Here is a small Python library and command line utility, to track how outdated (how many updates you are missing), vulnerable and buggy the packages you use in your container are.
For now, the tool analyze only Debian (for outdateness, vulnerabilities and bugs) and npm packages (for outdateness), but it will support other package repositories.
If you use the tool as a Python library you can have many details about the package issues as Pandas dataframes, but if you only use it as a command line, you will only have an overview on the state of the packages.
