Error installing gevent in Docker Alpine Python

Question

I'm trying to install gevent on docker image python:3.8.0a4-alpine3.9 which is running gunicorn.

When building the docker, I always get an error "gcc failed with exit status 1".

I've tried installing several packages but none have worked.

Here is the Dockerfile:

FROM python:3.8.0a4-alpine3.9

RUN echo "@edge-community http://dl-cdn.alpinelinux.org/alpine/edge/community" >> /etc/apk/repositories && \
  apk update && \
  apk add build-base python-dev && \
  apk add py-gevent

RUN pip install gunicorn gevent

command: docker build . -t "test:one"

Last few lines of output:

Here is the Gunicorn command I am running:

gunicorn web.wsgi:application --bind 0.0.0.0:8000  --worker-connections 1000 --workers 6 -k gevent

Do you have any ideas on how to install Gevent with this version of python alpine?

Edit - It installs successfully on the last version of Alpine and python - FROM python:3.7-alpine3.8.

Answer 1

ailpine image need install below libs to build gevent.
RUN apk add --no-cache python3-dev libffi-dev gcc musl-dev make
this docker file may help to test

Answer 2

To me none of the above worked with python:3.8-alpine. Worked this:

RUN apk --update --no-cache add python3-dev libffi-dev gcc musl-dev make libevent-dev build-base
