包含更改容器安装源、pip源、临时使用代理上网，所以集成备用

注意：目前python3.8不能安装pymssql

FROM python:3.7-slim

#alpine安装pandas慢,且不能从whl安装，只能编译安装，所以集成备用：
# docker build -t py37:v1_slim . --network=host

#支持中文 (需先安装了中文包)
#ENV LC_ALL=zh_CN.utf8
#ENV LANG=zh_CN.utf8
#ENV LANGUAGE=zh_CN.utf8

ENV BOTTLE_VER 0.12.18

COPY requirements.txt /data/requirements.txt

#更新Alpine的软件源为国内（清华大学）的站点，因为从默认官源拉取实在太慢了。。。

#set是shell的一个命令，因为shell的执行的过程中，如果有某个出错了，也会继续往下执行，set -ex作用就是，当下面的命令执行出错后，就退出执行，不在继续往下执行。

# This script installs APK and Pip prerequisites on container start, or ONBUILD. Notes:

#   * Reads the -r flag to specify a different file path for /requirements.txt
ENTRYPOINT ["uwsgi","--ini","/uwsgi/uwsgi_m.ini"]

可在此基础上再次修改生成适合特定生产用的uwsgi：

#COPY entrypoint.sh /data/entrypoint.sh
