Issue RaspberryPi 3b+ and docker compose : Installing build dependencies: finished with status 'error'

Viewed 917

I'm working on a rapsberrypi 3b+, with Raspbian Buster Lite (version : February 2020) I installed all dependencies as mentioned in this tutorial https://medium.com/@techiebouncer/install-docker-and-docker-compose-on-raspberry-pi-4-raspbian-buster-c5b78b9a0d08. Everything is up-to-date, however with I create my container there is a issue at step two of the Dockerfile when running this cmd :

RUN apt-get update \
&& apt-get install build-essential -y \
&& pip install poetry

The error message is very long:

It seems that there is an issue with libffi-dev module but it is up-to-date. Or with gcc but I don't know what to install?

When you are building a docker image, every build dependency should be installed into the image, not on the host. If the package is required only for building, but not when running the image, you can uninstall it to reduce the image size:

RUN apt update \
  && apt install build-essential libffi-dev -y \
  && pip install poetry \
  && apt remove build-essential libffi-dev -y

how did you know thanks to the error message that you have to install it in the image and not in the host?

The error message

c/_cffi_backend.c:15:10: fatal error: ffi.h: No such file or directory
       #include <ffi.h>
                ^~~~~~~
      compilation terminated.
      error: command 'gcc' failed with exit status 1

indicates that the ffi.h is not available in the image when RUN pip install poetry is executed - the package that provides it on Debian and derivatives is libffi-dev.
