Plugins

Dokku itself is built out of plugins and uses plugn for its plugin system. In essence a plugin is a collection of scripts that will be run based on naming convention.

Let's take a quick look at the current Dokku nginx plugin that's shipped with Dokku by default.

nginx-vhosts/
├── plugin.toml  # plugin metadata
├── commands     # contains additional commands
├── install      # runs on Dokku installation
└── post-deploy  # runs after an app is deployed
