Deploy Aviatrix Edge GCP. AWS doesn't support nested virtualization, except on .metal instances.

Software Requirements

Terraform Google Cloud SDK/GCloud CLI: Must use gcloud init and gcloud auth application-default login.

Compatibility

Module version	Terraform version	Controller version	Terraform provider version
v3.1.4	>= 1.3.0	>= 7.1	~>3.1.0

Module Attributes

Required

key	value

source	"terraform-aviatrix-modules/gcp-edge-demo/aviatrix"
version	"3.1.4"
edge_image_location	gcp_bucket/filename.qcow2
edge_image_filename	${path.module}/filename.qcow2
vm_ssh_key	Host/Test VM Public Key in string form. Must include user@domain at the end of the key.

*NOTE: edge_image_location and edge_image_filename are mutually exclusive, but one is required.

Optional

key	value
admin_cidr	CIDRs that can SSH to the Host VMs. For GCP, the IAP range is always allowed.
region	Define the region for the VM and Storage Account. "us-central1" is the default
pov_prefix	Name prefix to prepend to all created resources. Default is "avx"
host_vm_size	Must be capable of virtualization. Default is "n2-standard-2"
host_vm_cidr	/28 is minimum size. Only need 3 IPs - 2x host VM plus ILB. Default is "10.40.251.16/28"
host_vm_asn	ASN for the host VMs. Default is "64900"
host_vm_count	Number of host VMs (and Edge VMs) to deploy. Default is "2"
test_vm_size	"Test VM size. Default is "e2-micro"
edge_vm_asn	ASN for Edge instances. Default is "64581"
edge_lan_cidr	The bridges on each host are connected at Layer 2 using VXLAN. 2 IPs per host VM. Default is "10.40.251.0/29"
test_vm_metadata_startup_script	Metadata startup script for the test vm. Default is `null`
external_cidrs	List of CIDRs that the Host VM should advertise into Edge. Static routes within the host VM will direct traffic to the subnet default gw. Default is "[]"
transit_gateways	List of Transit Gateways to add edge attachments. Default is "[]"
