This module is part of a project to simplify the provisioning of MongoDB on AWS cloud using Terraform. You may also wish to consider one of the other approaches.

Terraform module to provision MongoDB using Packer

A terraform module to launch the single tier mongo instance on AWS.

These types of resources are supported: EC2 instance

Tech

• [Terraform] - Terraform enables you to safely and predictably create, change, and improve infrastructure. It is an open source tool that codifies APIs into declarative .

Installation

Install terraform using below documentation

https://learn.hashicorp.com/terraform/getting-started/install.html

Dependencies

Before you start using this module, you need create your own mongodb AMI modules. ami id of custom mongodb image

To build Mongodb AMI:

You can start building your images using this packer-repo. You can pass the created AMI id to the this module.

Module usage

module "terraform-mongodb" {
  source = "git@github.com:everest-engineering/terraform-aws-mongodb-packer.git"
  ami = "ami-0091d303b9f45e661"
  instance_type = "t2.micro"
  subnet_id = "subnet-eddcdzz4"
  vpc_security_group_ids=["sg-12345678"]
  key_name="deployer-key1"
  platform="ubuntu-18.04"
  mongodb_version="4.2"
  ami_version="1.0"
  tags = {
    Name = "New packer mongo"
  }
}
