Introduction

Welcome to part 3 of the Talos Linux Kubernetes cluster bootstrap of the Proxmox series. In today's post, we will perform changes to make the code reusable and extensible. Users can follow a GitOps approach towards Talos deployments.

We assume you already have the basic project structure. To follow along, check out the part 1 and part 2 posts.

Introduction

In Part 1 of the series, we showed how to install Sveltos on a Kubernetes management cluster. We also deployed Kyverno. After that, we used sveltosctl, the Sveltos Dashboard, and the Grafana Dashboard for observability. In today's post, we will take the next step and talk about the Dry-run feature, how to express a Sveltos ClusterProfile as a template and what the latest templateResourceRefs are.

Introduction

It is already a year since I started getting more involved with ProjectSveltos. Over the past few months, a lot of work was put into making Sveltos not only more intuitive but also easier to use, all while preserving its core features and functionality.

This post will be split into two parts, with both sections covering the latest updates along with simple deployment examples to help you get started. So, let's dive into the world of Sveltos and explore what's new!

Introduction

Welcome to part 2 of the Talos Linux Kubernetes cluster bootstrap on the Proxmox series.

We will enable Cilium as our CNI (Container Network Interface), use KubeProxy replacement, and set up Cilium Hubble for network observability. We will outline basic kubectl commands to evaluate the Cilium setup alongside network tests.

We assume you already have the basic project structurefrom part 1, as we will extend the configuration for Cilium. To follow along, check out the part 1 post.

Talos, Proxmox, OpenTofu: Beginner's Guide Pt.1

Introduction

I have been bootstrapping RKE2 and K3s clusters for a while now. I work on different platforms, both on-prem and in the cloud. This includes VMware, Proxmox, Nutanix, and almost every major cloud provider. This week, I have decided to take a different approach and discover something new! Bootstrap a Talos Kubernetes cluster on Proxmox using OpenTofu as the Infrastructure as Code (IaC) solution. My first interaction with Talos Linux was a couple of months back when Justin Garrison posted something about the ease of Kubernetes cluster deployment. I did not have much time back then, but here we come!

The blog post will be split into two parts. Part 1 will include a basic deployment of a Talos cluster using the out-of-the-box configuration, while Part 2 will contain the required configuration changes to use Cilium as our CNI. Get ready to roll up your sleeves and dive into the essentials of Talos Linux with OpenTofu on Proxmox.

Introduction

Migration alert! For a while, I wanted to move my Docusaurus blog to a new custom domain. In the beginning, it appeared to be an overwhelming task due to time constraints and, of course, DNS! Nonetheless, after some research, I finally managed to make the migration smooth and hassle-free. This blog post is meant to save you time and frustration if you are looking to deploy a Docusaurus site on GitHub Pages with your custom domain without running into DNS problems along the way!

Funny Fact: After spending the last couple of days troubleshooting DNS issues (fun, right?), a colleague and good friend, Justus, surprised me with this awesome T-shirt! 😂

Now, let's dive into the configuration! 👇
