Overview

trivy-db is a CLI tool and a library to manipulate Trivy DB.

Library

Trivy uses trivy-db internally to manipulate vulnerability DB. This DB has vulnerability information from NVD, Red Hat, Debian, etc.

CLI

The trivy-db CLI tool builds vulnerability DBs. A GitHub Actions workflow periodically builds a fresh version of the vulnerability DB using trivy-db and uploads it to the GitHub Container Registry (see Download the vulnerability database below).

NAME:
   trivy-db - Trivy DB builder

USAGE:
   main [global options] command [command options] image_name

VERSION:
   0.0.1

COMMANDS:
     build    build a database file
     help, h  Shows a list of commands or help for one command

GLOBAL OPTIONS:
   --help, -h     show help
   --version, -v  print the version

Building the DB

You can utilize make db-all to build the database, the DB artifact is outputted to the assets folder.

Alternatively Docker is supported, you can run docker build . -t trivy-db.

If you want to build a trivy integration test DB, please run make create-test-db

Update interval

Trivy DB is built every 6 hours. By default, the update interval specified in the metadata file is 24 hours. If you need to update Trivy DB more frequently, you can upload a new Trivy DB manually.

Download the vulnerability database

version 1 (deprecated)

Trivy DB v1 reached the end of support on February 2023. Please upgrade Trivy to v0.23.0 or later.

Read more about the Trivy DB v1 deprecation in the discussion.

version 2

Trivy DB v2 is hosted on GHCR. Although GitHub displays the docker pull command by default, please note that it cannot be downloaded using docker pull as it is not a container image.

You can download the actual compiled database via Trivy or Oras CLI.

Trivy:

TRIVY_TEMP_DIR=$(mktemp -d)
trivy --cache-dir $TRIVY_TEMP_DIR image --download-db-only
tar -cf ./db.tar.gz -C $TRIVY_TEMP_DIR/db metadata.json trivy.db
rm -rf $TRIVY_TEMP_DIR

oras >= v0.13.0:

$ oras pull ghcr.io/aquasecurity/trivy-db:2

oras < v0.13.0:

$ oras pull -a ghcr.io/aquasecurity/trivy-db:2

The database can be used for Air-Gapped Environment.
