Vulnerability DB

Skip update of vulnerability DB

Trivy downloads its vulnerability database every 12 hours when it starts operating. This is usually fast, as the size of the DB is only 10~30MB. But if you want to skip even that, use the --skip-db-update option.

$ trivy image --skip-db-update python:3.4-alpine3.9

Only download vulnerability database

You can also ask Trivy to simply retrieve the vulnerability database. This is useful to initialize workers in Continuous Integration systems.

$ trivy image --download-db-only
