# The provider is the system we are connecting to or managing. In this case
# the provider is 'vsphere'. For the vSphere provider, we need to provide the 
# vCenter server and credentials to connect. In this example, we are using variables for this

provider "vsphere" {
  user           = var.vsphere_user
  password       = var.vsphere_password
  vsphere_server = var.vsphere_server

  # If you have a self-signed cert
  allow_unverified_ssl = true
}

# Terrafrom can use Variables to make your configurations more dynamic, for simplicity, we use
# the three variables below to feed values into the provider.

vsphere_user = "administrator@vsphere.local"
vsphere_password = "yoursecurepassword"
vsphere_server = "vcenterserver.local"

# Terraform is great at provisioning infrastructure, but it doesn't discover existing infrastructure 
# out of the box. Below we are using the data type to 'inform' Terrafrom that we have an existing DataCenter
# named A03. We need this, as some of the resources we will create require the datacenter

data "vsphere_datacenter" "datacenter" {
  name = "my_dc"
}

# We have two hosts to add to the vCenter, both have ESXi installed, but are yet to be adopted to the
# vCenter. The will be placed into maintenance mode when the are added.

resource "vsphere_host" "host_esx03" {
  hostname = "esx03.local"
  username = "root"
  password = "Password1"
  datacenter =  "${data.vsphere_datacenter.datacenter.id}"
  maintenance = true
}

# The second ESXi host

resource "vsphere_host" "host_esx04" {
  hostname = "esx04.local"
  username = "root"
  password = "Password1"
  datacenter = "${data.vsphere_datacenter.datacenter.id}"
  maintenance = true
}

# Lastly, we will create our host cluster, add the hosts and enable vSphere HA. The resource seems
# to understand that the ESXi hosts need to be created prior to the cluster creation. Interestingly,
# this creates a state that can no longer be updated. 

resource "vsphere_compute_cluster" "compute_cluster" {
  name            = "my_cluster"
  datacenter_id   = "${data.vsphere_datacenter.datacenter.id}"
  host_system_ids = ["${vsphere_host.host_esx03.id}","${vsphere_host.host_esx04.id}"]

  drs_enabled          = false
  drs_automation_level = "fullyAutomated"

  ha_enabled = true
