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