CloudBees action: Scan Go code with Gosec

Use this action to perform static application security testing (SAST) on Go repositories with the open-source Golang Security Checker (Gosec). Gosec inspects Go code for security problems by scanning the AST and SSA code representation. 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.

Usage examples

Basic example

The following is a basic example of using the action:

      - name: Scan with Gosec
        uses: cloudbees-io/gosec-plugin@v1▼

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
kind: workflow
apiVersion: automation.cloudbees.io/v1alpha1

on:
  push:
    branches:
      - main

permissions:
  scm-token-own: read
  scm-token-org: read
  id-token: write

jobs:
  gosec-scan-job:
    steps:
      - name: check out source code
        uses: cloudbees-io/checkout@v1

      - id: gosec-step
        name: gosec scan
        uses: cloudbees-io/gosec-plugin@v1

      - name: source dir examine
        uses: docker://golang:1.20.3-alpine3.17
        shell: sh
        run: |
          ls -latR /cloudbees/workspace

      - id: print-outputs-from-gosec-step
        name: print outputs from upstream gosec step
        uses: docker://alpine:latest
        run: |
            #printing all outputs
            echo "Outputs from upstream gosec step:"
            echo "Critical count: ${{steps.gosec-step.outputs.critical-count}}"
            echo "Very high count: ${{steps.gosec-step.outputs.very-high-count}}"
            echo "High count: ${{steps.gosec-step.outputs.high-count}}"
            echo "Medium count: ${{steps.gosec-step.outputs.medium-count}}"
            echo "Low count: ${{steps.gosec-step.outputs.low-count}}"▼
