Regula is an open-source static code analysis tool for Terraform maintained by Fugue. It checks for misconfigurations terraform, cloudformation, and kubernetes files. Which can be useful when you wish to test a variety of different infrastructure as code files for misconfigurations.
Getting started with regula is as simple as regula run . to scan the current directory recursively. Regula will immediately begin to scan your IaC and identify the locations of those misconfigurations.
