# Websocket to Container

**Last reviewed:**  11 months ago 

Forwarding a Websocket request to a Container

WebSocket requests are automatically forwarded to a container using the default `fetch`method on the `Container` class:

JavaScript

```

import { Container, getContainer } from "@cloudflare/containers";


export class MyContainer extends Container {

  defaultPort = 8080;

  sleepAfter = "2m";

}


export default {

  async fetch(request, env) {

    // gets default instance and forwards websocket from outside Worker

    return getContainer(env.MY_CONTAINER).fetch(request);

  },

};


```
