[英]How to install phantomjs and selenium with docker-compose on linux server?
我正在为我的网络抓取工具使用 selenium 和 phantomjs。 一切都适用于我的测试 Windows 应用程序。 尝试将此代码更新添加到我的主应用程序中,使用 docker-compose 部署,我得到了这个: selenium.common.exceptions.WebDriverException: Message: 'phantomjs' executable needs to be in PATH.
我应该如何解决这个问题? 目前我的 docker-compose.yml 有这个代码:
version: '3.1'
services:
tgbot:
container_name: bot
build:
context: .
command: python app.py
restart: always
environment:
WEBAPP_PORT: 3001
env_file:
- ".env"
# bot start after load db
ports:
- 8443:3001
networks:
- botnet
phantomjs:
image: shufo/phantomjs
command: --webdriver 8901
networks:
botnet:
driver: bridge
还有我的python代码:
from selenium import webdriver
driver = webdriver.PhantomJS()
文件:
FROM python:latest
RUN mkdir /src
WORKDIR /src
COPY requirements.txt /src
RUN pip install -r requirements.txt
COPY . /src
PS我正在使用phantomjs,因为我正在抓取的网页有JS。 不适用于 chrome
您的配置有几个问题:
所以这是如何运行所有内容的完整示例:
myfolder
并将app.py
放在那里,内容如下:from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
driver = webdriver.Remote(command_executor='http://phantomjs:8901/wd/hub/',desired_capabilities=DesiredCapabilities.PHANTOMJS)
myfolder
Dockerfile
放入myfolder
:FROM python:latest
WORKDIR /configs
COPY requirements.txt requirements.txt
RUN pip install -r requirements.txt
docker-compose.yml
放入myfolder
:version: '3.1'
services:
tgbot:
build: .
container_name: bot
volumes:
- .:/apps
command: python /apps/app.py
depends_on:
- phantomjs
networks:
- botnet
phantomjs:
container_name: phantomjs
image: shufo/phantomjs
command: --webdriver 8901
networks:
- botnet
networks:
botnet:
driver: bridge
cd myfloder
, cd myfloder
docker-compose up
输出:
