Kubernetes The Hard Way on DigitalOcean (Terraform)

Kubernetes The Hard Way on DigitalOcean (Terraform)

This repository contains Terraform configuration files to quickly provision the necessary DigitalOcean Droplets to complete the Kubernetes The Hard Way tutorial.

Infrastructure Overview

This setup creates 4 Droplets:

• jump-box: jumphost
• server: Control plane node
• node-1, node-0*: Worker nodes

This configuration mirrors the official tutorial's requirements and lets you focus on Kubernetes component configuration.

🚀 Getting Started

Prerequisites

• Terraform: Install Terraform on your local machine
• DigitalOcean Account & API Token: Generate a Personal Access Token with read/write permissions
• SSH Key Pair: Required for Droplet access

1. Configure Variables

Create a terraform.tfvars file in the root directory:

dotoken = "YOUR_DO_API_TOKEN_HERE"
ssh_pub_key = "~/.ssh/k8s_hard_way_rsa.pub"

Variable	Description	Example
dotoken	DigitalOcean Personal Access Token	"xxxxxxxxxxxx..."
ssh_pub_key	Path to your public SSH key	"~/.ssh/id_rsa.pub"

2. Initialize and Apply

Run the following commands in your terminal to initialize the provider and provision the infrastructure:

terraform init
terraform apply -var-file="variables.tfvars"  # Type 'yes' to confirm

💾 Outputs

After provisioning, retrieve the Droplet IP addresses:

terraform output

Outputs include:

jump_box = "XXX.XXX.XXX.XXX"
node-0 = "XXX.XXX.XXX.XXX"
node-1 = "XXX.XXX.XXX.XXX"
server = "XXX.XXX.XXX.XXX"

⚠️ Cleanup

To destroy resources and avoid billing:

terraform destroy -var-file="variables.tfvars  # Type 'yes' to confirm
