Raspberry pi: standard_init_linux.go:190: exec user process caused "exec format error"

What do I need to do to get the python3.6 container running on a Raspberrypi 3?

> docker run -it tiangolo/uwsgi-nginx-flask:python3.6 bash -il
standard_init_linux.go:190: exec user process caused "exec format error"

Thanks for the help! That solves it!

Just for posterity, these are the commands I ran from start to finish for a working build

# Clone and build image that has rpi support

git clone https://github.com/tiangolo/uwsgi-nginx-docker.git
cd uwsgi-nginx-docker/python3.6
docker build -t tiangolo/uwsgi-nginx:python3.6 .

cd ../../

# Clone and build image that is customized for Flask (uses the previous image as the base)

git clone https://github.com/tiangolo/uwsgi-nginx-flask-docker.git
cd uwsgi-nginx-flask-docker/python3.6
docker build -t tiangolo/uwsgi-nginx-flask:python3.6 .

# Run the image 
docker run -it tiangolo/uwsgi-nginx-flask:python3.6 bash

Raspberry Pi requires images to be compiled for that architecture, ARM. And although Docker now supports different architectures, and I understand the image format also supports specifying architectures, there’s no way to handle it through Docker Hub with the “standard” Docker Hub automated build.

I have already taken several steps (actually some months ago) to make the image, configuration and dependencies compatible with multi-arch (I’ve worked a lot with Pis). The only step missing is Docker Hub support for automated building images for Raspberry Pi.

For now, I suggest you try cloning this repository in your Pi and building the base image locally. In theory, it should all work. After that, you can run your image normally:

git clone https://github.com/tiangolo/uwsgi-nginx-flask-docker.git
cd uwsgi-nginx-flask-docker/python3.6
docker build -t tiangolo/uwsgi-nginx-flask:python3.6 .

And then run again:

docker run -it tiangolo/uwsgi-nginx-flask:python3.6 bash

I’m not running all those commands right now as I’m typing them here, so it’s possible that y put a typo there (so, copy-pasting might not work). Please make sure they are right locally.

And let me know how it goes.
