Remote commands

Dokku commands can be run over ssh. Anywhere you would run dokku <command>, just run ssh -t dokku@progriumapp.com <command> The -t is used to request a pty. It is highly recommended to do so. To avoid the need to type the -t option each time, simply create/modify a section in the .ssh/config on the client side, as follows:

Host progriumapp.com
RequestTTY yes

Run a command in the app environment

It's possible to run commands in the environment of the deployed application:

dokku run node-js-app ls -alh
dokku run <app> <cmd>
