Currently, DUST provides 1 database solution: MariaDB (MySQL). To create a database, head over to the "Databases" tab of your project. There, you can create a new database, making sure to give it a unique and cool name. Like the warning says, the password will only be displayed once, so remember to jot it down. Keep in mind that you can only create a database connection from LUDD's network (which your container is running from), or alternatively you can browse the database from anywhere via the web interface hosted at mysql.ludd.ltu.se.
