**To create a DB instance**

The following ``create-db-instance`` example uses the required options to launch a new DB instance. ::

    aws rds create-db-instance \
        --db-instance-identifier test-mysql-instance \
        --db-instance-class db.t3.micro \
        --engine mysql \
        --master-username admin \
        --master-user-password secret99 \
        --allocated-storage 20

Output::
