docker - 如何建立picadoh/motocker docker 形象？

Question

如何构建Dockerfile here？

我git clone并运行docker build .。然后我得到以下错误:

        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

看来我必须在Dockerfile中安装更多依赖项才能解决 unable to execute 'gcc': No such file or directory错误。

但是，如果是这样，如何在dockerhub上成功实现 build details？

为了成功构建，是否需要在 /opt/moto中放入任何文件？

Answer 1

您需要安装gcc和其他附加的lib软件包才能安装moto:

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

最终的 Dockerfile是:

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
