Apart from the various programming package management systems, Debricked also supports package managers for various Linux distributions, allowing you to find and monitor potential vulnerabilities of your server or Docker container.
To start tracking your server/Docker vulnerabilities, you need to first execute your package manager(s) list command and redirect the output to a text file:
for Debian, Ubuntu and most derivatives:
apt list --installed > apt.list
for Alpine Linux, widely used by Docker containers
apk list --installed > apk.list
To scan them for dependencies, the outputted file(s) should then either be committed to your repository or manually uploaded.
