Similar except for a few minor details. I have jackett in the stack too. I have wireguard instead of tailscale. Debian on the host. No zfs, just a bunch of disks. The whole torrent stack is on the vpn so metadata requests don’t go out via my ip. I limit the vpn countries to non 14 eyes countries. I change the vpn country every time the vpn container comes up. I use vuetorrent as the qbittorrent webui.
I’d try each application one by one. Maybe write a script to monitor load and stop the program if it goes past your desired threshold and notify you.
It could also be a setting in some app like photoprism or immich … I think one of them uses tensorflow to classify images. That would increase the load if thats running in the background.
Maybe try them with an empty directory so there is no data to process and see if you encounter the error. Then add some data and see how the load is.
If I was going to do it I would only host the site on tor or i2p. I’d only host magnet links with minimal metadata and aim to have the site work without JavaScript. Maybe a small flask application or something to populate the pages using templates. Very basic, light weight and secure.
I would also release a monthly dump of the site to allow it to survive in the event of a takedown .
This way you have a minimal attack surface , you are protected from legal threats as they dont know where or who is hosting and they dont have a hosting provider to send the notices to.
With regular dumps of the site , taking it down becomes futile as there are copies out there in the wild, that can spring up the next day if needed. Its like a diversified seed bank if you will 😉.
