Regula

Introduction

Regula is a tool that evaluates infrastructure as code files for potential AWS, Azure, Google Cloud, and Kubernetes security and compliance violations prior to deployment.

Regula supports the following file types:

CloudFormation JSON/YAML templates
Terraform source code
Terraform JSON plans
Kubernetes YAML manifests
Azure Resource Manager (ARM) JSON templates (in preview)

Regula includes a library of rules written in Rego, the policy language used by the Open Policy Agent (OPA) project. Regula works with your favorite CI/CD tools such as Jenkins, Circle CI, and AWS CodePipeline; we’ve included a GitHub Actions example so you can get started quickly. Where relevant, we’ve mapped Regula policies to the CIS AWS, Azure, Google Cloud, and Kubernetes Foundations Benchmarks so you can assess compliance posture. Regula is maintained by engineers at Fugue.

Regula is also available as a Docker image on DockerHub here.

More information is available at regula.dev.

Installation

Homebrew (macOS & Linux)

To install Regula via Homebrew:

brew tap fugue/regula
brew install regula

Prebuilt binary (all platforms)

Download the Regula archive for your platform from the Releases page.
Extract the downloaded archive.

Move the extracted regula binary to somewhere in your PATH:

macOS:

mv regula /usr/local/bin

Linux:

sudo mv regula /usr/local/bin

Windows (cmd):

md C:\regula\bin
move regula.exe C:\regula\bin
setx PATH "%PATH%;C:\regula\bin"

Windows (PowerShell):

md C:\regula\bin
move regula.exe C:\regula\bin
$env:Path += ";C:\regula\bin"
# You can add '$env:Path += ";C:\regula\bin"' to your profile.ps1 file to
# persist that change across shell sessions.

Windows users only: Close cmd and re-open it so the changes take effect.
You can now run regula.

Docker (all platforms)

Regula is available as a Docker image on DockerHub here.

For usage, see Running Regula with Docker.
