controlplane = {
    count   = 1,
    type    = "cpx11"
    type_lb = ""
}

# regions to use
regions = ["nbg1", "fsn1", "hel1"]

# counts and type of worker nodes by redion
instances = {
    "nbg1" = {
      web_count            = 0,
      web_instance_type    = "cx11",
      worker_count         = 0,
      worker_instance_type = "cx11",
    },
    "fsn1" = {
      web_count            = 0,
      web_instance_type    = "cx11",
      worker_count         = 0,
      worker_instance_type = "cx11",
    }
    "hel1" = {
      web_count            = 1,
      web_instance_type    = "cx11",
      worker_count         = 1,
      worker_instance_type = "cx11",
    }
}

make create-lb

Install control plane

Generate the default talos config

make create-config create-templates

And deploy the kubernetes master nodes

make create-controlplane

Bootstrap the first node

talosctl --talosconfig _cfgs/talosconfig config endpoint $controlplane_firstnode
talosctl --talosconfig _cfgs/talosconfig --nodes $controlplane_firstnode bootstrap

make create-kubeconfig

Deploy all other instances

make create-infrastructure
