Can you teach me how to use kubernetes, using k3s, perhaps on virtual machines in my home? starting with beginner projects?Share Prompt
Absolutely! Using Kubernetes with k3s is a great way to get started with container orchestration in a lightweight manner. k3s is a lightweight Kubernetes distribution that is easy to install and is ideal for development and testing environments. Here’s a step-by-step guide to help you get started with Kubernetes using k3s on virtual machines (VMs) at home.

### Prerequisites

1. **Virtual Machines**: Set up at least one VM (but ideally two or more) to run your k3s cluster. You can use virtualization software like VirtualBox, VMware, or any cloud provider.
2. **Operating System**: A lightweight Linux distribution (Ubuntu, CentOS, etc.) is recommended.
3. **Basic Command Line Knowledge**: Familiarity with the terminal and basic Linux commands.
4. **Docker**: Make sure Docker is installed on the VMs. k3s requires Docker to run.

### Step 1: Setting Up Your Virtual Machines

1. **Install a Linux Distribution**: Set up your VMs with a compatible Linux distribution. Ubuntu 20.04 LTS is a good choice.

2. **Update Your System**:
   ```bash
   sudo apt update && sudo apt upgrade -y
   ```

3. **Install Docker**:
   ```bash
   sudo apt install -y docker.io
   sudo systemctl start docker
   sudo systemctl enable docker
   ```

 Sure, I'd be happy to help you get started with Kubernetes using k3s on virtual machines in your home! Here's a step-by-step guide to get you up and running:

**Step 1: Install VirtualBox**

VirtualBox is a popular virtualization platform that allows you to create and run virtual machines on your local computer. You can download VirtualBox for free from the official website: <https://www.virtualbox.org/wiki/Downloads>

**Step 2: Create Virtual Machines**

Once you have VirtualBox installed, you can create a few virtual machines to use as Kubernetes nodes. Here are the minimum requirements for each node:

* 1 vCPU
* 512 MB RAM
* 20 GB disk space

You can create the virtual machines with your preferred operating system, such as Ubuntu or CentOS. Make sure to enable virtualization in the BIOS settings of your host machine.

**Step 3: Install k3s on the Master Node**

Once you have created the virtual machines, you can install k3s on the master node. You can download the k3s installation script from the official website: <https://rancher.com/docs/k3s/latest/en/installation/>

Run the following command on the master node to install k3
