homelab

Oh boy that’s a loaded question for me.

Started migrating my SPOF server setup with docker-compose, that hosts my media and home automation setup to a k3s 4 node cluster deployment, in order to get things to be mostly HA.

I have the k3s cluster setup with Cilium and it does L2 ARP broadcasts to make the control plane HA alongside a few other apps like Traefik and PiHole. I also have Vault setup to store all my secrets and cert-manager to generate letsEncrypt certificates for all my services.

The idea was to have all my media moved to an NFS and to use longhorn as a distributed storage for my configs and DBs. Unfortunately it turns out that longhorns performance is less than ideal, and my fallback of storing my DBs and configs temporarily on my old server acting as NFS also did not work extremely well, most likely because of a network bottleneck.

So for now I have the Pods running with local storage with the exception of a few things like PiHole and Vault that I definitely want to be HA. And I did a full DR simulation and know I can restore from backup and do a full data recovery from the cloud in about 3hrs (data restore). I’ll eventually tackle moving configs and DBs off local storage again but not sure when.

I now have my full set of media (plex and *arr) apps running on k8s. I’ll also be migrating the home automation stuff soon.

On a side note I’ve grown to hate Duplicati it’s extremely slow and 90% of the time just plain fails to restore files. I’ve ended up moving to Kopia which seems to be working ok but isn’t the most intuitive.

P.S. Please forgive the unorganized brain dump, it’s late and it was a long day.

I didn't see a brief description for this community, so please excuse me if I'm off topic.

Small victories: I set up my first containerized WordPress application with the whole nine yards. Object cache, DB, PHP, web server in separate containers connected together by a simple and readable compose file. The task was easy. What was hard was changing the way I think about running a server as this monolithic thing. True, it's all on one physical server in the end, but the changes in mindset are becoming more difficult for me as I get older. I had always hated Docker as this wasteful oxymoronic "serverless" thing, but then I saw how I could use it to control dev environments. From there I've started to understand when the tool makes sense. For the first time, I feel like I get it.

I moved from Maryland to Colorado this summer and left my homelab on Maryland after begging my dad to have it in his house temporarily. I'm getting a replacement system up and running in Colorado using my old gaming PC. I'm moving away from enterprise gear to cut down on noise, heat, and power usage, but I'm going to miss the insane amount of RAM, ECC RAM, and nice hotswap HDD cases.

This week I switched my home assistant system from a raspberry pi to a VM under proxmox, so I started turning that raspberry pi into a display for my kitchen. I'm playing around with MagicMirror, but it doesn't do everything that I want, and I'm more comfortable writing Python than JavaScript, so I think I'm going to make a home assistant dashboard instead (I'll definitely need to make some custom integrations).

I'm also going to make the display a remote rhasspy system for the rhasspy server I'm adding to home assistant now that it's not running on a pi. If I can get rhasspy working well, this will get me one step closer to degoogling my life. All that's left after that is trying to setup my own invidious instance or using yt-dlp to get YouTube videos into jellyfin, and switching to grapheneOS on my phone and sandboxing Google maps. I unfortunately still need Google Maps when I occasionally drive. OSM is great for biking and walking, but it's not there for driving yet.

My UPS just died :( so I’m trying to repair it. It start beeping like it’s overloaded even with no load attached. I’m suspecting an issue around the current transformer ADC.

Apart from that, I have a TuringPi 2 loaded with SOQuartz boards to start up, I was thinking of trying kubernetes (k0s) to have some resilience for the base infra (dns resolver, dns root zone for the home domain, metrics) but I need a couple of days to start…

Not so much server-based, but the experimental part of "lab" is well covered: I replaced my late-2013 27" iMac's internal HDD with an SSD. It's a really delicate procedure, as the display is glued to the chassis; it needs to be cut loose and very carefully removed (it's tempered glass), and then re-glued with special adhesive strips. But the performance gain is worth it. In addition, it also now runs Ventura, even with the nVIDIA card, thanks to OpenCore Legacy Patcher. Feels like a new machine now, and is perfectly adequate even for small video editing tasks with its 32 GB RAM.

I have been looking at a silly project, totally not needed properly not worth it…. Of taking an old Mac mini G4 and installing an old Ubuntu os on it, then running old game servers for maximum retro loading times and keeping it in a old computer for the same reason but I think choosing a powerpc is the mistake….

Otherwise I have set overseer and starting to migrate people to Jellyfin
