Terraform Vsphere provider - getting the VM's UUID or MOID

[SurferL]

This is a repost of this issue: https://github.com/terraform-providers/terraform-provider-vsphere/issues/423

I'm slightly confused with the syntax of how to get the UUID or MOID of the newly generated VM, referenced in the documentation.

I thought it would be: ${data.vsphere_virtual_machine.id}, but data requires four parts...so trying with something along the lines of ${data.vsphere_virtual_machine.vm.id} failed as well.

Can you point me in the right direction for the syntax to get the UUID or MOID?

Thanks!

Idea behind requiring the MOID or UUID of the newly generated VM is to pass it into a remote-exec call, with which I can use in a script to have a unique name for the VM.

Hi, 

How did you call your data sphere_virtual_machine resource?

If you went like this :

data "vsphere_virtual_machine" "template" {
  name          = "test-vm-template"
  datacenter_id = "${data.vsphere_datacenter.dc.id}"
}

Then you will get the UUID with this variable: "${data.sphere_virtual_machine.template.id}".

The third part of the variable name is the name you gave to the "data" declaration.

Best regards,

Thomas

Hi,

Thanks for the response,

I am calling the data vsphere_virtual_machine resource as you do above.

However when running, I get the following error:

Error: resource 'vsphere_virtual_machine.vpshere_build_machine' provisioner remote-exec (#3): unknown resource 'data.vpshere_virtual_machine.template' referenced in variable data.vpshere_virtual_machine.template.id

Error: resource 'vsphere_virtual_machine.vpshere_build_machine' provisioner remote-exec (#3): unknown resource 'data.vpshere_virtual_machine.template' referenced in variable data.vpshere_virtual_machine.template.moid

Running vsphere provider version 1.1.0

[Thomas Michel]

Can you show me the whole code?

It seems that terraform can't find ${data.vsphere_virtual_machine.template}. That would means that you didn't write the "data" "sphere_virtual_machine" "template" {} block.

Regards,

Thomas

Sure:

provider "vsphere" {

password = "${var.vsphere_password}"

allow_unverified_ssl = true

data "vsphere_datacenter" "dc" {

name = "${var.vsphere_datacenter}"

}

data "vsphere_datastore" "datastore" {

name = "${var.vsphere_datastore}"

datacenter_id = "${data.vsphere_datacenter.dc.id}"

}

name = "${var.vsphere_cluster}/Resources"

datacenter_id = "${data.vsphere_datacenter.dc.id}"

}

data "vsphere_network" "network" {

name = "VM Network"

}

data "vsphere_virtual_machine" "template" {

name = "${var.vm_template}"

datacenter_id = "${data.vsphere_datacenter.dc.id}"

}

# Create virtual machine and provision deployment with gitlab runner

}

disk {

size = "${data.vsphere_virtual_machine.template.disks.0.size}"

}

clone {

template_uuid = "${data.vsphere_virtual_machine.template.id}"

}

provisioner "remote-exec" {

connection {

type = "${var.connection_type}"

insecure = true

user = "${var.user}"

password = "${var.pwd}"

}

inline = [

"python ${var.working_dir}/script.py ${data.vpshere_virtual_machine.template.id} ${data.vpshere_virtual_machine.template.moid}"

}

[Thomas Michel]

You got a typo "${data.vpshere_" 

Didn't see it earlier

Well this is embarrassing... Sorry about that! 

And thanks for pointing me in the right direction :) 

Is getting the moid the same? (getting this error, without spelling mistake this time!)

* Resource 'data.vsphere_virtual_machine.template' does not have attribute 'moid' for variable 'data.vsphere_virtual_machine.template.moid'

[Thomas Michel]

No worries, it happened to me so many times :D

About the moid, I think it will depends on the vsphere provider version, in the latest, there is no moid in the attribute list :

Ah right okay -- Which moid does this refer to? https://www.terraform.io/docs/providers/vsphere/r/virtual_machine.html#moid

[Thomas Michel]

It's an attribute of the "resource" "vsphere_virtual_machine" configuration. When you instantiate a "data" configuration, this attribute does not exist. 

With a "data" configuration, you just fetch some informations about an existing resource in your infrastructure, but by no means you manage it with terraform.

Thomas
