Support for linux/i386 images on Talos using siderolabs/binfmt-misc extension

[marcopornic]

Hello Talos team,

I am trying to deploy a Docker image based on the linux/i386 architecture (32-bit) on Talos.

I noticed there is an extension called siderolabs/binfmt-misc which may provides multi-format binary support via binfmt_misc.

Would enabling this extension on Talos allow running containers based on linux/i386 images?
Are there any specific limitations or considerations to be aware of in this scenario?

Thank you in advance for your help !

Best regards,
Marc

What is your host architecture?

If it's x86-64, your linux/386 containers should probably run without issues.

I've made a baremetal ISO like this :

mkdir -p _out/
docker run --rm -t \
  -v $PWD/_out:/secureboot:ro \
  -v $PWD/_out:/out \
  -v $PWD/image-cache.oci:/image-cache.oci:ro \
  -v /dev:/dev \
  --privileged \
  ghcr.io/siderolabs/imager:v1.9.5 \
  iso \
  --image-cache /image-cache.oci

And boot in a HyperV VM.

Thanks for your reply and your help.

I confirmed everything works fine deploying my linux/386 image on Talos on an x86-64 host.

The issues I encountered were due to how I managed architecture settings during Zarf packaging and deployment.

So it’s on my side, not Talos :)

Thanks again for your support!
