64.1:3306/airflow - AIRFLOW__CORE__EXECUTOR=LocalExecutor ports: - "8080:8080" ``` After I run "docker-compose up", I get: ``` Recreating docker-airflow_webserver_1 ... done Attaching to docker-airflow_webserver_1 webserver_1 | DB_BACKEND=mysql+mysqldb webserver_1 | DB_HOST=192.168.64.1 webserver_1 | DB_PORT=3306 webserver_1 | webserver_1 | DB: mysql+mysqldb://airflow:***@192.168.64.1:3306/airflow webserver_1 | [2021-01-08 04:28:45,451] {db.py:678} INFO - Creating tables webserver_1 | INFO [alembic.runtime.migration] Context impl MySQLImpl. webserver_1 | INFO [alembic.runtime.migration] Will assume non-transactional DDL. webserver_1 | qemu: uncaught target signal 4 (Illegal instruction) - core dumped webserver_1 | /bin/bash: line 1: 21 Illegal instruction airflow db init docker-airflow_webserver_1 exited with code 132 ``` ### Information  - macOS Version: Big Sur - Docker for Mac: Apple silicon preview version released on Dec 16  Do I have to wait for the production version of Docker Desktop for Mac? How can I fix it? Thanks!

They say what you suspected that it is a qemu bug.

There is also a bug report in balenalib github repository:

**Steps to reproduce:** On a Apple Silicon machine: 1. Create a Dockerfile… that contains the following: ``` FROM balenalib/rpi-raspbian RUN apt-get update -y ``` 2. Build it: ```docker build .``` **Expected**: No errors **Actual**: Fails due to ```#5 2.888 W: GPG error: http://archive.raspberrypi.org/debian buster InRelease: Unknown error executing apt-key #5 2.888 E: The repository 'http://archive.raspberrypi.org/debian buster InRelease' is not signed. #5 2.888 W: GPG error: http://archive.raspbian.org/raspbian buster InRelease: Unknown error executing apt-key #5 2.888 E: The repository 'http://archive.raspbian.org/raspbian buster InRelease' is not signed. ------ executor failed running [/bin/sh -c apt-get update -y]: exit code: 100 ``` **Configurations**: `balenalib/raspberry-pi` on Intel WORKS `balenalib/raspberry-pi` on Apple Silicon FAILS `balenalib/raspberrypi3` on Apple Silicon WORKS On Apple Silicon, latest Big Sur and Docker are used: ```% docker -v Docker version 20.10.5, build 55c4c88 % sw_vers ProductName: macOS ProductVersion: 11.2.3 BuildVersion: 20D91 ``` Additional debugging: ``` % docker run -ti --platform linux/arm/v6 balenalib/rpi-raspbian:latest root@627909b18b76:/# apt-get update -y Get:1 http://archive.raspberrypi.org/debian buster InRelease [32.9 kB] Get:2 http://archive.raspbian.org/raspbian buster InRelease [15.0 kB] Err:1 http://archive.raspberrypi.org/debian buster InRelease Unknown error executing apt-key Err:2 http://archive.raspbian.org/raspbian buster InRelease Unknown error executing apt-key Reading package lists...

The error message is different but I suspect the reason is the same. If you try to run the “buster” version you will get the other error message referring to “apt-key”.

At the end of the issue you can find a link to the balena forum:

I don’t know balena so I don’t really understand what they say there but it might help you.
