CloudWatch Synthetics now supports the use of environment variables with canaries. You can save time by using a single canary script to create different canaries that have a similar task.
Canaries are modular, lightweight scripts that you 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 production, development, and pre-release for the different stages of your software development, and you want 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 specify different values for the endpoint environment variable to create each of the three canaries.
