Behind the scenes

How are identified applicable files

  • If this linter is active, all files will always be linted

How the linting is performed

trivy is called once on the whole project directory (project CLI lint mode)

  • filtering can not be done using MegaLinter configuration variables,it must be done using trivy configuration or ignore file (if existing)
  • VALIDATE_ALL_CODEBASE: false does not make trivy analyze only updated files

Example calls

trivy fs --security-checks vuln,config .
