Docker chrome 설치 해보기

회사 코드 개선 중에 selenium이 더이상 PhantomJs를 지원하지 않아 크롬으로 변경 하려 한다.

Chromedriver install

# linux
wget -O /tmp/chromedriver.zip http://chromedriver.storage.googleapis.com/`curl -sS chromedriver.storage.googleapis.com/LATEST_RELEASE`/chromedriver_linux64.zip
unzip chromedriver.zip chromedriver .

# macos (local test)
wget -O /tmp/chromedriver.zip http://chromedriver.storage.googleapis.com/`curl -sS chromedriver.storage.googleapis.com/LATEST_RELEASE`/chromedriver_mac64.zip
unzip chromedriver_mac.zip chromedriver .

Python code

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.chrome.service import Service
from selenium.common.exceptions import NoSuchElementException

DRIVER_PATH = {chromedriver path}

option = webdriver.ChromeOptions()
option.add_argument("--headless")
option.add_argument("--no-sandbox")
option.add_argument("--disable-dev-shm-usage")

service = Service(executable_path=DRIVER_PATH)
driver = webdriver.Chrome(service=service, options=option)

주의사항 error code 127

위 코드의 주의사항은 크롬이 설치되지 않았을 때 발생하는 코드다.

크롬을 쓰는 로컬이라면 괜찮은데 도커 같은 경우는 크롬을 설치해줘야 한다.

selenium4

selenium 4 로 업그레이드 되면서 많은게 바뀌었는데 가령 find_elements_by_id 같은게 바뀌었다.

from selenium.webdriver.common.by import By

이제 이걸 통해 가져와야 한다.
