What it should do

• Disable swap
• Configure kernel modules and parameters
• Install conteinerd
• Install kubelet, kubeadm, kubectl
• Install helm, cilium
• Initialize the cluster
• Install a CNI (Cilium)
• Join cluster
• Install Hetzner ingress and CSI

Usage

# cat .tfvars
# Update .tfvars if needed
terraform apply -tfvars=.tfvars
