Hey, when you take a look at the entrypoint.sh you'll see what's going on during the update.
It'll check if the config.php exists and if the database is initialized. If so, it'll run the console.php updatedb to upgrade the database if necessary. So changing the Image Tag and restarting the Container is enough to update.
so all uploaded (persitent) user data is stored to the upload/ directory. Any other data (in www/) is application specific, thus getting changed when changing the version of the image. So what you want to do, is to use a Volume for /var/www/html/upload/
If you change the Image version you'll get the new LS version and the uploaded data stays the same.
I'd be very happy to get feedback for improvement from the LS Team.
Cheers
so all my templates are in the upload directory, right? So if the updated Limesurvey Version still accepts the templates, everything should be fine?
What about the database, you need that running in a sperate container or elsewhere, right?
