Build base image

We need to extend the Talos base image with open-iscsi which we do via a GitHub action triggered manually. This will no longer be necessary with Longhorn 1.6 longhorn/longhorn#3161

Generate Hetzner Cloud snapshot for Talos image

Based on the guide from Talos: https://github.com/siderolabs/talos

export HCLOUD_TOKEN=TOKEN_WITH_READ_WRITE_PERMISSIONS
cd talos
packer init .
packer build .

You may need to update the version of Talos in the Terraform

Create cluster

Create the file control-plane/secrets.auto.tfvars and put in hetzner_token=TOKEN_WITH_READ_WRITE_PERMISSIONS

cd neptune
terraform init
terraform apply

After creation, you can get the configuration for Talos via terraform output -raw talosconfig > talosconfig and the Kubernetes config via terraform output -raw kubeconfig > kubeconfig. Place the kubeconfig in ~/.kube/config (by default on Linux) or point the KUBECONFIG env to the file.
