### CREATE CORE-VCN ###
resource "oci_core_virtual_network" "CORE-VCN" {
cidr_block = "${var.cidr_block}"
dns_label = "${var.cust_code}VCN"
compartment_id = "${var.compartment_ocid}"
display_name = "${var.cust_code}-VCN" }
Don’t automate a long process; change the process!
PS C:\temp\Terraform> oci compute instance list --compartment-id
