New as of 0.5.0, Enhanced in 0.6.0

In Dokku 0.5.0, port proxying was decoupled from the
nginx-vhosts plugin into the proxy plugin. Dokku 0.6.0 introduced the ability to map host ports to specific container ports. In the future this will allow other proxy software - such as HAProxy or Caddy - to be used in place of nginx.
Changed as of 0.11.0
From Dokku versions
0.11.0, enabling or disabling an application's proxy would also control whether or not the application was bound to all interfaces - e.g.
0.0.0.0. As of
0.11.0, this is now controlled by the network plugin. Please see the network documentation for more information.
New as of 0.8.1
You can get a report about the app's proxy status using the
=====> node-js-app proxy information Proxy enabled: true Proxy type: nginx Proxy port map: http:80:5000 https:443:5000 =====> python-sample proxy information Proxy enabled: true Proxy type: nginx Proxy port map: http:80:5000 =====> ruby-sample proxy information Proxy enabled: true Proxy type: nginx Proxy port map: http:80:5000
You can run the command for a specific app also.
dokku proxy:report node-js-app
=====> node-js-app proxy information Proxy enabled: true Proxy type: nginx Proxy port map: http:80:5000 https:443:5000
You can pass flags which will output only the value of the specific information you want. For example:
dokku proxy:report node-js-app --proxy-type
The proxy port scheme is as follows:
The scheme metadata can be used by proxy implementations in order to properly handle proxying of requests. For example, the built-in
nginx-vhosts proxy implementation supports both the
Developers of proxy implementations are encouraged to use whatever schemes make the most sense, and ignore configurations which they do not support. For instance, a
udp proxy implementation can safely ignore
https port mappings.
To change the proxy implementation in use for an application, use the
# no validation will be performed against # the specified proxy implementation dokku proxy:set node-js-app nginx
