GitLab Instructions

Make sure you have at least one GitLab Runner available in your Gitlab CI, if using self-managed. Otherwise, using, a Runner is managed for you.

Instructions for getting started with GitLab can be found here.

Create a .gitlab-ci.yml file or update an existing one.

You will need to define the Terraform version to use, for example:


You will also need to specify the directory where your Terraform file exists.

Below, we have an example where the terraform file is contained in one TF file in a directory:

  TEST_ROOT:  ${CI_PROJECT_DIR}/test/aws/terraform/ec2_role_share_rule/public_and_private_ec2_same_role

Prepare the scan by moving to the directory:

  - cd ${TEST_ROOT}

Define the stages for running the scan. The first step is to run Terraform plan, then run Cloudrail (using the Cloudrail CLI container). Below is a sample.:

  - init_and_plan
  - cloudrail

  stage: init_and_plan
    - terraform init
    - terraform plan -out=plan.out
    name: "$CI_JOB_NAME"
      - ./**/plan.out
      - ./**/.terraform

  stage: cloudrail
  image: indeni/cloudrail-cli:latest
    - cloudrail run --tf-plan plan.out --directory . --origin ci --build-link "$CI_PROJECT_URL/-/jobs/$CI_JOB_ID"  --execution-source-identifier "$CI_COMMIT_BRANCH - $CI_JOB_ID" --output-format json-gitlab-sast --output-file ${CI_PROJECT_DIR}/cloudrail-sast-report.json --auto-approve
      - cloudrail-sast-report.json

This will run Cloudrail and produce a SAST report according to GitLab’s requirements. The idea is that if there are any rules that are set to MANDATE, and they find violations, we will have results listed in the GitLab-SAST output and this will be shown in the Security tab.

If you do not have the “Security Dashboard” feature, you may want to use the Test tab in GitLab, by changing the output format to junit:

  stage: cloudrail
  image: indeni/cloudrail-cli:latest
    - cloudrail run --tf-plan plan.out --directory . --origin ci --build-link "$CI_PROJECT_URL/-/jobs/$CI_JOB_ID"  --execution-source-identifier "$CI_COMMIT_BRANCH - $CI_JOB_ID" --output-format junit --output-file ${CI_PROJECT_DIR}/cloudrail-junit-report.xml --auto-approve

These are the parameters being used:

run – this command will run an evaluation of your Terraform plan.
  • --tf-plan plan.out – here we’re providing Cloudrail with the plan file we generated. This plan file will be analyzed within the container, and then a filtered version of it (without sensitive data) will be uploaded to the Cloudrail Service for analysis.
  • --directory . – Cloudrail needs to know where the root directory of the Terraform files is located.
  • --origin ci – required for all Cloudrail executions within CI.
  • --build-link "$CI_PROJECT_URL/-/jobs/$CI_JOB_ID" – this link will be included in the Cloudrail Web UI when displaying the results of this evaluation (called an Assessment). It will allow you to easily jump to your GitLab job from an Assessment.
  • --execution-source-identifier "$CI_COMMIT_BRANCH - $CI_JOB_ID" – this identifier will show in the Cloudrail Web UI when listing Assessments, to make it easier to determine what job the Assessment was created for.
  • --output-format json-gitlab-sast --output-file ${CI_PROJECT_DIR}/cloudrail-sast-report.json – these two options together will tell Cloudrail to provide the results in GitLab’s SAST format, as well as where to place the file for submission to the GitLab system.
  • --auto-approve – if you would like, you can review the filtered Terraform plan prior to uploading it to the Cloudrail Service for analysis. However, it requires an interactive terminal, which generally isn’t available in CI. Alternatively, you can use the generate-filtered-plan command before run and then employ your own tool to auto-analyze the filtered plan.
  • This command assumes there is an environment variable named CLOUDRAIL_API_KEY that contains the API key for Cloudrail. You can also provide it by using --api-key

This will then cause GitLab to stop the pipeline and provide the list of violations found, allowing developers to fix the violations.

Note that Cloudrail has other output formats as well, but GitLab-SAST is the one intended for GitLab use.

Also note that rules that are set to Advise (which is the default) will not be included in the output by default.
