Docker image for RPI 4

[nielsfaber]

Hello,

I was trying to install your project, but my docker instance fails with error:

standard_init_linux.go:228: exec user process caused: exec format error

Usually this is due to a docker container being compiled for other platform.
So I suppose that my platform is not supported.
I am using a Raspberry pi 4:

pi@raspberrypi:~ $ uname -a
Linux raspberrypi 5.10.43-v7l+ #1425 SMP Wed Jun 16 18:01:57 BST 2021 armv7l GNU/Linux

I already tried switching to different tag, :latest, :dev-arm32v7, :dev-arm64v8, :dev-armhf all gave the same error.

Can you confirm whether the container should be compatible with the Rpi 4?
If not, would it be possible to add support for it?
If yes, any idea what would be going on in my setup?

Thank you.
