Docker之搭建Ubuntu+Google-Chrome+Selenium

Selenium是浏览器功能自动化测试工具，在终端界面下也能运行，所以可作为爬虫的 js 引擎。

Dockerfile:

关于  *.deb 的安装，有三种办法

1. dpkg -i [包名] ， 容易出现依赖不存在导致安装失败。因此先试错一次，然后用apt install -f 去修复依赖

dpkg -i [包名]
apt install -f
dpkg -i [包名]

2. gdebi [包名]， 自动安装依赖，但需要先安装 gdebi

apt install gdebi
gdebi [包名] 

3. apt install [包名]， 仅支持 ubuntu16.04 及之后版本， 需要注意的是即使在当前路径包名前依然要加上路径 ./

apt install [包名]
