Kubernetes Cluster resource missing externalloadbalanceripaddress and enablecsi parameters

[danielboothcloud]

Problem

The cloudstack_kubernetes_cluster resource is missing several parameters that are available in the CloudStack UI and API when creating Kubernetes clusters.

Missing Parameters

1. externalloadbalanceripaddress - Required for HA clusters (multiple control nodes) on Shared networks

   • Available in the UI when HA is enabled
   • Required to specify the external load balancer IP for API server access across control nodes
   • Without this, HA clusters on Shared networks cannot be created via Terraform

2. enablecsi - Enable CloudStack CSI (Container Storage Interface)

   • Available in the UI and API
   • Cannot enable CSI via Terraform

Impact

• HA Kubernetes clusters on Shared networks cannot be deployed via Terraform
• CSI cannot be enabled for clusters created via Terraform
• Users must manually configure these settings in the UI after Terraform deployment

Environment

• CloudStack: 4.22.0.0
• terraform-provider-cloudstack: latest

Expected Behavior

The resource should support all parameters available in the CloudStack API:

resource "cloudstack_kubernetes_cluster" "example" {
  name                        = "my-cluster"
  zone                        = "zone1"
  kubernetes_version          = "1.33.1"
  service_offering            = "Medium Instance"
  size                        = 3
  control_nodes_size          = 3  # HA cluster

  # These should be available but aren't:
  externalloadbalanceripaddress = "10.0.0.100"  # Missing
  enablecsi                   = true           # Missing
}
