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.

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

Installing a plugin

# This command requires `root` permissions as the `install` and `install-dependencies`
# plugin triggers may utilize commands such as `apt-get`. For non-core plugins, please
# inspect those plugins before running the following command as `root` user.
sudo dokku plugin:install <git_url> [--committish tag/branch/commit|--name custom-plugin-name]

# previous versions (0.3.x and below) of dokku require a manual process to install plugins
cd /var/lib/dokku/plugins
git clone <git url>
dokku plugins-install
