Terraform module to setup k3s cluster on Hetzner cloud
terraform-hcloud-k3s Terraform module to setup k3s cluster on Hetzner cloud Heavily inspired by: https://github.com/vitobotta/hetzner-k3s Thanks a lot! Prerequisites - generate a ssh keypair (id_ssh) and place it in the root directory of your terraform - ssh-keygen -f ./id_ssh Resources created in Hetzner Cloud - Main nodes (controlplane) like defined in main_pool_config - Woker nodes like defined in worker_pool_config - Private network & subnet - Loadblancer for kubernetes API access - Firewall for all nodes Installed inside Cluster - Hetzner CSI - https://github.com/hetznercloud/csi-driver - Hetzner CCM - https://github.com/hetznercloud/hcloud-cloud-controller-manager - K3S Rancher System Upgrade Controller - https://rancher.com/docs/k3s/latest/en/upgrades/automated/ Remarks - Nodes use
