Lightning node and Nostr relay should ideally run on separate VMs. Raspberry Piis not sufficient hardware for it.
Discussion
W/lightning, totally agree should be separate. Bitcoin, depends on need of the server.
I agree they should be kept separate. And I would personally keep them separate and not due to hardware/resource limits but because I simply donāt want anything else on my Bitcoin node. Iām concerned about my node becoming compromised. I initially thought it was okay but I changed my mind after presenting the idea to the Raspiblitz folks.
However, it is still the userās choice and some setups may provide sufficient isolation for some.
It depends on the users needs, but a Pi is absolutely sufficient enough for a private relay to store your own notes and events. I wouldn't co-mingle the two services though, for security purposes.
Is there a video or something how to set up ?
I don't know, sorry. I setup my relay manually.
Ime,, pis usually die just from running docker; if I were to run my relay in a pi Iād do it straight on the metal and skip docker altogether.
Would the hw in a pi allow for a private relay on top of ie umbrel (that is running full node and lightning)?
yes, it would. though, i wouldn't recommend it. i don't like mixing bitcoin with other applications for security purposes.
So umbrel app store is a bad take on the personal server set up?
Its really practical though.
Itās really practical, sure, but they have many applications that are resource dependent and/or is far too security compromising to really recommend past your first/initial node, learning about how these systems work.
