How to

Customization

If you want, you can customize some options on your Minecraft Server. To do it, you need to edit ./ansible/playbook.yml minecraft-server role.

  • server_jar_url: The server.jar file that will run the server. The version of this file must match the version of the Minecraft Client. (Default 1.20.1)

The other variables are self-explainable.

Provision and Configure

  1. Init terraform:
cd terraform/<aws | hetzner> && terraform init
  1. Create, if not existent, an SSH key:
ssh-keygen

  1. Config your credentials on ./env/.env.<aws | hetzner>

  2. Provision your server:

./provision.sh <aws | hetzner>

Just Configure

If you already have a server, you can only run the ansible playbook that install and configure a Minecraft Server on your server.

  1. Write the user that ansible will user and your IP address on ./ansible/hosts.ini

  2. Install ansible community.general collection:

ansible-galaxy collection install community.general
  1. Run:
cd ansible && ansible-playbook -i hosts.ini -v playbook.yml

Destroy

If you want to destroy your Minecraft Server instances, just run:

./destroy.sh <aws | hetzner>

Playing

  • Grab your server IP address (output.json)
  • Go to Multiplayer on your Minecraft Client
  • Add your brand new server and start playing!

Managing

  1. SSH into your server:
ssh minecraft@<server ip address>
  1. Your Minecraft Server simply is a systemd process, that you can manage with:
sudo /bin/systemctl (status | start | stop | restart | enable | disable)
