Problems with tobi312/rpi-nginx image

Hi there,
I have a fleet of pi3 running NGINX with the following image:
https://hub.docker.com/r/tobi312/rpi-nginx

Everything worked as expected for months but this morning I got the following error while compiling a new build with “git push balena master”

Any ideas why it’s picking up the wrong architecture?
Any help would be very appreciated,
many thanks,
enrico

Hi there, would you be able to post your Dockerfile so I can try and reproduce the issue?

Hi there, thanks for looking into it.
Please follow our docker compose:

 version: '2'
volumes: 
    resin-data:
services:
  node:
    build: ./node
    expose:
      - "8080"
      - "631"
    volumes: 
      - 'resin-data:/data'
    privileged: true
    restart: always
    network_mode: host
    environment:
      - UDEV=on
    devices:
      - '/dev:/dev'
  nginx:
    build: ./nginx
    depends_on:
      - node
    ports:
      - "80"
    privileged: true
    restart: always
    network_mode: host
    environment:
      - UDEV=on

Please note that both containers are failing so it must be related to the tobi312/rpi-nginx image specifically.
I also posted the issue on github:

and find a similar closed issue that seems related:

I think the maintainer of tobi312/rpi-nginx on Dockerhub has fixed the issue. Before their fix, I was running some tests with balena push <ipAddress> on a Raspberry Pi with the tobi312/rpi-nginx image, and I was getting errors like "/bin/sleep: cannot execute binary file" – as if /bin/sleep had been compiled for another architecture than ARM. After their fix, that problem went away and I was also able to push a trivial Dockerfile to the balenaCloud builders with success:

FROM tobi312/rpi-nginx
CMD while : ; do echo tobi312/rpi-nginx; sleep 5; done

yep, thanks @pdcastro for testing.
I was able to compile correctly so it looks like it was fixed.
Many thanks
