requests to the appropriate service. You can disable this controller in the helm
chart if you use your ingress or gateway.

## Ports

The following is a table of the listening ports associated with Coder resources
in the cluster. The environment ports are:

- code-server: `13337`
- envagent (used for shell sessions): `26337`
- envagent (SSH proxy): `12212`

> **Note**: This table represents Coder's current behavior. It is subject to
> change in future releases.
