Get Informations

Get your hosts resourcepool ID by selecting the host(s)

variable "hosts" {
  default = [
    "esx-01.example.com",
    "esx-02.example.com",
    "esx-03.example.com"
  ]
}data "vsphere_resource_pool" "resource_pool" {
    count         = length(var.hosts)
    name          = "${data.vsphere_host.hosts.*.name[count.index]}/Resources"
    datacenter_id = "${data.vsphere_datacenter.dc.id}"
}output "resourcepool_by_hosts" {
  value = data.vsphere_resource_pool.resource_pool
}

Get your hosts resourcepool ID by selecting the resourcepools

variable "hosts" {
  default = [
    "esx-01.example.com",
    "esx-02.example.com",
    "esx-03.example.com"
  ]
}data "vsphere_host" "hosts" {
  count         = length(var.hosts)
  name          = var.hosts[count.index]
  datacenter_id = data.vsphere_datacenter.dc.id
}output "resourcepool_by_resourcepool" {
  value = data.vsphere_host.hosts
}

The Module call:

module "kcluster_db" {
  source = "../terraform/modules/terraform-module-vmware_vm"
  host_count = 1
  name = "kcluster-db"
  domain = "domain.local"
  resource_pool_id = "resgroup-13"
  datastore_id = data.vsphere_datastore.datastore_esx.id
  num_cpus = "1"
  mem_in_mb = "2048"
  guest_id = "debian9Guest"
  scsi_type = data.vsphere_virtual_machine.template_debian10.scsi_type
  network_id = data.vsphere_network.network.id
  adapter_type = data.vsphere_virtual_machine.template_debian10.network_interface_types[0]
  size = "20"
  eagerly_scrub = data.vsphere_virtual_machine.template_debian10.disks.0.eagerly_scrub
  thin_provisioned = data.vsphere_virtual_machine.template_debian10.disks.0.thin_provisioned
  template_uuid = data.vsphere_virtual_machine.template_debian10.id
}

Import the existing VM into the Terraform State:

terraform import module.kcluster_db.vsphere_virtual_machine.kcluster_masters /path/vm/kcluster-db.domain.local
