TIL: How to Use Tailscale to Connect to K3S PI Cluster So what do we do if want to connect to our K3S cluster running our RPIs, but we are not on the same network/at home. Well we can look to use a VPN, in this article we will be using tailscale. It is super easy to setup on NixOS, and we need very little config for Tailscale. It also has a generous free tier, which will be more than enough for our home lab use case. ...
In this post, we will go over how we can deploy K3S on our PI cluster we have set up. Which is running NixOS, and we can also pass secrets using sops nix based on the previous parts of this series. Some of you maybe wondering what is K3S, it is a Kubernetes distribution which is tiny i.e. the binary is only 50 MB. It also has fewer dependencies. Make it perfect our PI cluster and home lab and IoT apps. ...
TIL: How to Use Sops Nix With Colmena If we are using colmena, how can we set it up when we deploy a secret, for example when deploying k3s the token? i.e. services.k3s.tokenFile = "/my.token";. So to do this first, I will assume you already have a colmena config and sops-nix setup in your config. First, let’s set up our hosts, in this case RPIs which already come /etc/ssh/ssh_host_ed25519_key ssh key we can turn to an age key, i. ...
So in the previous article I showed you how I had set up my 4 RPI (Raspberry Pi) cluster and put NixOS on the machines. They are now connectable over SSH using just their hostnames, i.e. ssh [email protected]. Initially we deployed NixOS and a basic configuration to each of the RPIs manually. We want to automate this process rather than deploying to each machine manually. I looked at bento, but couldn’t quite work out how to make it work for my use case. ...
Background Recently, I proceeded to experiment with some Raspberry PIs (RPI) that I had lying around. I wanted to do something with them, so I decided I would turn them into a k8s cluster and put various random tools that might be nice to have on it. Such as a GitLab runner, Jellyfin media server & pi hole for ad blocking. Hardware The list below shows the things I used to set up my rpi cluster. ...
