Building a Debian 13 (Trixie) LXC Template for Proxmox Debian 13 (trixie) was released, but (at least as of 2025-08-12) there isn’t a LXC template available for it on proxmox. I wanted a Debian 13 LXC container, so I made a template of my own. Install tooling We’re going to use Debian Appliance Builder to create a Debian 13 LXC template.

I’m setting up a new Node-RED instance as part of moving Home Assistant out of docker and onto an HAOS VM. My requirements were: Run Node-RED in a separate VM so I can move it to other proxmox hosts if there is resource contention or I need to fail over Proper SSL certificate Easy access via my tailnet Pre-requisites To follow these instructions, you will need: ...

I recently replaced a 2019 Intel MacBook Pro with a M3 Macbook Air, so I decided to wipe the MBP and install proxmox on it. It wasn’t as straightforward as installing on non-Apple hardware, so I’m documenting what I had to do here. Note that this post only covers getting things working on a MacBook Pro - look at the many online tutorials for what you should do once your node is up and running. ...

I run PiHole for ad-blocking on my home network. I’m an SRE in my day job, so of course I’m not running a single instance of something as important as DNS. I also don’t want to have to update things like local DNS entries or blocklists in multiple places, that will cause weird and annoying inconsistencies in my DNS. Enter orbital-sync. ...

I ordered a second UPS because thanks to PeaNUT, I saw that my current UPS is only providing 20 minutes of uptime. Unfortunately, as of this post, PeaNUT will only read one UPS’ metrics from Network UPS Tools per PeaNUT instance, so I’m going to start scraping the metrics into Prometheus and displaying them with Grafana. Here’s how I did it. ...

I wanted nice graphs for the various metrics I collect in my homelab and from my Home Assistant server. Here’s how I installed Prometheus and Grafana in my homelab to get them. ...

Set up nut-upsd and peanut in your homelab I run my Synology server and network switches off a UPS. I decided I wanted a dashboard for the UPS, here’s how I did set up Network UPS Tools, aka NUT, and the PeaNUT dashboard. ...

Last Tuesday night, my USG Pro died. I got it secondhand and I got almost five years use out of it, so it was past time for a more performant replacement. ...
