How to run google chrome headless in docker

1,参考：

https://stackoverflow.com/questions/43665276/how-to-run-google-chrome-headless-in-docker

https://hub.docker.com/r/browserless/chrome/dockerfile

2，python 做为调用脚本 ，

# -*- coding: utf-8 -*-
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.support.wait import WebDriverWait  # 用于实例化一个Driver的显式等待
from selenium.webdriver.common.by import By  # 内置定位器策略集
from selenium.webdriver.support import expected_conditions as EC  # 内置预期条件函数，具体API请参考此小节后API链接


chrome_options = Options()
# chrome_options.add_argument("--disable-extensions")
chrome_options.add_argument("--disable-gpu")
# chrome_options.add_argument("--no-sandbox") # linux only
chrome_options.add_argument("--headless")
chrome_options.headless = True # also works
driver = webdriver.Chrome(options=chrome_options)

driver.get(
    'https://www.********.de/angebote/opel-corsa-c-edition-klima-8xbereift-schiebedach-benzin-silber-018d31ca-5af8-4cd5-8b47-9ee198bca593?cldtidx=20&cldtsrc=listPage')
try:
    WebDriverWait(driver, 200, 0.5).until(
        EC.presence_of_all_elements_located((By.CLASS_NAME, 'cldt-contact-form-container')))
    print(driver.find_element_by_css_selector('.cldt-item  .sc-grid-row ').text)
    print(driver.find_element_by_xpath('/html/body/div[1]/main/div[2]/div[3]/div[2]/div[1]/div[3]/span[3]').text)
    print(driver.find_element_by_xpath('/html/body/div[1]/main/div[2]/div[3]/div[2]/div[1]/div[3]/span[1]').text)
finally:
    driver.close()  # close the driver
driver.quit()

3, 在docker 中运行，解决了资源问题。
