- The UI is handled by the [proxy](/docs/networking/proxy-management.md) interface plugin by setting the `DOKKU_PROXY_PORT_MAP` config variable in the format of `scheme:host-port:container-port`. The default `nginx-vhosts` proxy plugin supports both the `http` and `https` schemes.
- buildpack apps will be set to `http:80:5000` and will also include `https:443:5000` if SSL is enabled.
- dockerfile apps with explicitly exposed ports (i.e. using the `EXPOSE` directive) will be configured with a listener on each exposed port that proxies to the same port of the deployed application container.
- You may override this behavior with the [`proxy:ports-*` commands](/docs/networking/proxy-management.md) or by directly setting `DOKKU_PROXY_PORT_MAP` with the `config:set` command
- dockerfile apps without explicitly exposed ports will behave the same as a buildpack app
- NOTE: These defaults **are not** automatically changed on subsequent pushes and must be manipulated with the aforementioned commands
- Plugins should *not* call the `dokku` binary directly. Clients using the `--app` argument are potentially broken, amongst others, when doing so. Instead, please source the `functions` file for a given plugin when attempting to call Dokku internal functions. As a result, the following Dokku commands are no longer publicly exposed:
