CodeQL step configuration
You can ingest scan results from CodeQL into Harness STO. The following steps outline the basic workflow:
-
Run a CodeQL scan, either externally or as part of a Run step, and publish the results to SARIF.
-
Add the SARIF data to your pipeline. If you ran the scan outside the pipeline, do the following:
-
In the stage where you ingest the results, go to Overview > Shared Paths and create a folder under
/sharedsuch as/shared/scan_results. -
Use a Run step to add your scan results to the shared folder.
-
-
Use a CodeQL step to ingest the results.
This topic includes an end-to-end YAML pipeline that illustrates this workflow.
Important notes for running CodeQL scans in STO
Root access requirements
If you want to add trusted certificates to your scan images at runtime, you need to run the scan step with root access.
You can utilize custom STO scan images and pipelines to run scans as a non-root user. For more details, refer Configure your pipeline to use STO images from private registry.
For more information
The following topics contain useful information for setting up scanner integrations in STO:
CodeQL step settings for STO scans
The recommended workflow is to add a CodeQL step to a Security or Build stage and then configure it as described below.
Scan
Scan mode
- Ingestion Configure the step to read scan results from a data file and then ingest, normalize, and deduplicate the data.
Scan configuration
The predefined configuration to use for the scan. All scan steps have at least one configuration.
Target
Type
-
Repository Scan a codebase repo.
In most cases, you specify the codebase using a code repo connector that connects to the Git account or repository where your code is stored. For information, go to Configure codebase.
Target and Variant Detection
When Auto is enabled for code repositories, the step detects these values using git:
- To detect the target, the step runs
git config --get remote.origin.url. - To detect the variant, the step runs
git rev-parse --abbrev-ref HEAD. The default assumption is that theHEADbranch is the one you want to scan.
Note the following:
- Auto is not available when the Scan Mode is Ingestion.
- Auto is the default selection for new pipelines. Manual is the default for old pipelines, but you might find that neither radio button is selected in the UI.
Name
The identifier for the target, such as codebaseAlpha or jsmith/myalphaservice. Descriptive target names make it much easier to navigate your scan data in the STO UI.
It is good practice to specify a baseline for every target.
Variant
The identifier for the specific variant to scan. This is usually the branch name, image tag, or product version. Harness maintains a historical trend for each variant.
Ingestion file
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 results files 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
Log Level
The minimum severity of the messages you want to include in your scan logs. You can specify one of the following:
- DEBUG
- INFO
- WARNING
- ERROR
Additional CLI flags
Use this field to run the CodeQL scanner binary with additional flags.
Passing additional CLI flags is an advanced feature. Harness recommends the following best practices:
-
Test your flags and arguments thoroughly before you use them in your Harness pipelines. Some flags might not work in the context of STO.
-
Don't add flags that are already used in the default configuration of the scan step.
To check the default configuration, go to a pipeline execution where the scan step ran with no additional flags. Check the log output for the scan step. You should see a line like this:
Command [ scancmd -f json -o /tmp/output.json ]In this case, don't add
-for-oto Additional CLI flags.
Fail on Severity
Every STO scan step has a Fail on Severity setting. If the scan finds any vulnerability with the specified severity level or higher, the pipeline fails automatically. You can specify one of the following:
CRITICALHIGHMEDIUMLOWINFONONE— Do not fail on severity
The YAML definition looks like this: fail_on_severity : critical # | high | medium | low | info | none
Settings
You can use this field to specify environment variables for your scanner.
Additional Configuration
The fields under Additional Configuration vary based on the type of infrastructure. Depending on the infrastructure type selected, some fields may or may not appear in your settings. Below are the details for each field
- Override Security Test Image
- Privileged
- Image Pull Policy
- Run as User
- Set Container Resources
- Timeout
Advanced settings
In the Advanced settings, you can use the following options:
CodeQL pipeline example
The following pipeline illustrates a simple ingestion scan. It consists of two steps. A Run step generates an example CodeQL data file in SARIF format. A CodeQL step then ingests the data.
