# Proxy plugin

> New as of 0.5.0

As of dokku 0.5.0, the proxy functionality has been decoupled from the nginx-vhosts plugin into the proxy plugin. In the future this will allow other proxy software (HAproxy for example) to be used instead of nginx.

```
proxy:disable <app>                                                                          Disable proxy for app
proxy:enable <app>                                                                           Enable proxy for app
proxy:set <app> <proxy_type>                                                                 NOT IMPLEMENTED YET!!
```

## Container network interface binding

By default, the deployed docker container running your app's web process will bind to the internal docker network interface (i.e. `docker inspect --format '{{ .NetworkSettings.IPAddress }}' $CONTAINER_ID`). This behavior can be modified per app by disabling the proxy (i.e. `dokku proxy:disable <app>`). In this case, the container will bind to an external interface (i.e. 0.0.0.0) and your app container will be directly accessible by other hosts on your network.

```shell
# container bound to docker interface
root@dokku:~/dokku# docker ps
CONTAINER ID        IMAGE                      COMMAND                CREATED              STATUS              PORTS               NAMES
