Best way to run Docker in Proxmox?

I found this guide here:

https://www.servethehome.com/creating-the-ultimate-virtualization-and-container-setup-with-management-guis/

The authors themselves call the set-up a "security nightmare" and unsuitable for production mode.

So my question is, does anybody know of a reliable way to run docker containers in Proxmox?

I'm looking to deploy Zoneminder and their "easiest" method is with a docker image:

https://zoneminder.readthedocs.io/en/1.34.9/installationguide/easydocker.html

I'm not sure if there's any benefit to running the docker image directly vs. running a docker container inside an Ubuntu server VM vs. just installing Zoneminder straight on the VM. I'm going to post over in r/ZoneMinder and ask.
