Amazon CloudWatch Synthetics now supports Environment Variables

CloudWatch Synthetics now supports the use of environment variables with canaries. This allows you to save time by using a single canary script to create different canaries that have a similar task.

Canaries are modular, lightweight scripts that you can configure to run on a schedule in order to monitor your endpoints and APIs from the outside-in. With this release, you can now use environment variables to extend a single canary script to create multiple canaries with different values. For example, if you have endpoints such as prod, dev, and pre-release for the different stages of your software development and you need to create canaries to test each of these endpoints, you can use this new functionality to write a single canary script that tests your application and then specify different values for the endpoint environment variable to create each of the three canaries.
