terraform-aws-mongodbatlas

Terraform module which creates a MongoDB Atlas cluster on AWS

These types of resources are supported:

Terraform versions

Terraform versions >=0.12 are supported

Usage

module "atlas_cluster" {
  source = ".//terraform-aws-mongodbatlas"

  project_name = "my-project"
  org_id = "5edf67f9b9b528996228111"

  teams = {
    Devops: {
      users: ["[email protected]", "[email protected]"]
      role: "GROUP_OWNER"
    },
    DevTeam: {
      users: ["[email protected]",]
      role: "GROUP_READ_ONLY"
    }
  }

  white_lists = {
    "example comment": "10.0.0.1/32",
    "second example": "10.10.10.8/32"
  }

  region = "EU_WEST_1"

  cluster_name = "MyCluster"

  instance_type = "M30"
  mongodb_major_ver = 4.2
  cluster_type = "REPLICASET"
  num_shards = 1
  replication_factor = 3
  provider_backup = true
  pit_enabled = false

}

Prerequisites

Manual tasks:

Configure the API key before applying the module
Get your MongoDB Atlas Organization ID from the UI

Create Teams:

In case you want to create Teams and associate them with the project, users must be added in advance and making sure they have accepted the invitation. Users who have not accepted an invitation to join the organization cannot be added as team members.

VPC Peering

In case vpc peering is required, AWS provider will be used, the following information is required:

You can add them manually, or through other Terraform resources, and pass it to the module via vpc_peer variable:

  vpc_peer = {
    vpc_peer1 : {
      aws_account_id : "020201234877"
      region : "eu-west-1"
      vpc_id : "vpc-0240c8a47312svc3e"
      route_table_cidr_block : "172.16.0.0/16"
    },
    vpc_peer2 : {
      aws_account_id : "0205432147877"
      region : "eu-central-1"
      vpc_id : "vpc-0f0dd82430bhv0e1a"
      route_table_cidr_block : "172.17.0.0/16"
    }
  }

You can see this example in the examples folder.
