FROM xxxx

COPY sources.list /etc/apt/sources.list

RUN rm -rf /var/lib/apt/lists/* /var/cache/apt/archives/* && apt update -y && \
	apt -d install -y --no-install-recommends build-essential python3.7 python3.7-dev python3-distutils libmysqlclient-dev libyaml-dev libffi-dev libssl-dev libbz2-dev liblz4-dev zlib1g-dev && \

apt

不安装缓存到/var/cache/apt/archives/*.deb ，同时要减少来避免安装非必须的文件，从而减小包体积

  • -d 仅下载 - 不安装或解压归档文件
  • -y 对所有的询问选是
  • --no-install-recommends 来避免安装非必须的文件

pip

只下载不安装放到指定目录

  • download 只下载不安装
  • -i 指定源
  • -d 缓存目录
  • -r 依赖版本文件

安装

apt install

# 安装时不安装顺序会缺依赖，所以装两次
dpkg -i ${DEB_DIR}/*.deb || dpkg -i ${DEB_DIR}/*.deb

pip install virtualenv

# 装virtualenv包
pip install --no-cache-dir --no-index --find-links=${WHL_DIR} virtualenv
virtualenv -p python3.7 --no-site-packages --never-download ${LICENSE_VENV}

# 安装依赖
source ${LICENSE_VENV}/bin/activate
pip install --no-cache-dir --no-index --find-links=${WHL_DIR} -r requirements.txt
deactivate

  • --no-cache-dir 禁用缓存 (docker时候有效减少image体积) 发出任何HTTP请求时，pip首先会检查其本地缓存，以确定是否为该请求存储了合适的响应且尚未过期。如果是这样，则仅返回该响应，而不发出请求

  • --no-index --find-links 不从远程访问 , 使用本地目录

  • --no-site-packages 将不包括已经全局安装的软件包 default version>=1.7
  • --never-download 避免连网 default version>=1.10

还是docker方便
