dokku plugins-install

These commands require 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.

You can check if a plugin has been installed via the plugin:installed command:

dokku plugin:installed postgres

Installing a plugin is easy as well using the plugin:install command. This command will also trigger the install pluginhook on all existing plugins.

dokku plugin:install https://github.com/dokku/dokku-postgres.git

-----> Cloning plugin repo https://github.com/dokku/dokku-postgres.git to /var/lib/dokku/plugins/available/postgres

-----> Plugin postgres enabled

You can also uninstall a third-party plugin using the plugin:uninstall command:

dokku plugin:uninstall postgres

-----> Plugin postgres uninstalled

Enabling or disabling a plugin can also be useful in cases where you are debugging whether a third-party plugin is causing issues in your Dokku installation:

dokku plugin:disable postgres

-----> Plugin postgres disabled

dokku plugin:enable postgres

-----> Plugin postgres enabled

Finally, you can update an installed third-party plugin. This should be done after any upgrades of Dokku as there may be changes in the internal api that require an update of how the plugin interfaces with Dokku.

dokku plugin:update postgres

Plugin (postgres) updated
