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 = "[e-mail]: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"
  }
}
