Clair scanner reference for STO



You can scan container images and ingest results from Clair.

Workflow descriptions​

Ingestion workflows

This workflow applies to scanner integrations that support Ingestion mode.

  1. Add a Build or Security stage to your pipeline.

  2. Add a Run step and set it up to save your scan results to a shared folder.

    For more information, go to Run an ingestion scan in an STO Pipeline.

  3. Add a Custom Scan step.

  4. Review the Important notes for Custom Scan steps for additional requirements and relevant information.

  5. Add the relevant key:value pairs to Settings.

Orchestration/extraction workflows

This workflow applies to scanner integrations that support orchestratedScan or dataLoad scan modes.

  1. Add a Build or Security stage to your pipeline.

  2. If you're scanning a code repository, set up your codebase.

  3. Add a Custom Scan step.

  4. Review the Important notes for Custom Scan steps for additional requirements and relevant information.

    If you're setting up a scan on a Kubernetes or Docker build infrastructure, you need to add a Docker-in-Docker background step to the stage.

  5. Add the relevant key:value pairs to Settings.

Custom Scan step settings for Clair​

Scanner settings​

These settings are required.

Product name​

The scanner name. This is required for all Custom Scan steps.

Key​
product_name
Value​
docker_image_scan

Scan type​

The target type to scan.

Key​
scan_type
Value​
containerImage

Policy type​

The scan mode to use.

Key​
policy_type
Value​

Must be one of the following.

orchestratedScan
ingestionOnly

Product config name​

Key​
product_config_name
Value​
default

Product access​

These settings are available to access the Clair API when policy_type is orchestratedScan.

You should create Harness text secrets for your encrypted passwords and tokens and reference them using the format <+secrets.getValue("my-access-token")>.

product_url
product_access_id
product_access_token

Target and variant​

Every Custom Scan step needs a target and baseline.

Target name​

Key​
target_name
Value​

A user-defined label for the code repository, container, application, or configuration to scan. Specify a unique, descriptive name. This makes it much easier to navigate your scan results in the STO UI.

Target variant​

Key​
target_variant
Value​

A user-defined label for the branch, tag, or other target variant to scan.

Container scan settings​

These settings apply to Custom Scan steps when both of these conditions are true:

  1. The policy_type is orchestratedScan or dataLoad.
  2. The scan_type is containerImage.

Container type​

Key​
container_type
Value​

The registry type where the image is stored. Specify one of the following:

Scan a local image built and stored within the context of the current stage (via /var/run/docker.sock registered as a stage level volume mount).

local_image

A registry that uses the Docker Registry v2 API such as Docker Hub, Google Container Registry, or Google Artifact Registry.

docker_v2

JFrog Docker Registry.

jfrog_artifactory

Amazon Container Registry.

aws_ecr

Container domain​

Key​
container_domain
Value​

The URL of the registry that contains the image to scan. Examples include:

docker.io
app.harness.io/registry
us-east1-docker.pkg.dev
us.gcr.io

Container project​

Key​
container_project
Value​

The image name. For non-local images, you also need to specify the image repository. Example: jsmith/myalphaservice

Container tag​

Key​
container_tag
Value​

The image tag. Examples: latest, 1.2.3

Container access Id​

Key​
container_access_id
Value​

Your access Id to the image registry.

Container access token​

Key​
container_access_token
Value​

The password or access token used to log in to the image registry. In most cases this is a password or an API key.

You should create a Harness text secret with your encrypted token and reference the secret using the format <+secrets.getValue("container-access-id")>. For more information, go to Add and Reference Text Secrets.

AWS region​

Key​
container_region
Value​

The region where the image to scan is located, as defined by the cloud provider such as AWS.

Ingestion file​

This setting applies to Custom Scan steps when the policy_type is ingestionOnly.

Key​
ingestion_file
Value​

The path to your scan results when running an Ingestion scan, for example /shared/scan_results/myscan.latest.sarif.

  • The data file must be in a supported format for the scanner.

  • The data file must be accessible to the scan step. It's good practice to save your scan results to a shared path in your stage. In the visual editor, go to the stage where you're running the scan. Then go to Overview > Shared Paths. You can also add the path to the YAML stage definition like this:

        - stage:
          spec:
            sharedPaths:
              - /shared/scan_results

Fail on Severity​

If the scan finds any vulnerability with the specified severity level or higher, the pipeline fails automatically. NONE means do not fail on severity.

For more information, go to Stop builds based on scan results.

Key​
fail_on_severity
Value​
CRITICAL
MEDIUM
LOW
INFO
NONE
