I've looked at and tried nearly every other post on this topic with no luck.
EC2
I'm using python 3.6 so I'm using the following AMI amzn-ami-hvm-2018.03.0.20181129-x86_64-gp2 (see here). Once I SSH into my EC2, I download Chrome with:
sudo curl https://intoli.com/install-google-chrome.sh | bash
cp -r /opt/google/chrome/ /home/ec2-user/
google-chrome-stable --version
# Google Chrome 86.0.4240.198
And download and unzip the matching Chromedriver:
sudo wget https://chromedriver.storage.googleapis.com/86.0.4240.22/chromedriver_linux64.zip
sudo unzip chromedriver_linux64.zip
I install python36 and selenium with:
sudo yum install python36 -y
sudo /usr/bin/pip-3.6 install selenium
Then run the script:
import os
import selenium
from selenium import webdriver
CURR_PATH = os.getcwd()
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--headless')
chrome_options.add_argument('--window-size=1280x1696')
chrome_options.add_argument('--disable-gpu')
chrome_options.add_argument('--disable-dev-shm-usage')
chrome_options.add_argument('--hide-scrollbars')
chrome_options.add_argument('--enable-logging')
chrome_options.add_argument('--log-level=0')
chrome_options.add_argument('--v=99')
chrome_options.add_argument('--single-process')
chrome_options.add_argument('--ignore-certificate-errors')
chrome_options.add_argument('--remote-debugging-port=9222')
chrome_options.binary_location = f"{CURR_PATH}/chrome/google-chrome"
driver = webdriver.Chrome(
executable_path = f"{CURR_PATH}/chromedriver",
chrome_options=chrome_options
)
driver.get("https://www.google.com/")
html = driver.page_source
print(html)
This works
Lambda
I then zip my chromedriver and Chrome files:
mkdir tmp
mv chromedriver tmp
mv chrome tmp
cd tmp
zip -r9 ../chrome.zip chromedriver chrome
And copy the zipped file to an S3 bucket
This is my lambda function:
import os
import boto3
from botocore.exceptions import ClientError
import zipfile
import selenium
from selenium import webdriver
s3 = boto3.resource('s3')
def handler(event, context):
chrome_bucket = os.environ.get('CHROME_S3_BUCKET')
chrome_key = os.environ.get('CHROME_S3_KEY')
# DOWNLOAD HEADLESS CHROME FROM S3
try:
# with open('/tmp/headless_chrome.zip', 'wb') as data:
s3.meta.client.download_file(chrome_bucket, chrome_key, '/tmp/chrome.zip')
print(os.listdir('/tmp'))
except ClientError as e:
raise e
# UNZIP HEADLESS CHROME
try:
with zipfile.ZipFile('/tmp/chrome.zip', 'r') as zip_ref:
zip_ref.extractall('/tmp')
# FREE UP SPACE
os.remove('/tmp/chrome.zip')
print(os.listdir('/tmp'))
except:
raise ValueError('Problem with unzipping Chrome executable')
# CHANGE PERMISSION OF CHROME
try:
os.chmod('/tmp/chromedriver', 0o775)
os.chmod('/tmp/chrome/chrome', 0o775)
os.chmod('/tmp/chrome/google-chrome', 0o775)
except:
raise ValueError('Problem with changing permissions to Chrome executable')
# GET LINKS
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--headless')
chrome_options.add_argument('--window-size=1280x1696')
chrome_options.add_argument('--disable-gpu')
chrome_options.add_argument('--disable-dev-shm-usage')
chrome_options.add_argument('--hide-scrollbars')
chrome_options.add_argument('--enable-logging')
chrome_options.add_argument('--log-level=0')
chrome_options.add_argument('--v=99')
chrome_options.add_argument('--single-process')
chrome_options.add_argument('--ignore-certificate-errors')
chrome_options.add_argument('--remote-debugging-port=9222')
chrome_options.binary_location = "/tmp/chrome/google-chrome"
driver = webdriver.Chrome(
executable_path = "/tmp/chromedriver",
chrome_options=chrome_options
)
driver.get("https://www.google.com/")
html = driver.page_source
print(html)
I'm able to see my unzipped files in the /tmp path.
And my error:
{
"errorMessage": "Message: unknown error: unable to discover open pages\n",
"errorType": "WebDriverException",
"stackTrace": [

}
EDIT: I am willing to try out anything at this point. Different versions of Chrome or Chromium, Chromedriver, Python or Selenium.
EDIT2: The answer below did not solve the problem.
