# 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.
|
||
|
|
|
||
|
|
## Examples
