Hello @jdeighton
Yes, that is possible. Here is also part of this in the documentation: https://docs.cloudron.io/guides/connect-mysql/
But! Not documented is the part how to access the main DB, since this is risky and most users should not do that.
It is present in multiple forum posts so here.
While connect to the root user on the server, run:
docker exec -ti mysql /bin/bash
and inside the container you can simply run:
mysql -uroot -p$CLOUDRON_MYSQL_ROOT_PASSWORD
