带有python3，chromedriver，chrome&的Docker映像硒 [英] Docker image with python3, chromedriver, chrome & selenium

问题描述

我的目标是使用 Selenium 抓取网络。 www.python.org/ rel = nofollow noreferrer> Python 来自 docker < a href = https://www.docker.com/resources/what-c​​ontainer rel = nofollow noreferrer>容器。

我ve到处寻找并没有找到安装了以下所有程序的docker映像：

• Python 3


• ChromeDriver


• Chrome


• 硒

有人可以将我链接到 docker image 并安装了所有这些并且可以一起工作吗？

也许构建自己的镜像并不像我认为，但是到目前为止，这已经暗示了我。

任何人和所有建议都值得赞赏。

解决方案

尝试 https://github.com/SeleniumHQ/docker-selenium 。

它已安装python：

  $ docker run selenium / standalone -chrome python3 --version 
 Python 3.5.2 
  

说明指示您以

  docker run -d -p 4444：4444 --shm-size = 2g硒/独立铬
  

编辑：

允许Selenium通过python运行，看来您需要安装软件包。创建以下 Dockerfile ：

  FROM硒/独立铬
 
用户root 
运行wget https://bootstrap.pypa.io/get-pip.py 
运行python3 get-pip.py 
运行python3 -m pip安装硒
  

然后您可以使用

<$ p运行它$ p> docker build。 -t硒铬b
docker run -it selenium-chrome python3


与普通相比的优势 python 泊坞窗映像是，您不需要安装chromedriver本身，因为它来自 selenium / standalone-chrome 。

My objective is to scrape the web with Selenium driven by Python from a docker container.

I've looked around for and not found a docker image with all of the following installed:

• Python 3
• ChromeDriver
• Chrome
• Selenium

Is anyone able to link me to a docker image with all of these installed and working together?

Perhaps building my own isn't as difficult as I think, but it's alluded me thus far.

Any and all advice appreciated.

解决方案

Try https://github.com/SeleniumHQ/docker-selenium.

It has python installed:

$ docker run selenium/standalone-chrome python3 --version
Python 3.5.2

The instructions indicate you start it with

docker run -d -p 4444:4444 --shm-size=2g selenium/standalone-chrome

Edit:

To allow selenium to run through python it appears you need to install the packages. Create this Dockerfile:

FROM selenium/standalone-chrome

USER root
RUN wget https://bootstrap.pypa.io/get-pip.py
RUN python3 get-pip.py
RUN python3 -m pip install selenium

Then you could run it with

docker build . -t selenium-chrome && \
    docker run -it selenium-chrome python3

The advantage compared to the plain python docker image is that you won't need to install the chromedriver itself since it comes from selenium/standalone-chrome.
