After setting up my lab environment in the previous article, I’ve now also set up the Kubernetes cluster itself, with kubeadm as the setup tool and Cilium as the CNI plugin for networking. Here, I will describe why I chose the tools I did, and how I initialized the cluster, as well as how to remove the cluster when necessary. Tools choice Before setting up a cluster, several choices need to be made....
So, as I mentioned in my last article, I want to give Kubernetes another try after HashiCorp’s recent license change. This also gives me a chance to put the lab back in Homelab, as it has mostly been a Homeprod environment - not much experimentation going on there, just slow, intentional incremental changes here and there. But my Homeprod env is not really suited for housing a Kubernetes cluster. It mostly consists of Raspberry Pis....
Basically my entire Homelab is build upon HashiCorp’s products. On August 10th, HashiCorp announced that they would switch all of their products to the BSL, the Business Source License, where they had been licensed under the Mozilla Public License before. From my (rather rudimentary!) understanding, the license basically says that all “non-production” use is perfectly fine. I’m pretty confident that that covers all of my own personal usage. But as it was pointed out to me today, that formulation also creates a lot of uncertainty for commercial entities of all kinds....
I started my Fediverse journey a little over a year ago, with my account creation date being August 3rd, 2022. I was initially drawn to the Fediverse due to the simple fact that this was social media I could host myself. Neat, right? And I want to reflect a little bit on how it’s going. So let’s start with my social media usage in the past, so you can properly classify where the following comments are coming from....
I’ve long been wondering how much power my Homelab consumes, especially with my switch from a single relatively beefy server to a gaggle of Raspberry Pis. In the end, I put in three smart plugs supporting MQTT. I would have loved to have per-machine power consumption stats, but I didn’t want to invest that much money into smart plugs. To wet your appetite a bit, here is a snapshot of the resulting Grafana dashboard:...
