My kubernetes infrastructure built in public

This repository contains my personal Kubernetes cluster setup (on hetzner), and is highly opinionated.

Goal

Make it as easy as possible to deploy to your own Kubernetes cluster.
All infrastructure is written in this Git folder, should be easy to migrate to a new server.
Have a self sustained CI/CD with secrets system.
Metrics, Logs, BI should work out of the box.
goteleport act as your jump point.

build in public
no vendor lock in
be able to move to other providers or self host
