K3s Cluster Setup with Terraform

This Terraform configuration sets up a k3s cluster on an existing virtual machine.

Prerequisites

• Terraform installed on your local machine
• SSH access to the target machine
• SSH private key configured

Usage

1. Initialize Terraform:

terraform init

2. Apply the configuration:

terraform apply

3. To destroy the cluster:

terraform destroy

Configuration

The main configuration is in main.tf. It uses the SSH provider to:

1. Install k3s on the target machine
2. Retrieve the node token
3. Verify the node is running

Important Notes

• Make sure your SSH private key has the correct permissions (600)
• The k3s token will be output after successful installation
• You can access the cluster using kubectl after copying the kubeconfig from the server
