terraform-aws-rds

Terraform module to provision AWS RDS instances

This project is part of our comprehensive "SweetOps" approach towards DevOps.

It's 100% Open Source and licensed under the APACHE2.

We literally have hundreds of terraform modules that are Open Source and well-maintained. Check them out!

Introduction

The module will create:

DB instance (MySQL, Postgres, SQL Server, Oracle)
DB Option Group (will create a new one or you may use an existing)
DB Parameter Group
DB Subnet Group
DB Security Group
DNS Record in Route53 for the DB endpoint

Usage

IMPORTANT: The master branch is used in source just as an example. In your code, do not pin to master because there may be breaking changes between releases. Instead pin to the release tag (e.g. ?ref=tags/x.y.z) of one of our latest releases.
