This is the repository I use to version control my kubernetes clusters I deploy and maintain at home. I currently use Talos to provide a secure, minimal and immutable environment for Kubernetes. Previous iterations of this repository relied on Debian-based Operating Systems which can lead unwanted changes in the base system.
Thanks to onedr0p, there is the cluster template that allows you to easily get started with your own kubernetes cluster at home. You don't need to have multiple computers or a fancy setup to get one working.
If you're interested, you can also join the community Discord: Home Operations. Several people are involved daily and it makes for some interesting conversations.
This repository uses the following layout for Kubernetes.
๐ kubernetes
โโโ ๐ {cluster}
โโโ ๐ apps # Per-cluster application-specific configurations.
โโโ ๐ bootstrap # Flux & Talos configurations for setting up the cluster.
โโโ ๐ flux # Flux configuration, application repositories and more.
โโโ ๐ kubeconfig # Kubernetes Certificate
โโโ ๐ talosconfig # Talos CertificateWhile most of my infrastructure and workloads are self-hosted I do rely upon the cloud for certain key parts of my setup. This saves me from having to worry about two things. (1) Dealing with chicken/egg scenarios and (2) services I critically need whether my cluster is online or not.

UniFi released a new feature update with UniFi routers that allow you to create custom dns records to be served to the whole network. I wroteExternal DNS Unifi Webhook to allow External DNS to gather service and ingress hosts from my clusters and deploy the records without any extra local resolvers.
