# Proxy plugin
|
|
|
|
> New as of 0.5.0
|
|
> Port handling functionality is new as of 0.6.0
|
|
|
|
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 <app> Show proxy settings for app
|
|
proxy:disable <app> Disable proxy for app
|
|
proxy:enable <app> Enable proxy for app
|
|
proxy:ports <app> List proxy port mappings for app
|
|
proxy:ports-add <app> <scheme>:<host-port>:<container-port> [<scheme>:<host-port>:<container-port>...] Set proxy port mappings for app
|
|
proxy:ports-clear <app> Clear all proxy port mappings for app
|
|
proxy:ports-remove <app> <host-port> [<host-port>...] Unset proxy port mappings for app
|
|
proxy:set <app> <proxy-type> Set proxy type for app
|
|
```

## 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.
|
|
|
|
> If a proxy is disabled, dokku will bind your container's port to a random port on the host, e.g. `0.0.0.0:32771->5000/tcp`.
|
|
|
|
```shell
|
|
# container bound to docker interface
|
|
root@dokku:~/dokku# docker ps
|
|
