[Bug] how to mount volume in analyzer docker container?

Describe the bug
my issue is related to the closed #707

I seem to have the very same issue, running cortex 3.1.0 installed ubuntu package, and the analyzers as docker images.
I followed example here to create volume and git cloned the blocklists,
http://dockerlabs.collabnix.com/beginners/volume/creating-volume-mount-from-dockercli.html

However, when the analyzer runs, I get

{
  "hits": [],
  "count": 0
}

as the docker image doesn't mount it. Looking at the code, i guess that's expected when the analyzer doesn't find any of the iplist or netlist files.

As I run the cortex not as a docker container, there's no docker-compose to tweak.

I guess I'm missing the last step, wonder how to tell cortex to use/mount the given volume when starting up the analyzer. Any clue?

Expected behavior
I would like to be able to share a host folder/volume with cortex analyzer.

Work environment

• Client OS:
• Server OS: Ubuntu 20.04.2
• Browse type and version:
• Cortex version: 3.1.0-1 Ubuntu Packages
• Cortex Analyzer/Responder name: FireHOLBlocklists
• Cortex Analyzer/Responder version: 2.0

Start with the Cortex 3.1.0 configuration and the Docker invocation for the FireHOLBlocklists analyzer, then compare the setup with the closed #707 issue. Verify whether the host folder or Docker volume is visible inside the analyzer and whether the blocklist files are detected; done means a host-mounted blocklist produces non-empty results.
