This provisions a new MariaDB database in an existing MariaDB instance. The instance must be reachable from Humanitec IPs.

Property Description
Resource Type mariadb
Account Type None



Name Type Description
host string The IP Address or hostname that the instance is available on.
port integer The port the instance is listening on.
append_host_to_user boolean [Optional] Azure Databases for Postgres and MySQL require usernames to have @servername appended to them. Set this to true for the Driver to append this automatically. (See: Azure Database connection strings)
copy_from_name string [Optional] If provided, specifies the database in the same instance to copy data from.


Name Type Description
dbcredentials object An object holding username and password properties for the PostgreSQL superuser.


Automatic population of database

MariaDB does not provide any standard way of duplicating databases. Instead, the suggested approach is to “dump and restore” a database using tools such as mariadb-dump/mysqldump.

This Driver emulates a dump and restore of the database - i.e. it serially copies data from the source database to the target database. It therefore suffers from limitations of dumping and restoring a database. The main issue is that if the source database is being written to, there are no guarantees about the data integrity in the resulting database. Consider a source database with 2 tables A and B:

  1. Table A is copied to the target database.
  2. New data is then written to Table A and Table B in the source database.
  3. Table B is copied from the source database to the target database.

The target database will now have the updated to table B but not table A.

This functionality should not be used for production databases or where data integrity must be guaranteed.
