VALIDATION STEPS

Scenario 1

1. On client node, utilize the following main.tf:

   
   terraform {
   required_providers {
   rke = {
     source  = "terraform.local/local/rke"
     version = "1.7.0-rc1"
   }
   }
   }

provider "rke" { log_file = var.log_file }

resource "rke_cluster" "cluster" { nodes { address = var.address1 user = var.user role = ["controlplane", "worker", "etcd"] ssh_key = file(var.ssh_key_path) } nodes { address = var.address2 user = var.user role = ["controlplane", "worker", "etcd"] ssh_key = file(var.ssh_key_path) } nodes { address = var.address3 user = var.user role = ["controlplane", "worker", "etcd"] ssh_key = file(var.ssh_key_path) } enable_cri_dockerd = true }

_NOTE:_ The kubeconfig is in `outputs.tf` and will not be shared here.
2. Run `terraform apply`.
3. Using the kubeconfig defined in `outputs.tf`, place that in `~/HOME/.kube/config`.
4. Run` kubectl get nodes`:

$ kubectl get nodes NAME STATUS ROLES AGE VERSION
