CloudBees action: Scan with Grype

Use this action to perform static application security testing (SAST) on code with Grype. Grype, an open-source scanning tool, finds vulnerabilities in container images and filesystems. You can also use the action output as a quality gate for the next step or job in your workflow.

All CloudBees action repositories are listed at CloudBees, Inc. on GitHub.

Inputs

Input name Data type Required? Description

binary-tar-path

String

Yes

The path of the binary to be scanned.

The binary file must be in the TAR format.

Outputs

Table 2. Output details
Output name	Data type	Description
`critical-count`	String	The number of Critical security findings discovered during the scan.
`very-high-count`	String	The number of Very high security findings discovered during the scan.
`high-count`	String	The number of High security findings discovered during the scan.
`medium-count`	String	The number of Medium security findings discovered during the scan.
`low-count`	String	The number of Low security findings discovered during the scan.

Usage examples

Basic example

The following is a basic example of using the action:

      - name: Scan with Grype
        uses: cloudbees-io/grype-plugin@v1
        with:
          binary-tar-path: /path/to/binary.tar▼

Using the action output

Access the output values in downstream steps and jobs using the outputs context.

Use the output in your workflow as follows, where <action_step_ID> is the action step ID, and <severity> is an output parameter name, such as critical-count:

${{steps.<action_step_ID>.outputs.<severity>}}▼

The following example uses the action output in a downstream step of the same job:

name: my-workflow

  push:
    branches:
      - main

      - name: source dir examine

        shell: sh

        run: |
            #printing all outputs
            echo "Outputs from upstream grype step:"
            echo "Critical count: ${{steps.grype-step.outputs.critical-count}}"
            echo "Very high count: ${{steps.grype-step.outputs.very-high-count}}"
            echo "High count: ${{steps.grype-step.outputs.high-count}}"
