-The MonetDB daemon [monetdbd](https://www.monetdb.org/Documentation/monetdbd-man-page) allows for multiple MonetDB database server processes to run on the same system and listed on the same port. While it is not advised to run more than one database server in the same Docker container, you can do that by creating a new database with the [monetdb](https://www.monetdb.org/Documentation/monetdb-man-page) command-line control tool.
