standard_init_linux.go:211: exec user process caused "exec format error" with 1.7.14 arm64 builds

[EugenMayer]

I am building a wrapper image arround the official traefik release. While the amd64 build works as usual ( and has been working for months, same as the arm builds ) with 1.7.14 the arm build is failing:

docker build -t eugenmayer/traefik:arm64 . -f Dockerfile_arm64

What has been changed from 1.7.13 to 1.7.14 concerning the image itself? i have seen that go has been upgraded, but that should not break the gem installation of a ruby gem i would say.

The same gem installs just find in the amd64 build with 1.7.14

Hi @EugenMayer, would you mind opening a topic in the community forum at for such subject, unless it's confirmed that it's an issue? We want to use issue tracker for tracking confirmed bug and new feature requests.

Btw, I tested your repo on Docker4Mac and it builds without any issues:

docker build -t eugenmayer/traefik:arm64 . -f Dockerfile_arm64

Are you sure the Docker Engine used by your Docker client has the Quem library for ARM supports? It looks like that the shell of the image, when called by the RUN instruction, is throwing the exec error meaning the default ash for ARM/alpine is not able to be executed by the kernel behind your Docker Engine.
