How to build picadoh/motocker docker image?

Question

How can I build the Dockerfile here?

I git clone it and run docker build .. Then I got the following error:

        No working compiler found, or bogus compiler options passed to
        the compiler from Python's standard "distutils" module.  See
        the error messages above.  Likely, the problem is not related
        to CFFI but generic to the setup.py of any Python package that
        tries to compile C code.  (Hints: on OS/X 10.8, for errors about
        -mno-fused-madd see http://stackoverflow.com/questions/22313407/
        Otherwise, see https://wiki.python.org/moin/CompLangPython or
        the IRC channel #python on irc.freenode.net.)

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-EPS61X/cffi/
The command '/bin/sh -c pip install moto && pip install flask' returned a non-zero code: 1

It looks like I have to install more dependencies inside the Dockerfile to resolve unable to execute 'gcc': No such file or directory error.

But if so, how can the build details on dockerhub be successful?

Do I have to put any files inside /opt/moto in order to build successfully?

Looks like a problem in the Dockerfile, you better get in touch with the author — whites11, Jan 23 '18 at 07:16
I recently made a new image that runs all services in the same container, and allows for some initialization at run time, which should be convenient, you can check it out here: https://github.com/juanformoso/moto_docker — juan, Dec 26 '18 at 18:31

You need to install gcc and other additional lib packages to install moto:

RUN apk add --no-cache --update gcc musl-dev libffi-dev openssl-dev

The final Dockerfile is:

FROM python:2.7-alpine

MAINTAINER Hugo Picado

RUN apk add --no-cache --update gcc musl-dev libffi-dev openssl-dev
RUN pip install moto && pip install flask

VOLUME /opt/moto

ADD start.sh .
RUN chmod +x start.sh

EXPOSE 5000

ENTRYPOINT ./start.sh

Does this mean that the successful result of [docker build details](https://hub.docker.com/r/picadoh/motocker/builds/) do not use the [Dockerfile](https://hub.docker.com/r/picadoh/motocker/~/dockerfile/) to build the image? – Brian Jan 23 '18 at 10:01
It was built 9 months ago. I think that time it wasn't necessary. But now it is needed for sure. – nickgryg Jan 23 '18 at 10:03
It installs the last `moto` version which triggers installation of the other packages which should be compiled. I guess 9 months ago it was fine. Dockerfile should define `moto` version or have additional packages in the box like I described in the answer. – nickgryg Jan 23 '18 at 10:17
