Adjustments to Proxmox Since my original post I have turned my single Proxmox node into a Proxmox cluster, added some shared storage and created a cloudinit template. With all of that in place I’m now going…

Previously my “personal update” posts discussed how I was undertaking an apprenticeship. That was a Bachelor of Science (BSc) in Digital and Technology Solutions, with my specialism/pathway focusing on Software Engineering. The apprenticeship expanded my knowledge, gave me confidence and helped introduce me to new ways of researching/investigating technologies. I successfully…

Continue reading →: Proxmox: Cloudinit
In this blog post I am going to look at creating a virtual machine (VM) template that has cloudinit so that some settings are automatically configured at launch of any VMs built from the template. The first step towards a cloudinit template is finding a cloudinit image. Ubuntu Cloudinit Images…

We are currently in an Artificial Intelligence (AI) summer, with new AI solutions and AI features appearing in various technologies. The popularity and usage of AI is growing which brings both positives (automation, new solutions) and negatives (ethical issues, bias). As I’m using AI in my professional role, and at…

Continue reading →: Proxmox Cluster
A Proxmox cluster allows for High Availability (requires 3 nodes) and resource sharing. In a production data centre it would allow for Virtual Machines (VMs) or containers to move between nodes to help keep production systems running. It is not something I’ve done previously as I only had 1 device…
Hello,
Welcome to GeekTechStuff
