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 being in the parent folder. If you change its location be sure to adjust the source attribute in main.tf.

Examples

Default configuration

  source = "./fabric/modules/cloud-config-container/envoy-traffic-director"

  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
  }
  boot_disk = {
    image = "projects/cos-cloud/global/images/family/cos-stable"
    type  = "pd-ssd"
