AJ's Blog
This is a personal blog focused on computer software and hardware. Most
projects are implementing software and hardware for a homelab. What is a
homelab? I would say a homelab could be a single computer or dozens of
computers connected in a network. You can also integrate with computers
in the Cloud.

A GPU can be used to run applications that leverage machine learning models as well as the name suggests, graphics applications. In the homelab I will use a GPU to run AI models, transcode media files, and any other application that can leverage GPU hardware acceleration.
Using a GPU in a Kubernetes cluster involves setting up the cluster to recognize and allocate GPU resources to pods that require them.
Prerequisites First of all, you need a Kubernetes cluster and a computer with a Nvidia GPU that is also joined to the Kubernetes cluster.

The openEBS project is simplified, easy to deploy and upgrade, open source, persistent block storage on the Kubernetes platform. If you are not familiar with Kubernetes (k8s), check out a previous post to get started. If you are using Kubernetes in a homelab which is what I focus on in this blog, you may notice that setting up apps that worked well in Docker are much more challenging in Kubernetes. It is very easy to set up static web apps in Kubernetes as the container image includes all the files you need.

As the foundation of my homelab takes shape, I’m ready to dive into the world of container orchestration with Kubernetes. In this blog post, I’ll outline my experience deploying software applications using Kubernetes, leveraging open-source projects to manage and access software running in the cluster.
Prerequisites Network Before deploying any software, I recommend having a Network setup so that computers can communicate with themselves and systems over the Internet. All Kubernetes related computers need to be connected to the same network.

Upgrading your Raspberry Pi’s operating system can be a breeze, and with Raspbian Bookworm being the latest and greatest version available, it’s definitely worth considering. To start, make sure you have a stable internet connection and a compatible Raspberry Pi running Raspbian Bullseye. I will be upgrading my Raspberry Pi 3 that serves as my primary DNS server.
Before the upgrade Before running any upgrade operations, make sure your Pi system is up to date.

Large language models are artificial intelligence systems that use complex algorithms to process and analyze vast amounts of text data, allowing them to learn patterns, relationships, and context within language. These models typically consist of multiple layers of interconnected neural networks that are trained on massive datasets of text, often exceeding tens or even hundreds of millions of examples. As the model processes and learns from this input, it develops an ability to generate coherent and natural-sounding text, respond to prompts and questions, and even engage in creative tasks like writing stories or composing music.

Caddy_logo I will be using Caddy to serve as a reverse proxy for my network. With Caddy, I can manage my proxy configurations in a single file. Caddy is an easy to configure web server and can also function as a reverse proxy. Caddy is free and open-source software.
On a system where I want to securely expose services running on containers, Caddy is easy for me to pick a certificate and then define all of the proxy rules for each container in a single file.
