How to install plugins
This charm supports installing both official and custom plugins for Indico, from pypi and from a git repositories.
The piwik and storage-s3 plugins are already packed as part of the charm. The list of available official plugins can be found here.
To install additional plugins, provide the configuration external_plugins as a comma separated list with the desired packages to be installed. Each element should be compatible with pip: e.g. juju config [charm_name] external_plugins=git+https://github.com/indico/indico-plugins-cern.git/#subdirectory=themes_cern,indico-plugin-themes-legacy.
The installed plugins can be upgraded by running the refresh-external-resources action. Note that the upgrade won’t take place if the published version hasn’t changed.
For more details on the configuration options and their default values see the configuration reference.
