Multi-instance is application capacity to be installed several times.
When YunoHost installs the application, it passes
$YNH_APP_INSTANCE_NAME var to the script, set to value
id__n with the application
id coming from the manifest and
n being an integer incremented each time a new instance of the application is installed.
E.g. in the roundcube script, database is called
roundcube, the install directory
roundcube and the Nginx configuration
roundcube. This way, the second instance of roundcube will not conflict with the first one, and will be installed in the
roundcube__2 database, in the
roundcube__2directory, and with the
roundcube__2 Nginx configuration.
