Inception-of-Things (IoT)

Summary

This document serves as a System Administration exercise focused on Kubernetes (K3s and K3d) and Vagrant. Participants will gain hands-on experience setting up virtual machines, deploying applications, and using container orchestration tools.

Preamble

This project is a minimal introduction to Kubernetes, designed to deepen understanding through practical exercises using K3s, K3d, and Vagrant.

Introduction

The project aims to:

• Set up a personal virtual machine with Vagrant and a chosen distribution.
• Implement Kubernetes using K3s and K3d.
• Deploy applications using Kubernetes.

Mandatory Part

Part 1: K3s and Vagrant

• Set up two virtual machines with Vagrant.
• Install K3s on both machines, configuring one as a controller and the other as an agent.

Part 2: K3s and Three Simple Applications

• Deploy three web applications on a single virtual machine using K3s.
• Implement routing based on the HOST header to display different applications.

Part 3: K3d and Argo CD

• Install K3d and Docker.
• Create two namespaces: one for Argo CD and another for a development application.
• Deploy an application using Argo CD from a public GitHub repository.
