Project Description

A kubernetes controller that spins a dev k3s cluster within your existing kubernetes cluster, the idea is derived from k3d but instead of using docker on the desktop machine to spin a k3s cluster, I will be using kubernetes itself as the host for these clusters.

The user will have to create a Cluster Object which should look something like this:

apiVersion: k3k.io/v1alpha1
kind: Cluster
Spec:
  servers: 2
  agents: 3
  token: test
  version: v1.25.0-k3s1

Goal for this Hackweek

  • Create a POC for creating a cluster within a cluster
  • Create the base controller by either using kubebuilder or wrangler as the framework

      You might want to check out https://github.com/loft-sh/vcluster

      It does something different than what you propose (creates "virtual" k3s clusters with inside of a k8s cluster, all pods run in the host cluster separated via namespaces) - but it could serve the same purpose.

      @moio yeah I checked vcluster, they are doing great work with virtual clusters, however I think k3k could be different in a sense that it can be more dev-oriented by having full k3s cluster inside the namespace including workers nodes and networking, which something that vcluster doesnt do.

      and since the project is still in a very early state, please let me know if you have something in mind that can make this project different as well.

      I'd be curious to understand why the vcluster folks have structured the project the way they did - k3k's design idea seems much more natural to me. Please post about any of your findings!
