Plugins are zip artifacts and the applications can load plugins from the file system on startup. This gives great flexibility as you can combine different sets of plugins with the already-built Docker images of your applications without re-compiling or re-building anything, but only restarting the affected applications.

To this end there is a Compose file deployment/docker/compose/plugins.yml configuring the applications to use plugins and a shell script deployment/docker/download-plugins.sh to download plugins from provided descriptor urls. For details how to use the script, please see the comment at the beginning of the script.
