A little over two years ago, I wrote a post on creating a Talos Linux cluster on AWS using Pulumi. At the time of that post, the Pulumi provider for Talos was still a prerelease version. Since then, the Talos provider has undergone some notable changes necessitating an update to the example code I have on GitHub. For your reading pleasure, therefore, I present you with the 2025 edition of a tutorial for using Pulumi to create a Talos Linux cluster on AWS.| Scott's Weblog
Recently I needed to be able to stand up a dual-stack (IPv4/IPv6) Kubernetes cluster on Flatcar Container Linux using kubeadm. At first glance, this seemed like it would be relatively straightforward, but as I dug deeper into it there were a few quirks that emerged. Given these quirks, it seemed like a worthwhile process to write up and publish here. In this post, you’ll see how to use Butane and kubeadm to bootstrap a dual-stack IPv4/IPv6 Kubernetes cluster on AWS.| Scott's Weblog
For those that aren’t aware, Talos Linux is a purpose-built Linux distribution designed for running Kubernetes. Bootstrapping a Talos Linux cluster is normally done via the Talos API, but this requires direct network access to the Talos Linux nodes. What happens if you don’t have direct network access to the nodes? In this post, I’ll share with you how to bootstrap a Talos Linux cluster over SSH.| Scott's Weblog
For folks using AWS in their day-to-day jobs, it comes as no secret that AWS’ Managed NAT Gateway—responsible for providing outbound Internet connectivity to otherwise private subnets—is an expensive proposition. While the primary concern for large organizations is the data processing fee, the concern for smaller organizations or folks like me who run a cloud-based lab instead of a hardware-based home lab is the per-hour cost. In this post, I’ll show you how to use Pulumi to use a NAT...| Scott's Weblog
In August 2023, Pulumi released a version of the Docker provider that supported SSH-based connections to a Docker daemon. I’ve written about using SSH with Docker before (see here), and I sometimes use AWS-based “Docker build hosts” with my M-series Macs to make it easier/simpler (and sometimes faster) to build x86_64-based Docker images. Naturally, I’m using an SSH connection in those cases. Until this past weekend, however, I hadn’t really made the time to look deeper into how to ...| Scott's Weblog
I’m a big fan of direnv, the tool that lets you load and unload environment variables depending on the current directory. It’s so very useful! Not too terribly long ago, I wanted to find a way to “dynamically activate” the Azure CLI using direnv. Basically, I wanted to be able to have the Azure CLI disabled (no configuration information) unless I was in a directory where I needed or wanted it to be active, and be able to make it active using direnv. I finally found a way to make it wo...| Scott's Weblog
