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
Result
2019-05-16T12:48:08.703+0900 INFO Detecting Alpine vulnerabilities...
python:3.4-alpine3.9 (alpine 3.9.2)

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
Lightweight DB
The lightweight DB doesn't contain vulnerability detail such as descriptions and references. Because of that, the size of the DB is smaller and the download is faster.
This option is useful when you don't need vulnerability details and is suitable for CI/CD. To find the additional information, you can search vulnerability details on the NVD website. https://nvd.nist.gov/vuln/search
$ trivy image --light alpine:3.10
--light
option doesn't display titles like the following example.
