i had arr in one stack and media in another.
Now in my kubernetes cluster everything is separated, but arr + torrent is in vpn and automatically uses the vpn-sidecar. And media (jellyfin + jellyseer) is separate.

I created them in the same compose but will probably split them up soon. There's no point in having them in the same file: *arr services and jacket interact with each other, but Jellyfin is its own thing and I often want/need to restart it alone. They're best as 2 separate stacks imo.

I have all of mine in their respective directories and have a master script that I run to bring them all up or take them down. Easier to exclude services from start up if I end up not needing them or something.

I group them by network.

Yes splitting them up is much better.

The only reason you should have secondary services there is if main service is using them exclusively.

Having a single compose file for multiple unrelated services sounds like a nightmare to stop, start and debug if one of your containers is acting weird.

Say for example you have something that needs a mysql server and you have no other use for it beyond that container, then it should go in there with the main seevice.

But then you eventually add another service which also needs a mysql backend. Do you add another mysql instance for that specific service? Or you could separate your existing one into its own compose file and just connect the two separate apps to the single instance.

Here's the way I have mine setup. https://github.com/DanTheMinotaur/HomeHost/tree/main/apps

I use an ansible job to deploy and run them.

I liked having them all in the same file - easier to keep everything in sync. I also had “dependency” links to keep things starting in order.

ive got 6 containers running from a single file no problem, some with weirdly attached volumes, some with ports some host-networked.

i actually added portainer After i had everything running. it was almost too easy.

just to add; im no expert, but i dont see any benefit to having their configs defined in separate files other than maybe portability.

Single hand-crafted artisan organic GMO-free compose file for services that egress through regional VPNs and are exposed internally through Tailscale; *arr, transmisson, piped, etc.

Plex, iSponsorBlock, ArchiveBox have their own compose files since I keep them close to upstream. This way when the inevitable breaks they're easier to troubleshoot.

Why separate it? It's part of the same stack. Radar downloads, Jellyfin plays.

A mix - my *arrs, Plex, etc run in my "media" stack's compose, but I have a handful of other stacks ("managing", "monitoring", "misc", "games", etc) for containers that aren't related.

This also helps keep networks separate so the containers are only talking to the ones I want them to

I used to try to run arr stack together, but separately from jellyfin and transmission because I use them not only with arr things

But now I'm using nixos, and having the same dilemma with .nix files

Same. Never felt the need to do them separately.

@AbsurdityAccelerator All one file. Makes reverse proxy easy and most don’t need any open ports. Probably somewhere around 40. Oh two in their separate files cause I compile them from source.

Use to do it individually. Now I do it all from one Master compose.

No Docker, because overhead and depending on a semi-closed ecosystem isn't cool. Also systemd is perfectly capable of providing all the security docker does by itself.
