Python 3.x 当pip需求中包含雪花依赖项时，docker构建失败

我正在尝试用python应用程序构建docker映像。但是，当我将“雪花连接器python”添加到pip requirements.txt文件时，docker构建失败了

requirements.txt：-

boto3
pycryptodome
snowflake-connector-python

Dockerfile：-

FROM python:alpine3.6
RUN python --version

COPY . /sample-app
WORKDIR /sample-app

RUN python -m pip install --upgrade pip
RUN pip install --upgrade setuptools
RUN pip --version
RUN pip install -r requirements.txt

CMD [ "python", "runner.py" ]

CLI docker生成：-

docker build -t sample-app:1.0 .

错误：-

Step 8/9 : RUN pip install -r requirements.txt

将编译库/包添加到您的alpine映像中，在上面的Dockerfile中添加下面的

RUN

语句，然后在

pip安装之前

WORKDIR /sample-app
RUN apk add --no-cache build-base libffi-dev openssl-dev ncurses-dev
RUN python -m pip install --upgrade pip

这基本上是安装gcc、g++&make来编译包，在您的情况下也需要其他包。我猜它们已经被删除了，或者没有与原始的
python:alpine3.6
image一起提供。
阿尔卑斯linux非常小，它们必须删除所有内容，所以您必须自己安装它。有些pip软件包需要在您的计算机上编译/构建，但alpine缺少这些依赖项，因此请安装它们，然后执行pip安装，然后删除它们，因为不再需要它们，您将减小映像大小

雪花还说您必须安装
libffi-dev
和
openssl-dev

FROM python:alpine3.6

COPY . /sample-app
WORKDIR /sample-app

RUN apk add --update --no-cache --virtual build-deps gcc python3-dev musl-dev libc-dev linux-headers libxslt-dev libxml2-dev \
&& apk add libffi-dev openssl-dev \
&& pip install --upgrade pip setuptools \
&& pip install -r requirements.txt \
&& apk del build-deps

CMD [ "python", "runner.py" ]

我发现，在为AWS lambda构建python部署包时，在linux之上使用会有所帮助，但我不确定这是否有帮助

我需要像Mazel Tov建议的那样
yum-y安装gcc-libffi-devel-openssl-devel
，以获得剩余的资源
