This terraform setup allows for easy provisioning of a preconfigured K3S cluster which aims to minimize the time to get started with a testing cluster. This cluster is obviously not production ready but just intended for testing and learning purposes.

In order to setup the cluster, you need:

• Hetzner Cloud Project with an API key (read/write)
• Terraform

Generate a file terraform.tfvars. You can find a template wihtin example.terraform.tfvars. Insert your API key here. Now run the following commands:

terraform init
terraform apply

By default, this provisions a CX21 instance on Hetzner with a preconfigured K3S cluster. To further configure the provisioned instance, check variables.tf to see the other Terraform variables that are being used within resources.tf. To gain access to the provisioned cluster, use the command terraform output to see commands to 1) connect to the provisioned instance using SSH or 2) copy the kubeconfig file to your host machine using SCP.
