I followed trash guides to set everything up blindly and my set up is working well. But, I feel like having jellyfin in the same docker compose as my “arr” services isn’t good. So, I’d be curious to see if I should split things up. I am even wondering if i should let portainer manage everything.
So your name resolving them over multiple networks. Seems like a headache. By exposed ports I mean the host only has the reverse proxy with a port mapping. All other conteiners have no port mapping.
You can just refer to them by the name you give it in the services block, it’s actually really simple. No port mappings at all.

From my experience this only works inside docker. The host can’t refer to the containers by name, it won’t resolve anything, although I have seen an image that maps container name in /etc/hosts to allow this
