What will you learn?

In this comprehensive tutorial, you will master the art of deploying a Python Flask application that harnesses the power of Playwright on Google Cloud Run. By following step-by-step instructions, you will learn how to containerize your app and configure it for seamless deployment in a serverless environment.

Introduction to the Problem and Solution

Deploying a Python Flask app that incorporates Playwright on Google Cloud Run presents challenges due to the intricacies of running browser automation in serverless environments. However, by leveraging containerization techniques and configuring Google Cloud Run settings effectively, we can overcome these obstacles and successfully deploy our application.

To tackle this challenge: 1. Containerize the Python Flask app along with its dependencies, including Playwright. 2. Configure deployment settings in Google Cloud Run for optimal performance in a serverless environment.

Code

# Import necessary libraries
from flask import Flask

app = Flask(__name__)

@app.route('/')
def hello_world():
    return 'Hello, World!'

if __name__ == '__main__':
    app.run(debug=True)
