Skip Files

Trivy traversals directories and looks for all lock files by default. If your image contains lock files which are not maintained by you, you can skip the file.

$ trivy image --skip-files "/Gemfile.lock" --skip-files "/var/lib/gems/2.5.0/gems/http_parser.rb-0.6.0/Gemfile.lock"

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

Trivy traversals directories and look for all lock files by default. If your image contains lock files which are not maintained by you, you can skip traversal in the specific directory.

$ 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"

It's possible to specify globs as part of the value.

$ trivy image --skip-dirs "./testdata/*" .

Will skip all subdirectories of the testdata directory.


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 "yaml:deployment" --file-patterns "pip:requirements-.*\.txt"

Exit Code

By default, Trivy exits with code 0 even when vulnerabilities are detected. Use the --exit-code option if you want to exit with a non-zero exit code.

$ trivy image --exit-code 1 python:3.4-alpine3.9
2019-05-16T12:51:43.500+0900    INFO    Updating vulnerability database...
2019-05-16T12:52:00.387+0900    INFO    Detecting Alpine vulnerabilities...

python:3.4-alpine3.9 (alpine 3.9.2)
Total: 1 (UNKNOWN: 0, LOW: 0, MEDIUM: 1, HIGH: 0, CRITICAL: 0)

| openssl | CVE-2019-1543    | MEDIUM   | 1.1.1a-r1         | 1.1.1b-r1     | openssl: ChaCha20-Poly1305     |

This option is useful for CI/CD. In the following example, the test will fail only when a critical vulnerability is found.

$ trivy image --exit-code 0 --severity MEDIUM,HIGH ruby:2.4.0
$ trivy image --exit-code 1 --severity CRITICAL ruby:2.4.0

Exit on EOL

Sometimes you may surprisingly get 0 vulnerabilities in an old image:

  • Enabling --ignore-unfixed option while all packages have no fixed versions.
  • Scanning a rather outdated OS (e.g. Ubuntu 10.04).

An OS at the end of service/life (EOL) usually gets into this situation, which is definitely full of vulnerabilities. --exit-on-eol can fail scanning on EOL OS with a non-zero code. This flag is available with the following targets.

  • Container images (trivy image)
  • Virtual machine images (trivy vm)
  • SBOM (trivy sbom)
  • Root filesystem (trivy rootfs)
$ trivy image --exit-on-eol 1 alpine:3.10

This option is useful for CI/CD. The following example will fail when a critical vulnerability is found or the OS is EOSL:

$ trivy image --exit-code 1 --exit-on-eol 1 --severity CRITICAL alpine:3.16.3


The --reset option removes all caches and database. After this, it takes a long time as the vulnerability database needs to be rebuilt locally.

$ trivy image --reset
