# Infrastructure configuration
- Clone this repo
- Edit ```vars/infra.yml``` as prefered
```bash
---
# VMs hostnames (FQDN) - Example: pier.terrapin.ch
master_server: master.juna
worker_node_1: worker1.juna
worker_node_2: worker2.juna
# IP addreses
master_server_ip: "10.0.1.10"
worker_node_1_ip: "10.0.1.20"
worker_node_2_ip: "10.0.1.30"
# Disk sizes

# OS - Ubuntu 24.04
vagrant_box: "bento/ubuntu-24.04"
# VirtualBox for Ubuntu 22.04 - https://www.virtualbox.org/wiki/Linux_Downloads
# Will be installed on the host that launches the playbooks (localhost by default)
vbox_ubuntu: "https://download.virtualbox.org/virtualbox/7.0.20/virtualbox-7.0_7.0.20-163906~Ubuntu~noble_amd64.deb"
```
# Windows considerations
- Install on your windows machine: [Vagrant](https://developer.hashicorp.com/vagrant/downloads), [VirtualBox](https://www.virtualbox.org/wiki/Downloads) & [WSL2](https://docs.microsoft.com/en-us/windows/wsl/install)
- Create Ubuntu distribution: `wsl --install -d ubuntu`
- Convert distribution to use WSL2: `wsl --set-version ubuntu 2`
- Enter the machine `wsl -d Ubuntu`
- Install Ansible `python3 -m pip install ansible`
# Launch
## Windows
**Inside WSL**
```bash
ansible-playbook deploy_infra_windows.yml
```
**Outside WSL**
```bash
vagrant up
```
**Inside WSL - After vagrant up finishes**
```bash
ansible-playbook setup_k3s.yml
```
## Linux
```bash
ansible-playbook deploy_infra.yml
```
```bash
ansible-playbook setup_k3s.yml
```
# Kubeconfig
Your kubeconfig file will be in ~/.kube/k3s.yaml to use it you can set the **KUBECONFIG** environment variable with this command
```bash
export KUBECONFIG="~/.kube/k3s.yaml"
```
Verify you have access to the cluster
```bash
kubectl get nodes
```
And you're all set
