带有 python3、chromedriver、chrome & 的 Docker 镜像硒

问题描述

我的目标是使用由 Selenium 抓取网络.python.org/" rel="noreferrer">Python 来自 docker 容器.

我四处寻找并没有找到安装了以下所有内容的 docker 映像:

• Python 3
• ChromeDriver
• Chrome
• 硒

是否有人可以将我链接到 docker image 与所有这些已安装并一起工作?

也许建立我自己的并没有我想象的那么困难，但到目前为止它已经暗示了我.

任何和所有建议都表示赞赏.

解决方案

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

它已经安装了python:

$ docker run selenium/standalone-chrome python3 --versionPython 3.5.2

说明表明您开始使用它

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

要允许 selenium 通过 python 运行，您似乎需要安装软件包.创建这个 Dockerfile:

来自 selenium/standalone-chrome用户根运行 wget https://bootstrap.pypa.io/get-pip.py运行 python3 get-pip.py运行 python3 -m pip install selenium

然后你可以运行它

docker 构建.-t 硒铬 &&docker run -it selenium-chrome python3

与普通的 python docker 镜像相比，优势在于您不需要安装 chromedriver 本身，因为它来自 selenium/standalone-chrome.p>

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.
