Terraform module which creates RDS resources on AWS.
These types of resources are supported:
Root module calls these modules which can also be used separately to create independent resources:
- db_instance - creates RDS DB instance
- db_subnet_group - creates RDS DB subnet group
- db_parameter_group - creates RDS DB parameter group
- db_option_group - creates RDS DB option group

identifier = "demodb"
engine = "mysql"
engine_version = "5.7.19"
instance_class = "db.t2.large"
allocated_storage = 5

username = "user"

},
{

value = "37"
},
]
},
]
}There is also a way to specify an existing database subnet group and parameter group name instead of creating new resources like this:
# This RDS instance will be created using default database subnet and parameter group
module "db" {
source = "terraform-aws-modules/rds/aws"
db_subnet_group_name = "default"
parameter_group_name = "default.mysql5.7"
# ... omitted
