I have installed Docker on a RHEL7 server and it is running. I am trying to build my first Docker Image that I found on GitHub to build a python library docker image for use with Demisto. https://github.com/demisto/tools/tree/master/docker

I modified the requirements folder and just added one python package, impyla. As you can see below it downloads and impyla and its dependencies but then returns an error message, but I am not sure what to do now. Does anybody with docker and or python experience know what I should try next?

    It's failing because of gcc dependency. You have to install it via the dockerfile. python-dev or python3-dev might be the package that you are looking for based on the version of python that you are using Commented Dec 13, 2018 at 0:29

Basically you have to add all the dependencies yourself. Line 2 is what I added I have just modified the Dockerfile and built it myself. It works. Let me know if you have any questions.

FROM python:2.7.15-slim-jessie

RUN apt-get update -y && apt-get install apt-file -y && apt-file update -y && apt-get install -y python3-dev build-essential

COPY requirements.txt .

RUN pip install --no-cache-dir -r requirements.txt

I would definitively add DEBIAN_FRONTEND=noninteractive in front of apt-get install -y python3-dev build-essential

This is for anyone who is using a continuumio/miniconda3:latest based image and encountered the unable to execute 'gcc' error. I added the following line to my Dockerfile, and it is all that I minimally needed:

RUN apt-get update && apt-get -y install gcc

Note that the above image in turn uses debian:latest. Also, I didn't need all of build-essential.

I am going to guess this is the answer most people need when running into this problem.

python3-dev and build-essential should satisfy most build needs including gcc.

FROM python:3.6.13-slim
WORKDIR /app
COPY . .
RUN apt update -y && apt-get install -y python3-dev build-essential && \
    pip install -r requirements.txt

What would be equivalent packages or how to install these packages in the alpine version of python(python3.7:alpine) "python3-dev and build-essential should satisfy most build needs including gcc"
i think this will do the trick "apk add --update alpine-sdk"
