Hi,
I am trying to build a multiple architecture image using Docker build.
> docker build -t chargio/liveview_counter --push --platform linux/arm64 .
I get an error (139) running this

The same works great when using amd64.
I am using the Dockerfile generated by mix release --docker. And I’ve changed the debian version several times to use ‘bullseye’ - the default, ‘buster’, and ‘bookworm’, with the same result.
Do you know if there is some problem with the arm64 version of the image?

Can you show us which exact container you’re using as a base?

I get the same error in the build phase using different docker images (as found here: https://hub.docker.com/r/hexpm/elixir/tags?page=1&name=debian-bookworm)
I’ve basically tried the non-slim version and it gets the same error, and I’ve found some similar errors with people trying to do the opposite (running amd64 containers in arm64 computers). I am using qemu 8.0.3 installed using brew.
The dockerfile:
(the version has rotated between different versions of Debian + slim)
The application runs perfectly in x86_64. You can find the code here:
https://github.com/chargio/container_liveview_counter
And the description of it here:

I scanned your linked blog post and noticed this:
When the image really should begin with
hexpm/elixir-arm64and not withhexpm/elixir.Just a blind shot though, assuming you haven’t tried it.

Tried changing from Docker Desktop to Rancher Desktop with the same result when using QEMU and the Apple Virtualization framework (VZ), experimental.

The blog post is using amd64 as it is being deployed in a cluster in the cloud so it is ok.
Now I am trying to deploy the image in a raspberry pi (the cloud cluster is no longer active), and make the app multi-container, and I need to build the image for arm64 to make it run there. Unfortunately, it is not working. I am trying to understand if the problem is the image itself or qemu, because I no longer have an M1 machine to compile it for arm64.
[Corrected - it was amd64, not arm64]

Not sure I get this, if the
FROMDockerfile clause is not pointing at the right arch how can it be okay?sergio-ocon
My mistake, the blogpost was written first time on an M1, but compiled by a friend and updated on an x86_64 Linux machine, then the second one on an X86_64 Mac as I no longer have the M1. Now I am trying to build the ARM version on the X86_64 machine to run it on K3s on a Raspberry Pi 4B, and it is failing.
I will try to do it tomorrow inside the Raspberry, even if it takes forever, and see if it works as expected.

hi @sergio-ocon can you please add these vars to your setup? Mix deps.get memory explosion when doing cross-platform Docker build - #2 by pdgonzalez872

I feel we’re talking past each other here.
Can you just try replacing this:
with this:
?
This should help you build it on any host, no?

Add
ENV ERL_FLAGS="+JPperf true"to your Dockerfile.
