HashiCorp has announced that Terraform Sentinel policies are now available in the Terraform Registry, allowing users to publish and share policies they want to use. The Registry provides a centralized location for searching and accessing Sentinel policies, with features such as filtering by provider and category. Users can browse policy libraries, select policies to use, and copy code to add it to their Terraform Cloud workspace configuration. Publishing policies is similar to publishing Terraform modules, requiring users to log in with their GitHub account and assign a category and providers. The Registry extracts information about the policy library from the source repository, making it available via the UI or API. This move aims to build out the Terraform ecosystem by leveraging community contributions and providing a platform for example and best-practice policies.
