I’m running something surprisingly close to most of what you’re asking for sans the immich which I’m waiting on stability from them first. That warning at the time of their site that says it’s under constant development and not to use it as your primary picture store is a bit worrisome.
Unraid with 2 video cards
Plex Container (primary video card)
Plex VM (pass through secondary card handles DVR and backups and it’s also my steam remote provider)
Home assistant VM (running it in a VM is nicer than a container because of HAOS)
Jellyfin container
All the video services pull from the same catalog. I use jellyfin frequently but secondarily, it is my backup in case Plex heads in a direction I don’t like. They’ve already shown some indications I’m not going to like them in the future.
Deluge+VPN container
Cloudflare container (first set up is actually a pain in the ass)
Tailscale plugin
SearxNG container self-hosted search engine tool
Pi hole in a container
Pi hole on a raspberry pi
Plex gets accessed remotely via its own remote capabilities
Jellyfin gets accessed remotely via tailscale
SearXNG is access remotely via cloudflare
I have a secondary Plex server sitting on a raspberry pi with the backup pi hole
I am preparing to set up a peertube. Haven’t had a lot of luck with the container on unraid. I run a fair amount of proxmox at work so I’ll probably just use proxmox for it.
I run a separate dedicated system completely for my cameras. Not running frigate yet but I’ll get around to it eventually using blue iris at the moment.
My unraid gets as much uptime as updates allow. I love being able to just jbod my media discs together and still have some protection with parity.
I find the containerized version of Plex to be more stable than my VM version but that’s probably my own fault as I’m oversubscribing the vm.
