Cluster

[Updated] Updting this for 2025, including Noble as the image (24.04) and adding some other missing bits..

I needed to create a few Ubuntu VMs for a Kubernetes cluster for testing, and I wanted to make the process as simple as possible using Proxmox and some minimal automation. Here’s what I’ve done:

First, Download the base image:

wget https://cloud-images.ubuntu.com/noble/current/noble-server-cloudimg-amd64.img

To be able to run the commands below, you need to install libguestfs-tools on proxmox. An apt-update and apt install libguestfs-tools is all that is needed.

Well, day 9 of #100daysofhomelab is about Disaster Recovery… Well, at least the disaster part… Recovery not so much… My Kubernetes cluster, how do I put this… shat the bed… It’s been up and down all day and then the Longhorn storage failed and took my WordPress install with it… I lost yesterday’s post (which isn’t the end of the world) but it’s a pain in the ass… I ended up using the old docker copy of WordPress, so at least that’s online.

Day 7 of #100daysofhomelab and just a quick update for today: this site is now running on my Kubernetes Cluster! I am using Cloudflare tunnels for the ingress controller (more on that later) and so far, so good… Most of this was done yesterday, and it was a swap over of the DNS stuff today… been sick most of the day, so that’s all I got in me for day 7…

I now think this WordPress instance is hosted on Kubernetes and is also being shared over CloudflareD running inside Kubernetes! If this shows on my main site, it works! If not, I have broken something…

[UPDATE] Yup! It’s working! 🙂

Day 6 of #100daysofhomelab and I have some progress on my Kubernetes cluster!

Then after a few min, it comes back online…

Also, I got WordPress installed in Kubernetes! Now to migrate this blog over… Hopefully before my next update tomorrow…

Day 5 of #100daysofhomelab and its mostly reading… the daddy was in the hospital for the last 2 weeks, including over Christmas day, so tomorrow is Christmas day for us… Turkey, ham and all the usual stuff… So, been busy with that. But have been reading a couple of docs, so some links for today:

That’s about it for today… I’ll be back tomorrow… hopefully…

Day 3 of #100daysofhomelab and more Kubernetes messing today. Haven’t got it working, but messing with it is a start. Some links and notes are below:

I am planning on moving my WordPress install over from my Docker host to Kubernetes in the next few days, so running through the docks from Bharathiraja above, but I keep getting errors related to MySQL… More digging is required. I use Cloudflare Tunnels to secure my WordPress install, so the docs on how to use Cloudflare Tunnels with Kubernetes are important…

Day 2 of #100daysofhomelab and more messing with Kubernetes… So far, I have built, torn down, rebuilt and torn down a second time… and now building for a third time! Techno Tims Ansible scripts for the Win! A couple of notes for today:

More work on the cluster is required. This blog is hosted in-house on one of the docker instances… Hopefully, at some stage, it will be moved to the K3s cluster! That would be the first major move!

I have decided to start my #100daysofhomelab journey again, so today is day 1. I have been working on a K3s cluster in the house, and so far, I have to start again… going to rebuild it again tomorrow at some stage…

Lots of Links

some notes for myself:
