Raspberry-pi docker error: standard_init_linux.go:178: exec user process caused "exec format error"

Raspberries use ARM and not x86_64 processors. You can only run images created for that architecture. Try searching for ARM or ARMv7 on docker hub. There is a Debian image for ARM I know of but there must be others as well.

The underlying issue is that the binary format used by ARM is not compatible with x86_64, which is the architecture used by most desktop and server systems.

Add to the beginning of your file:

#!/bin/bash 

It works for me
