-    This workflow runs on every commit and is composed of a set of unit tests on the infrastructure code. It runs [terraform fmt]( https://www.terraform.io/cli/commands/fmt) to ensure the code is properly linted and follows terraform best practices. Next it performs [terraform validate](https://www.terraform.io/cli/commands/validate) to check that the code is syntactically correct and internally consistent. Lastly, [checkov](https://github.com/bridgecrewio/checkov), an open source static code analysis tool for IaC, will run to detect security and complaince issues. If the repository is utilizing GitHub Advanced Security (GHAS), the results will be uploaded to GitHub.

Create an environment named `production` by following these [insturctions](https://docs.github.com/actions/deployment/targeting-different-environments/using-environments-for-deployment#creating-an-environment). On the `production` environment setup a protection rule and add any required approvers you want that need to sign off on production deployments. You can also limit the environment to your main branch. Detailed instructions can be found [here](https://docs.github.com/en/actions/deployment/targeting-different-environments/using-environments-for-deployment#environment-protection-rules).
