markdown 用于将VSI部署到专用主机的Terraform示例

## Get current dedicated host details and guests
In this case the Dedicated Host I was testing against had not had any VSIs deployed on to it:

```
tycho ~ ◎ curl -s "https://$SOFTLAYER_USERNAME:$[e-mail]/rest/v3/SoftLayer_Virtual_DedicatedHost/10401/getObject"
{
    "accountId": 78003,
    "cpuCount": 56,
    "createDate": "2017-08-04T05:15:56-07:00",
    "diskCapacity": 1200,
    "id": 10401,
    "memoryCapacity": 242,
    "modifyDate": null,
    "name": "kbryandedihost"
}

tycho ~ ◎ curl -s "https://$SOFTLAYER_USERNAME:$[e-mail]/rest/v3/SoftLayer_Virtual_DedicatedHost/10401/getGuests" | pmj
[]
```

I then used the following `main.tf` file to deploy a VSI on to the host. 

```hcl
# Softlayer username
variable slusername {}

# SoftLayer API key
variable slapikey {}

# The datacenter to deploy to
variable datacenter {
  default = "dal10"
}

# The target operating system for the VSI
variable os {
  default = "UBUNTU_LATEST_64"
}

# The number of cores for the VSI
variable vm_cores {
  default = 4
}

# The amount of memory for the VSI
variable vm_memory {
  default = 4096
}

# The private vlan to deploy the virtual guests on to 
variable priv_vlan { 
  default = 2101937
}

# The public vlan to deploy the virtual guests on to 
variable pub_vlan { 
  default = 2101935
}

# The domain name for the virtual guests
variable domainname { 
  default = "cde.services"
}

provider "ibm" {
  softlayer_username = "${var.slusername}"
  softlayer_api_key  = "${var.slapikey}"
}

data "ibm_compute_ssh_key" "sshkey" {
    label = "tycho"
}

resource "ibm_compute_vm_instance" "node" {
    hostname = "dedivstest"
    domain = "${var.domainname}"
    os_reference_code = "${var.os}"
    datacenter = "${var.datacenter}"
    network_speed = 1000
    hourly_billing = true
    private_network_only = false 
    cores = "${var.vm_cores}"
    memory = "${var.vm_memory}"
    disks = [100, 100]
    local_disk = true
    private_vlan_id = "${var.priv_vlan}"
    public_vlan_id = "${var.pub_vlan}"
    ssh_key_ids = ["${data.ibm_compute_ssh_key.sshkey.id}"]
    dedicated_host_id = 10401
}
```
