Checkly is now listed on the official Terraform Registry, and John Arundel introduces the Checkly Terraform provider in a guest article. The provider allows users to automate and manage synthetic monitoring with Checkly using Terraform. Terraform helps build, modify, and manage infrastructure safely and efficiently. It describes resources using a simple text file that can be stored and versioned alongside application code. The Checkly Terraform provider connects Terraform to the necessary API to provision resources. Users need to configure their API key and initialize Terraform before creating checks. They can plan and apply changes, making it easy to manage infrastructure with Terraform. The process allows users to create new checks from scratch or modify existing ones. Once managing all checks with Terraform code, users should avoid manual changes using the web interface to maintain consistency. With this setup, users can automate their synthetic monitoring with Checkly using Terraform and enjoy a more efficient workflow.
