AWS RDS Terraform module

Terraform module which creates RDS resources on AWS.

These types of resources are supported:

• DB Instance
• DB Subnet Group
• DB Parameter Group

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 group

Usage

module "db" {
  source = "terraform-aws-modules/rds/aws"

  identifier = "demodb"

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

  name     = "demodb"
  username = "user"
  password = "YourPwdShouldBeLongAndSecure!"
  port     = "3306"

  iam_database_authentication_enabled = true

  vpc_security_group_ids = ["sg-12345678"]

  maintenance_window = "Mon:00:00-Mon:03:00"
  backup_window      = "03:00-06:00"

  # Enhanced Monitoring - see example for details on how to create the role
  # by yourself, in case you don't want to create it automatically
  monitoring_interval = "30"
  monitoring_role_name = "MyRDSMonitoringRole"
  create_monitoring_role = true

  tags = {
    Owner       = "user"
    Environment = "dev"
  }

  # DB subnet group
  subnet_ids = ["subnet-12345678", "subnet-87654321"]

  # DB parameter group
  family = "mysql5.7"

  # Snapshot name upon DB deletion
  final_snapshot_identifier = "demodb"

  parameters = [
    {
      name = "character_set_client"
      value = "utf8"
    },
    {
      name = "character_set_server"
      value = "utf8"
    }
  ]
}

Conditional creation

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
}

Examples

• Complete RDS example for MySQL
• Complete RDS example for PostgreSQL
• Complete RDS example for Oracle
• Complete RDS example for MSSQL
• Enhanced monitoring example

Notes

1. This module does not create RDS security group. Use terraform-aws-security-group module for this.
