Starting with version 1.1.0-1 the Dudle App for UCS is available as Docker App. New installations automatically using this Docker App.

To update an existing non-Docker Dudle App to the new Docker Dudle App a manual migration has to be done.

The following steps are necessary to migrate the non-Docker Horde App to Docker:

Prepare Dudle App upgrade

ucr unset appcenter/prudence/docker/dudle

Upgrade Dudle App

univention-app update
univention-app upgrade dudle

During the upgrade all the App's data files and the config file config.rb are copied to the directory /var/lib/univention-appcenter/apps/dudle/data. This directory is mapped into the new Dudle container to provide the data and config to the new Docker Dudle App.

Further configurations or modifications of UCR settings have to be done in the container from now on. Use the following command to change into the new Dudle App container:

univention-app shell dudle
