Instance Method Details

#create_db_instance(identifier, instance_class, allocated_storage, master_username, master_password, options = {}) ⇒ Object

identifier: db instance identifier. Must be unique per account per zone. instance_class: db.m1.small | db.m1.large | db.m1.xlarge | db.m2.2xlarge | db.m2.4xlarge See this for other values: docs.amazonwebservices.com/AmazonRDS/latest/APIReference/

options:
