Install Plugins (Packages)

Note: this guide only applies if you've installed OpenProject using our DEB/RPM packages.

A number of plugins exist for use with OpenProject. Most plugins that are maintained by us are shipping with OpenProject, however there are several plugins contributed by the community.

Previously, using them in a packaged installation was not possible without losing your changes on every upgrade. With the following steps, you can now use third party plugins.

Note: We cannot guarantee upgrade compatibility for third party plugins nor do we provide support for them. Please carefully check whether the plugins you use are available in newer versions before upgrading your installation.

1. Add a custom Gemfile

If you have a plugin you wish to add to your packaged OpenProject installation, create a separate Gemfile with the Gem dependencies, such as the following:

gem 'openproject-emoji', git: '', :branch => 'op-5-stable'

We suggest to store the Gemfile under /etc/openproject/Gemfile.custom, but the choice is up to you, just make sure the openproject user is able to read it.

2. Propagate the Gemfile to the package

You have to tell your installation to use the custom gemfile via a config setting:

openproject config:set CUSTOM_PLUGIN_GEMFILE=/etc/openproject/Gemfile.custom

3. Re-run the installer

To re-bundle the application including the new plugins, as well as running migrations and precompiling their assets, simply re-run the installer while using the same configuration as before.

openproject configure

Using configure will take your previous decisions in the installer and simply re-apply them, which is an idempotent operation. It will detect the Gemfile config option being set and re-bundle the application with the additional plugins.
