IBM PowerVC Architect, Joe Cropper published an excellent article last year, in which he described how Terraform can be used with PowerVC, to deploy workloads in an Openstack environment. You can read it here:
https://developer.ibm.com/powervc/2017/06/29/infrastructure-code-terraform-meets-powervc/
I tested this in my lab recently. I downloaded Terraform to my Macbook and configured it to communicate with my PowerVC management server. Then I deployed a new AIX VM. It worked like a charm! I was impressed with how easy and quick it was to configure and use.
cgibson@xwing : ~/Downloads/TERRAFORM $ ./terraform -v
Terraform v0.11.7
+ provider.openstack v1.6.0
Following Joe’s instructions, I configured the main.tf file:
cgibson@xwing : ~/Downloads/TERRAFORM $ cat main.tf
provider "openstack" {
user_name = "pvcadmin"
password = "abc123"
tenant_name = "ibm-default"
domain_name = "Default"
auth_url = "https://pvc1:5000/v3/"
insecure = true
}
resource "openstack_compute_instance_v2" "TF-VM" {
name = "TF-VM"
image_id = "aaeb4f3c-7910-4365-96d7-0be5b45eb7fc"
flavor_id = "ee5e124b-03fc-4853-b6ad-a5cd34d75ffb"
network {
uuid = "1132cad9-8581-4f89-a25d-f7befcef5f32"
name = "VLAN55"
}
}
I deployed a new VM with “terraform apply”.
cgibson@xwing : ~/Downloads/TERRAFORM $ ./terraform apply

When I was done with the VM, I deleted it with “terraform destroy”.

Do you really want to destroy?
Terraform will destroy all your managed infrastructure, as shown above.
There is no undo. Only 'yes' will be accepted to confirm.
Enter a value: yes

Destroy complete! Resources: 1 destroyed.
On the PowerVC server, I saw corresponding messages appear in the log and observed the creation and deletion of the VM.
