I absolutely would love this option - and by "option" i mean like maybe we can make it "optional". So that you can activate on your cloudron if you want, but if you don't want thats fine as well!

This is awesome!!! Thanks @nebulon

Thanks for clarifying. I could do that, but I’m only looking to put certain apps behind IP restriction, not all of them.

Maybe we could at least introduce an optimization of the databases from time to time. The size of the referenced "ttrss_entries" table went from an insane 1,238 MB (!) to 583 MB after optimization.
The following command, maybe via a button, should to the trick:

mysqlcheck -Aos --user=${MYSQL_USERNAME} --password=${MYSQL_PASSWORD} --host=${MYSQL_HOST};

@necrevistonnezr Still evaluating what is the best option to update existing installations. Most likely we won't do dist-upgrade automatically. Also, new installations will default to 18.04.
