Integrate Checkov with Github Actions

Integrating Checkov into GitHub Actions provides a simple, automatic way of applying policies to your Terraform code both during pull request review and as part of any build process.

Use a Checkov Action from the Marketplace

Check out our pre-made action.

Create Your Own Action: Basic Set-up

Add a new step in the workflow.yml.

├───.github
│   └───workflows

Here is a basic example:

---
name: Checkov
on:
  push:
    branches:
      - master
jobs:
  build:

    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - name: Set up Python 3.8
        uses: actions/setup-python@v1
        with:
          python-version: 3.8
      - name: Test with Checkov
        id: checkov
        uses: bridgecrewio/checkov-action@master
        with:
          directory: example/examplea
          framework: terraform 

Example Results

Any time after you push your code to GitHub, it will run your job. If Checkov finds any errors, it will fail the build.

Action Failure

In the original examples code, the file aws_efs_file_system.sharedstore.tf is not set to encrypted:

resource "aws_efs_file_system" "sharedstore" {
  creation_token = var.efs["creation_token"]

  lifecycle_policy {
    transition_to_ia = var.efs["transition_to_ia"]
  }

  kms_key_id                      = var.efs["kms_key_id"]
  encrypted                       = false
  performance_mode                = var.efs["performance_mode"]
  provisioned_throughput_in_mibps = var.efs["provisioned_throughput_in_mibps"]
  throughput_mode                 = var.efs["throughput_mode"]
}

This will fail a Checkov test:

Actions Failure

Pipeline Success

The previous error can be fixed by setting the value of encryption to true. Actions success
