I'm trying to run security scan on docker images with Trivy. Docker run throws error
failed to download vulnerability DB: DB file not found
any reason why?
Command:
$ mkdir /tmp/trivy
$ docker run --rm -v /tmp/trivy:/root/.cache/ aquasec/trivy python:3.4-alpine
Error:
2021-03-03T09:55:22.770Z WARN You should avoid using the :latest tag as it is cached. You need to specify '--clear-cache' option when :latest image is changed

As ridiculous as it sounds. It turned out that my network was blocking download. Switching to tethered internet from my mobile device solved the problem.
