Knowing what and when to abstract can be hard to define precisely. Over abstraction has a cost. So does under abstraction. I have seen, writen and refactored terrible examples of both. Anecdotally, flattening an over abstracted hierarchy feels like less work and usually has better test coverage to validate correctness after refactoring than abstracting under abstracted code (spaghetti code, linear code, brand it how you will). Be aware of both extremes and try to find the balance.
My homelab is a 2 node Kubernetes cluster (k3s, raspberry pis), going to scale it up to 4 nodes some day when I want a weekend project.
Built it to learn Kubernetes while studying for CKA/CKD certification for work where I design, implement and maintain service architectures running in Kubernetes/Openshift environments every day. It’s relatively easy for me to manage Kubernetes for my home lab, but It’s a bit heavy and has a steep learning curve if you are new to it which (understandably) puts people off it I think. Especially for homelab/selfhosting use cases. It’s a very valuable (literally $$$) skill if you are in that enterprise space though.
Switched to qbittorrent+gluetun side car recently and it’s been pretty good compared to the poorly maintained combo torrent+OpenVPN images I was using. Being able to update my torrent client image/config independent from the VPN client is great. Unfortunately most of the docs are Docker focused so it’s a bit of trial and error to get it setup in a non-docker environment like Kubernetes. Here’s my deployment in case it’s useful for anyone. Be careful that you configure qbittirrent to use “tun0” as it’s network interface or you will be exposed (got pinged by AT&T before I realized that one). I’m sure there’s a more robust way to makeuse of gluetun’s DNS over TLS and iptables kill switch that doesn’t require messing with qbittorrent config to secure, but that’s what I have so far and it works well enough for now.
Look for refurbished units, you can get enterprise grade units for like half the retail price. I recently got a refurbished APC from refurbups.com. Comes with brand new batteries, mostly rack mountable stuff. Ended up being a little over half the price of a brand new one with shipping. Can’t tell at a glance if they ship to Canada, but if not I’d be surprised if there wasn’t a similar Canada based site you could find.

There’s one for sonarr too.
Rpi simply cannot handle live transcoding because it’s a computationally expensive process. Audio and video codec support is a confusing landscape. Some of it is hardware support, some software support, sometimes there are weird licensing quirks… I replaced my Chromecast with an Nvidia Shield and it mostly eliminated transcodes, though i still sometimes encounter issues. For maximum compatibility look for files that are MP4, x264 (or h264) and AAC.
Got a refurbished APC coming in today. Looking forward to not having to worry about my NAS drives or losing internet because or a split second power blip.
Not really, its mostly a hobby/nerdy/because I can thing. I am a software engineer with a decade of experience. The job sometimes requires virtual sys admin work (VM/container, cloud networking, etc). Setting up my own baremetal cluster has given me more insight into how things work, especially on the network side. Most of my peers take for granted that traffic gets in or out of a cluster, but I can actually troubleshoot it or design with it in mind.
I considered it but RAM is very limited on the NAS and the cluster nodes, it’s my primary bottleneck. it would also be more volitile. the two SSDs are RAID 1 redundant, just like the underlying HDDs, in addition to the built in power loss protection on the drives. RAM discs are great if you can spare them and have a UPS though.
