Running headless mode selenium in Docker Container then pushing image in Amazon ECR.
What is Amazon ECR?
Amazon Elastic Container Registry (ECR) is a fully managed Docker container registry that makes it easy to store, share, and deploy container images.
What is Docker container?
A Docker container image is a lightweight, standalone, executable package of software that includes everything needed to run an application: code, runtime, system tools, system libraries and settings.
File Structure
── /MyFolder/ # root folder

Code
Copy the following inside main_test.py
import unittest
from selenium import webdriver

class app_test_case(unittest.TestCase):
def setUp(self):
chromeOptions = webdriver.ChromeOptions()
driver_path = '/usr/local/bin/chromedriver'
chromeOptions.add_argument('--headless')

chromeOptions.add_argument('--no-sandbox')
self.driver = webdriver.Chrome(driver_path, chrome_options=chromeOptions)
self.driver.implicitly_wait(30)
self.driver.maximize_window()

self.base_url = path
def test_i_d_e_script1(self):

driver.get(self.base_url)
get_title = driver.title
print(get_title, " ", len(get_title))
def tearDown(self):
sleep(5)
self.driver.quit()
if __name__ == "__main__":

Copy the following inside requirements.txt
selenium==3.12.0
ipython==7.0.1
Copy the following inside Dockerfile
FROM python:3

RUN pip install --upgrade pip

Build and Run New Docker Image
Once Dockerfile and all required config files have been created, we can now build a new docker image
$ docker build -t myapp .
Check created image
$ docker images
Run image
$ docker run myapp
Output should be like this:
Pushing Image in Amazon ECR
Step 1. Authenticate your Docker client to the Amazon ECR registry to which you intend to push your image
$ aws ecr get-login --region region --no-include-email
Step 2. Copy and paste the docker login command into a terminal to authenticate your Docker CLI to the registry.
Step 3. Tag your image with the Amazon ECR registry, repository, and optional image tag name combination to use. The registry format is: docker tag image_id aws_account_id.dkr.ecr.region.amazonaws.com/myapp
$ docker tag image_id aws_account_id.dkr.ecr.region.amazonaws.com/myapp
(Note: You must first create a repository in ECR)
Step 4. Create a repository in AWS ECS
Step 5. Push the image using the docker push command: The registry format is: docker tag image_id aws_account_id.dkr.ecr.region.amazonaws.com/myapp
$ docker push aws_account_id.dkr.ecr.region.amazonaws.com/myapp
