Add ARM support by building OCTI with multi-arch

[Dviros]

Hi there,
Having the exact same issue, even when running with the latest default docker.yml config:
standard_init_linux.go:211: exec user process caused "exec format error"

Running on Ubuntu 18.04

Hi @Dviros , do you use x86 or ARM hardware?

[Dviros]

Hey @richard-julien, attempting to run on Nvidia Jetson Nano (which is ARM based...)
Could that be the issue? Are the docker images not optimized for ARM?

[richard-julien]

Hi @Dviros, today the OCTI docker images is only built for x86.
Supporting ARM looks interesting. I change a bit your ticket to make it a feature request.
Interesting link https://www.docker.com/blog/multi-arch-build-and-images-the-simple-way/
Of course if you have some time you can try directly yourself to build OCTI for ARM with buildx.

Thanks a lot for the clarifications. Will take a deeper look into that

Start trying to build for ARM.

First result for building the frontend

#12 431.5 error /opt/opencti-build/opencti-front/node_modules/node-sass: Command failed.
Looks like node-sass are not built for ARM yet. See sass/node-sass#3033

First result for building the API

Compiled with success.

So looks like we need to wait for node-sass or try to remove it from the front stack. We currently used it with react-timeline-range-slider, so maybe not so easy to do :) @SamuelHassine ?

FYI, node-sass is also not compatible with node.js 16: sass/node-sass#3077.
