So I recently acquired three raspberry pi 3B’s. I want to get into
hosting my own services as I’ve been looking at home labing for quite
some time out of curiosity and a piece of entertainment, but I never
had a moment to jump in. Now having three sad pi’s doing no work in my
drawer all day I felt like this was the time to start. I want to
deploy services onto them like pi-hole, pi-VPN, home assistant, et
cetera, ... Just light weight services to get my toes wet.

I looked into my options and I thought that clustering them together
made the most sense. This way, there is redundancy if something ever
were to happen to one, scalability if I were to acquire more pi’s, and
distributing of resources, and ease of management since there is only
one node to talk to. The only problem is that when reading into
kubernetes and watching video’s on how other people do it I feel kinda
overwhelmed, and it looks so complicated.

It’s not that I’m new to linux, the command line, or deploying
containers. Not to say I’ve got all the required skills. Subnetting,
and all else network wise is still very new and abstract to me (if
anyone has some great guids for noobs lmk, it’d be appricated, none of
what I watched seems to have clicked). But for some reason it just
looks way to hard to do. And I can barely understand what the guide is
doing.

Am I forgetting an easier way, am I just overcomplicating things,
because that is what it feels like. Or am I just affraid to jump in
for real?

Why do you want to go from zero straight to clustering with
kubernetes?

Why not simply start with running services on a single Pi first?

And if you do want to start with clusters, considering the low
performance of a Raspi 3B, you should probably look at using
lightweight k3s instead of fullblown k8s.

Tons of tutorials about how to get started with k3s or k8s exist
already, there is no need to write another one.

Thank you that is very constuctive.

I was gonna run all things bare metal, but the build in load
balancing, and using all the resources sounded really cool. This way
there is one machine to talk to, and all the resources needly managed.
But it probably couldn’t hurt to run bare metal first. I’ll definitely
check out r/HomeNetworking. There definitely some advice in there I
can use.

Thank you
