Minecraft server provisioning

This repository contains Terraform and Ansible scripts for provisioning a minecraft server with a FTB modpack into Hetzner cloud with AWS route 53 dns

The main infrastructure is first spun up by Terraform:

• One server of chosen type (cx11, cx21 etc.)
• A floating IP assigned to the server
• Subdomain A record pointing to the floating IP

Then Ansible provisions:

• Docker
• ufw
• fail2ban
• Minecraft server with a FTB modpack

using the Hetzner cloud dynamic inventory plugin.

See variables.tf and group_vars/all.yml for currently easily modifiable variables regarding the server

• Ansible
• Hetzner cloud account and API key (https://docs.hetzner.cloud)

• Registered main domain in Route53 (https://docs.aws.amazon.com/Route53/latest/DeveloperGuide/domain-register.html)
• Working ssh key to be used with ansible and ssh:ing into the server (default used key is ~/.ssh/id_rsa.pub)
