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

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

Reset

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
