PyChromeless
Python (selenium) Lambda Chromium Automation (naming pending)
PyChromeless allows to automate actions to any webpage from AWS Lambda. The aim of this project is to provide the scaffolding for future robot implementations.
But... how?
All the process is explained here. Technologies used are:
- Python 3.6
- Selenium
- Chrome driver
- Small chromium binary
Requirements
Install docker and dependencies:
make fetch-dependencies
- Installing Docker
- Installing Docker compose
Working locally
To make local development easy, you can use the included docker-compose.
Have a look at the example in lambda_function.py
: it looks up “21 buttons” on Google and prints the first result.
Run it with: make docker-run
Building and uploading the distributable package
Everything is summarized into a simple Makefile so use:
make build-lambda-package
- Upload the
build.zip
resulting file to your AWS Lambda function - Set Lambda environment variables (same values as in docker-compose.yml)
PYTHONPATH=/var/task/src:/var/task/lib
PATH=/var/task/bin
- Adjust lambda function parameters to match your necessities, for the given example:
- Timeout: +10 seconds
- Memory: + 250MB
