Uninstalling

The default keeps your data. Purging is a separate, deliberate flag.

sudo ./uninstall.sh            # the containers; your data is kept
sudo ./uninstall.sh --purge    # and the data, permanently

The default is deliberately not the destructive one: removing the software is not the same as asking to lose your database. Installing again brings the same instance back.

Upgrading

Run the installer again. Nothing under the data directory is touched.

The data directory

/var/lib/cubeship — everything that must survive a container being replaced, and what each directory in it is.
