Create a ScanTemplate

The ScanTemplate custom resource (CR) defines the Pod with the scanner image that you use for vulnerability scanning. There’s a default scanner image you can use out-of-the-box.

Structure

apiVersion: scanning.apps.tanzu.vmware.com/v1beta1
kind: ScanTemplate
spec:
    # Required. This field must specify a valid pod.spec.
    # This has the instructions for the scan to be successfully executed.
    # See Pod Requirements section below for more details
    template:

Pod requirements

You can define any valid Kubernetes Pod into the ScanTemplate CR if you follow these requirements:

  1. Scanner Container
    The Pod scan must define a container named scanner to hold the scanning result.

    • stdout Logs
      The scan result must be printed in the stdout of the scanner container having a valid CycloneDX XML format.
  2. XML Extra Fields
    Component Name
    For the scan controller to keep track of your report, provide the name of the scanned artifact in the bom>metadata>component>name field of the XML generated as an output. Use the url for a source repository. Use the image name for an image scan. Component Digest
    For the Scan Controller to keep track of your report, provide your artifact’s digest or most unique identifier of your artifact into the bom>metadata>component>version field of the XML generated as an output.
    Scanner Name
    Provide the name of the scanner you are using in the bom>metadata>tools>tool>name field of the XML generated as an output.
    Scanner Vendor
    Provide the name of the vendor from the scanner that you are using in the bom>metadata>tools>tool>vendor field of the XML generated as an output.
    Scanner Version
    Provide the version of the scanner you are using in bom>metadata>tools>tool>version field of the XML generated as an output.

If the scanner Pod is not defined or the logs retrieved from the stdout do not have a valid format, the scanning condition fails.

Best practices

  1. SourceScan
    • Init Container
      If you’re doing a SourceScan, we recommend defining the cloning of the repository in an init container named repo. Any output in stdout in this init container is prompted if an error occurs, so you can have more context about what failed inside the job.
