Skipping Files and Directories
This section details ways to specify the files and directories that Trivy should not scan.
Skip Files
| Scanner | Supported |
|---|---|

By default, Trivy traverses directories and searches for all necessary files for scanning.
You can skip files that you don't maintain using the --skip-files flag.
$ trivy image --skip-files "/Gemfile.lock" --skip-files "/var/lib/gems/2.5.0/gems/http_parser.rb-0.6.0/Gemfile.lock" quay.io/fluentd_elasticsearch/fluentd:v2.9.0
It's possible to specify globs as part of the value.
$ trivy image --skip-files "./testdata/*/bar" .
Will skip any file named bar in the subdirectories of testdata.
Skip Directories

By default, Trivy traverses directories and searches for all necessary files for scanning.
You can skip directories that you don't maintain using the --skip-dirs flag.
$ trivy image --skip-dirs /var/lib/gems/2.5.0/gems/fluent-plugin-detect-exceptions-0.0.13 --skip-dirs "/var/lib/gems/2.5.0/gems/http_parser.rb-0.6.0" quay.io/fluentd_elasticsearch/fluentd:v2.9.0
It's possible to specify globs as part of the value.
$ trivy image --skip-dirs "./testdata/*" .
Will skip all subdirectories of the testdata directory.
Tip
Glob patterns work with any trivy subcommand (image, config, etc.) and can be specified to skip both directories (with --skip-dirs) and files (with --skip-files).
Advanced globbing
Trivy also supports the globstar pattern matching.
$ trivy image --skip-files "**/foo" image:tag
Will skip the file foo that happens to be nested under any parent(s).
File patterns

When a directory is given as an input, Trivy will recursively look for and test all files based on file patterns. The default file patterns are here.
In addition to the default file patterns, the --file-patterns option takes regexp patterns to look for your files.
For example, it may be useful when your file name of Dockerfile doesn't match the default patterns.
This can be repeated for specifying multiple file patterns.
A file pattern contains the analyzer it is used for, and the pattern itself, joined by a semicolon. For example:
--file-patterns "dockerfile:.*.docker" --file-patterns "kubernetes:*.tpl" --file-patterns "pip:requirements-.*\.txt"
The prefixes are listed here
