Help me with the example of using environment variables with values for checkov and terrascan

[babuga365]

I'm getting issues for using below setup

Azure Devops Pipeline: ci.yaml

parameters:
  - name: workingDir
    type: string

stages:
- stage: TerraformContinuousIntegration
  displayName: Terraform - CI
  jobs:
    - job: StaticCodeAnalysis
      displayName: CI - Static Code Analysis 
      pool:
        vmImage: ubuntu-latest
      steps:
      - task: MicrosoftSecurityDevOps@1
        displayName: 'Static Code Analysis - MDFC'
        inputs:
          categories: 'IaC'
          tools: 'checkov,terrascan'
        env:
          GDN_CHECKOV_DIRECTORY:'$(System.DefaultWorkingDirectory)/${{ parameters.workingDir }}'
          GDN_CHECKOV_SKIPPATH: '/pipelines,/examples,/archive'
          GDN_CHECKOV_DOWNLOADEXTERNALMODULES: 'true'
          GDN_CHECKOV_CREATECONFIG: 'checkov-config.yaml'
          GDN_CHECKOV_SHOWCONFIG: 'true'
          GDN_CHECKOV_SKIPCHECK: 'CKV_TF_1'

Logs:

If you see the logs, the checkov is still using directory as: --directory ./ instead of value from environment variable: GDN_CHECKOV_DIRECTORY

Also let me know, If I'm okay to use this env variable: GDN_CHECKOV_SKIPPATH with values like this: '/pipelines,/examples,/archive'. Because checkov is not skipping this path correctly and checking all the files from this directory as well.

Same issue here.

It looks like the GDN_CHECKOV_DIRECTORY and the GDN_CHECKOV_FILE are not working for me. All other environment variables seem to be working except those two.

Can someone please fix this issue?

We need this too. Can someone please fix this? Ping @chrisnielsen-MS @richardtucker @sethRait or anyone from MS.

Hi folks,

With regards to the target directory, that one does work but it has a different environment variable: GDN_CHECKOV_TARGETDIRECTORY

I noticed our wiki had GDN_CHECKOV_DIRECTORY as well, so I fixed the documentation there. With regards to the skip paths, Checkov expects multiple values to be specified separately, like --skip-path /pipelines --skip-path /examples. This is currently not supported by our mechanism of passing values through environment variables, but we plan to add proper support for this soon in an upcoming release.

@cndaan -- we currently do not support the GDN_CHECKOV_FILE argument as it is mutually exclusive with --directory, for which we provide a default value. Once we have proper support for skipping subdirectories, would you still be interested in support for scanning a single file? If there is interest in this scenario separate from avoiding unnecessary scanning, I will add it to our backlog as well.

[masse-solita]

@chrisnielsen-MS To my knowledge Checkov doesn't support scanning Terraform execution plans without the file argument.

From the Checkov documentation: "Plan evaluation provides Checkov additional dependencies and context that can result in a more complete scan result." https://www.checkov.io/7.Scan%20Examples/Terraform%20Plan%20Scanning.html

Thank you for confirming @masse-solita we will be addressing this in an upcoming release as well.

Great news @chrisnielsen-MS! Any ETA on the new release? 😄
