# Containerized Envoy Proxy with Traffic Director on Container Optimized OS
|
|
|
|
This module manages a `cloud-config` configuration that starts a containerized Envoy Proxy on Container Optimized OS connected to Traffic Director. The default configuration creates a reverse proxy exposed on the node's port 80. Traffic routing policies and management should be managed by other means via Traffic Director.
|
|
|
|
The generated cloud config is rendered in the `cloud_config` output, and is meant to be used in instances or instance templates via the `user-data` metadata.
|
|
|
|
This module depends on the [`cos-generic-metadata` module](../cos-generic-metadata) being in the parent folder. If you change its location be sure to adjust the `source` attribute in `main.tf`.
|
|
|
|

|
|
module "vm" {
|
|
source = "./fabric/modules/compute-vm"
|
|
project_id = "my-project"
|
|
zone = "europe-west8-b"
|
|
name = "cos-envoy-td"
|
|
network_interfaces = [{
|
|
network = "default"
|
|
subnetwork = "gce"
|
|
}]
|
|
metadata = {
|
|
user-data = module.cos-envoy-td.cloud_config
|
|
google-logging-enabled = true
