Selfhosted

Just got my first security camera, a Hikvision multi focal 4MP. I got Proxmox up and running and installed Frigate through the community LXC repository on github. Most of the documentation is to first install Docker as LXC and then Frigate as a normal docker compose yml, where all the configuration is done. Now that I've skipped the docker bit, how do i config my camera on frigate? From reading the frigate website, i need access to config file. I also need to tell frigate to save all streaming on my Truenas that I've shared with Proxmox via a NFS share. Anyone have a similar setup? These LXC containers seem pretty cool as concept, as from what I understand, they're similar to a bare metal install except the host shares its kernel and they bring the convienence of containerisation. Basically, LXC and Docker are similar in concept but with Docker you have the benefit of compose and portainer which are universal whereas LXC is part of Proxmox. Is that a fair summary?
