AWS Cloudwatch synthetics – how to install external dependencies for runnning canaries
Question:
I have a python selenium script that needs a third party library (‘redis’ package for instance).
I would like to run this script as an AWS cloudwatch synthetic canary. But it fails because it does not have this library installed.
