This post aims to be an introduction to AWX - a tool from Ansible that aims to make using Ansible a little easier. AWX can be a complicated subject, and precious little exists on the wider web documenting how to use it, so I thought I'd help improve that a

I've now got a basic setup for deploying machines via Foreman in Proxmox, but it's a little click-intensive. What if I could create the machine in Foreman and it automatically created the machines in Proxmox? Enter foreman-fog-proxmox. Somewhat strangely named due to its origins, it adds Proxmox as a "compute

It's time to test out Foreman properly, and deploy a machine. PreparationNavigate to Hosts -> Provisioning Setup -> Operating Systems. Opening the Operating Systems panel in Foreman.We see there's already an operating system - Debian 11.3 - which was created/discovered because our host machine runs

In this post I'll be creating a subnet and attempting to setup a DHCP server / "DHCP Proxy" for Foreman to use. It'll exist on the same server as the Foreman host. In Foreman, I navigated to Infrastructure -> Subnets, then clicked Create Subnet. Creating our homeprod subnet.I chose

This'll be a quick one. I've recently bought a new machine from a friend - an Athlon 3000G, Fractal Design 302-based NAS. It has slots for 6x 3.5" hard drives, of which 3 came filled with 14TB drives. A white storage server, sitting next to a larger PC, with

I've joined Mastodon, apparently just before "the big announcement" (spoiler: Elon Musk buying Twitter). Nothing against Twitter! I'll still be there as @gnomethrower, but I'll also be on Mastodon via aus.social - you can find me on Mastodon as @gnomethrower@aus.social. This page serves as an explainer of

Hi there! Quick post about Ubuntu 22.04. I've been running Ubuntu Server on and off for many years now, and have a few Ubuntu 20.04 boxes lying around. I thought I'd "live dangerously" and upgrade them to the still-quite-young Ubuntu 22.04 "Jammy Jellyfish" (if you consider upgrading

Something I don't find myself saying often: time for a downgrade. I contacted the Technitium folks about my issues with DHCP, and they helped me debug things a bit further. It led to me installing my first fresh Ubuntu 22.04 machine, and setting up a new Technitium instance on

Today I attended a hack session for Perth Linux Users Group, focusing on AV setup and networking. Notes on things that have come up: Backing up avmaster (Node #1), backing up some old PLUG footage. Initially tried copying over powerline ethernet, then we proposed sneakernet in ther form of a

I've got a need (okay, more of a want) to be able to deploy various operating systems in my home lab easily without too much fuss, to be able to try out various operating systems and distributions and so on more easily and with less hand-holding. Having an easy way

Friday's shenanigans started innocently enough - "I'll just rip out the DHCP server and run my own, and completely restructure the subnets, and..." as it started, soon led to a rabbithole. Where the last post left off, my "simple" DHCP solution was not working. This, as it would turn out,

At some point recently I decided to migrate away from Ghost(Pro). I've been using the service without issue for a year - a year where I had precious little time or energy to focus on hosting a blog, maintaining any sort of permanent infrastructure, or indeed on blogging at

My "home lab" is really just my apartment's network, running in a single VLAN. I've considered splitting into multiple VLANs before, but haven't found a proper reason to do so just yet. Today I made a few major changes to my home network. Doing so right before a Friday seems

I'm going to take the opportunity to wipe the Kubernetes cluster, which I think might be worth doing regularly anyways to prove it can be done. Ideally everything difficult-to-create or "big" should be stored in MooseFS. I went through the same procedure as before to create a K3s cluster: Unfortunately

Having learned a bit about Kubernetes, Rancher and K3S, I've decided I don't like how I setup Rancher originally. I'd like to set it up on a single-node k3s installation, with dns-01 based TLS certificates, at rancher.windowpa.in, without exposing it to the outside world. There's precious little guidance

Having run into issues with RKE, I'm going to try K3s instead. Go back to create a cluster and click the slider to RKE2/K3s. Select K3s from the dropdown. Create the cluster, then provision machines as before (but note it's a different command): Click "insecure", then copy and paste

I deployed my first cluster and... it didn't quite work, because etcd couldn't bind to its port. Drat. Likely this is because I deployed Rancher to k8s-1, then attempted to deploy a cluster to k8s-1/2/3. So, let's try again, but with a new machine called k8s-deployer (10.1.

Now it's time to get Docker installed. There are plenty of ways to do this, but luckily Rancher provides a handy script that will install it in one line. Install Docker... wings@k8s-1:~$ curl https://releases.rancher.com/install-docker/20.10.sh | sh Add our current user to the docker
