Google Compute Engine VM module
This module allows creating one or multiple instances or an instance template for a specific configuration. A service account is optionally created and assigned if not specified.
TODO
- add examples for instance groups
Examples
Instance leveraging defaults
The simplest example leverages defaults for the boot disk image and size, and uses a service account created by the module. Multiple instances can be managed via the instance_count
variable.
module "simple-vm-example" {
source = "../modules/compute-vm"
project_id = "my-project"
region = "europe-west1"
zone = "europe-west1-b"
name = "test"
network_interfaces = [{
network = local.network_self_link,
subnetwork = local.subnet_self_link,
nat = false,
addresses = null
}]
service_account_create = true
instance_count = 1
}
Instance template
This example shows how to use the module to manage an instance template that defines an additional attached disk for each instance, and overrides defaults for the boot disk image and service account.
module "debian-test" {
source = "../modules/compute-vm"
project_id = "my-project"
region = "europe-west1"
zone = "europe-west1-b"
name = "test"
network_interfaces = [{
network = local.network_self_link,
subnetwork = local.subnet_self_link,
nat = false,
addresses = null
}]
instance_count = 1
boot_disk = {
image = "projects/cos-cloud/global/images/family/cos-stable"
type = "pd-ssd"
size = 10
}
attached_disks = [
{ name = "disk-1", size = 10, image = null, options = null }
]
service_account = "vm-default@my-project.iam.gserviceaccount.com"
use_instance_template = true
}
