standard_init_linux.go:178: exec user process caused "exec format error"

docker started throwing this error:

standard_init_linux.go:178: exec user process caused "exec format error"

whenever I run a specific docker container with CMD or ENTRYPOINT, with no regard to any changes to the file other then removing CMD or ENTRYPOINT. here is the docker file I have been working with which worked perfectly until about an hour ago:

RUN chmod +x /bin/start.sh

EXPOSE 8000

ENTRYPOINT ["start.sh", "uwsgi", "--ini", "wsgi.ini"]

I forgot to put

#!/bin/bash

at the top of the sh file, problem solved.

This can happen if you're trying to run an x86 built image on an arm64/aarch64 machine.

You'll need to rebuild the image using the corresponding architecture

Add this code

   #!/usr/bin/env bash

at the top of your script file.

Got the same Error, i was building ARM image after changing to AMD. Issue Fixed

That error usually means you're trying to run this amd64 image on a non-amd64 host (such as 32-bit or ARM).

TRY BUILDING by using buildx and specifying --platfom linux/amd64

Sample Command

docker buildx  build -t ranjithkumarmv/node-12.13.0-awscli . --platform linux/amd64

Another possible reason for this could be if the file is saved with Windows line endings (CRLF). Save it with Unix line endings (LF) and the file will be found.
