As of now Ingress NGINX is being retired, sad times all around. As per the blog post Ingress NGINX Retirement: What You Need to Know it mentions:

Existing deployments of Ingress NGINX will continue to function and installation artifacts will remain available.

But where would the fun be in that? Although I can tell you now, I should have left my setup the way it is... but nope, this is me migrating to the Gateway API. So let's get started!

I love trying out new text editors, don't ask me why because when I get used to one, something new comes out that I want to try—that's just the way it goes, I guess.

This time I am trying out Zed "The editor for what's next" written in Rust.

Zed is a next-generation code editor designed for high-performance collaboration with humans and AI.

I have been learning Go lately and wanted to try and expose a microservice using a Tailscale Funnel. I had a project inmind to build a small Go application that would build and deploy a Docker image to a private registry using a webhook. Therefore, I needed to figure out how to expose the application using Tailscale Funnel.

I love a bit of Kubernetes but I also hate it as I navigate the Kubernetes landscape and learning from doing. I have come across multiple gotyas. This is one of them, I run a CloudnativePG Cluster, Originally I only used this to play around with Postgres.

So it begins again... I have started rebuilding my homelab, but instead of going bare metal, I am moving to Proxmox mainly to reduce the number of physical machines as well as to experience working with a hypervisor. I have used Proxmox before, but this time I am going to try to get it as close to production-ready as I can.

Today I have set up HorizontalPodAutoscaler (HPA) on a basic level. What is HorizontalPodAutoscaler you ask! Well, HorizontalPodAutoscaler allows your application to well, scale...horizontally. HPA adjusts the number of pods running your app to match how much work needs to be done. In the words of ChatGPT here is the ELI5 version:

I have spent some time setting up my own instance of CloudnativePG inside my Kubernetes cluster. I have two instances a dev instance, and a "prod" instance. Normally I would use pg_dump to backup the databases, but I wanted to try something different.

If you deployed your Kubernetes cluster in Cloud, the cloud provider will take care of creating Load balancer instances. But if you are using bare metal for the Kubernetes cluster, you have very limited choices.

A little background here, at work we use Flux this has been set up for quite a while way before ArgoCD was released. So liking new and shiny things, I decided to go with ArgoCD plus I liked the logo much more.

I have always wanted to learn how to install and manage a Kubernetes cluster so this is how I have gone about it. After going through many tutorials, YT videos and even the Kubernetes official docs. I struggled to get a cluster up and running. The official docs just IMO seem all over the place.
