exec user process caused "exec format error"

[notslang]

I'm trying to run certbot on a Raspberry Pi 3 B+, but I get the error standard_init_linux.go:211: exec user process caused "exec format error".

[slang@alarmpi ~]$ docker pull certbot/certbot

Running the same 2 commands on my non-ARM laptop works as expected; it prints out the help text.

Ggoogling around, it looks like this error is caused by the image being x86 specific rather than ARM. See issues like https://github.com/docker-library/mysql/issues/228.

I'm honestly not very familiar with this. Is there a way for us to configure our automated builds on Docker Hub to builds for different architectures?

just use: certbot: image: certbot/certbot:arm32v6-latest :-)

I think this issue is resolved with #3.

Seems like the issue is still not resolved

pi@raspberrypi:~/docker $ docker run -it certbot/certbot arbitrary-command
standard_init_linux.go:211: exec user process caused "exec format error"
failed to resize tty, using default size

When I used certbot/certbot:arm32v6-latest it worked fine.

That is expected behavior because we chose not to add a manifest since it is an experimental feature at https://github.com/certbot-docker/certbot-docker/pull/3.

If you would like us to reconsider, please open a new issue/PR.
