# k0sctl playground

This project aim to be a playground for [`k0sctl`](https://github.com/k0sproject/k0sctl),
some VMs are provisionned with [vagrant](https://www.vagrantup.com/) to be able
to be used with [`k0sctl`](https://github.com/k0sproject/k0sctl).

## Requirement

- [`rtx`](https://github.com/jdx/rtx)
- [`vagrant`](https://www.vagrantup.com/)

## Getting started

First you must boot VMs:

```bash
$ vagrant up
Bringing machine 'cluster-001' up with 'virtualbox' provider...
Bringing machine 'cluster-002' up with 'virtualbox' provider...
==> cluster-001: Importing base box 'bento/ubuntu-22.04'...
==> cluster-001: Matching MAC address for NAT networking...
==> cluster-001: Checking if box 'bento/ubuntu-22.04' version '202303.13.0' is up to date...
==> cluster-001: Setting the name of the VM: cluster-001
==> cluster-001: Clearing any previously set network interfaces...
==> cluster-001: Preparing network interfaces based on configuration...
cluster-001: Adapter 1: nat
cluster-001: Adapter 2: hostonly
==> cluster-001: Forwarding ports...
cluster-001: 22 (guest) => 2222 (host) (adapter 1)
==> cluster-001: Running 'pre-boot' VM customizations...
==> cluster-001: Booting VM...
...
```

Then you can now apply [`k0sctl configuration`](./multiple_controller_worker_nodes.yaml):

```bash
$ k0sctl apply --config ./k0sctl/multiple_controller_worker_nodes.yaml

INFO k0s cluster version v1.27.4+k0s.0 is now installed
INFO Tip: To access the cluster you can now fetch the admin kubeconfig using:
INFO k0sctl kubeconfig
```

You now have two clusters on two differents nodes. You can go on VMs to check:

```bash
$ vagrant ssh cluster-001

You can check, add or edit `k0sctl configurations` in [`k0sctl`](./k0sctl/).

## How to change VMs

You can edit the [`Vagrantfile`](./Vagrantfile) to update number of VMs or their
configurations.
