Google Simple NVA Module

This module allows for the creation of a NVA (Network Virtual Appliance) to be used for experiments and as a stub for future appliances deployment.

This NVA can be used to interconnect up to 8 VPCs.

Examples

Simple example

# Interfaces configuration
locals {
  network_interfaces = [
    {
      addresses  = null
      name       = "dev"
      nat        = false
      network    = "dev_vpc_self_link"
      routes     = ["10.128.0.0/9"]
      subnetwork = "dev_vpc_nva_subnet_self_link"
    },
    {
      addresses  = null
      name       = "prod"
      nat        = false
      network    = "prod_vpc_self_link"
      routes     = ["10.0.0.0/9"]
      subnetwork = "prod_vpc_nva_subnet_self_link"
    }
}

Variables

name	description	type	required	default
network_interfaces	Network interfaces configuration.	list(object({…}))	✓
cloud_config	Cloud config template path. If null default will be used.	string		null
enable_health_checks	Configures routing to enable responses to health check probes.	bool		false
test_instance	Test/development instance attributes, leave null to skip creation.	object({…})		null
test_instance_defaults	Test/development instance defaults used for optional configuration. If image is null, COS stable will be used.	object({…})		{…}

Outputs

name	description	sensitive
cloud_config	Rendered cloud-config file to be passed as user-data instance metadata.
test_instance	Optional test instance name and address.
