How to build picadoh/motocker docker image?

[lyenliang]

How can I build the Dockerfile of this repository?
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?

Hello. Thanks for reporting the issue. There was an issue with the base image. I just fixed it and the new version is now available at Docker Hub.
