Hetzner Cloud Automatic Minecraft Server

This project provides a simplified way to deploy a public Minecraft server on Hetzner Cloud using Terraform/OpenTofu.

Prerequisites

Before you begin, ensure you have the following:

• OpenTofu: Download OpenTofu from https://opentofu.org/docs/intro/install/ and place the executable in the project directory or add it to your system's PATH.
• Hetzner Cloud Account: Create an account at https://accounts.hetzner.com/signUp.

Setup

1. Create a Hetzner Cloud Project: In the Hetzner Cloud UI, create a new project (e.g., "McServer").

2. Generate an API Token: Within the project, navigate to Security/API Tokens and create a new token named " OpenTofu" with read and write permissions.

3. Create terraform.tfvars: Create a file named terraform.tfvars in the project directory with the following content, replacing **YOUR GENERATED API TOKEN** with your actual token:

   hcloud_token = "**YOUR GENERATED API TOKEN**"

4. Generate SSH Key: Generate a new SSH key for server access:

   ssh-keygen -f mckey

5. Import DNS Zone (Optional): If you want to manage DNS records, import your Hetzner DNS zone using OpenTofu. Navigate to https://dns.hetzner.com/, select the zone you want to control, and import it using a command like this ( replace zone1 and the URL fragment with your zone's information):

   tofu import hetznerdns_zone.zone1 #id-from-url#

6. Initialize Terraform: Initialize the Terraform configuration:

   tofu init

7. Apply Configuration: Deploy the Minecraft server:

   tofu apply

Accessing Your Server

To retrieve the server's IP address, use the following command: shell tofu state show hcloud_server.minecraft

Data Persistence

Minecraft server data is stored on a separate volume, ensuring that your world persists even if the server is shut down or deleted and recreated.
