Deploying MongoDB Atlas With Terraform with Azure

export MONGODB_ATLAS_PUBLIC_KEY="<insert your public key here>"
2
export MONGODB_ATLAS_PRIVATE_KEY="<insert your private key here>"

1
# Define the MongoDB Atlas and Azure Providers
2
terraform {
3
  required_providers {
4
    mongodbatlas = {
5
      source = "mongodb/mongodbatlas"
6
      version = "=1.16.0"
7
    }
8
    azurerm = {
9
      source  = "hashicorp/azurerm"
10
      version = "=3.0.0"
11
    }
12
  }
13
}
14
Then, we start defining all the variables our configuration will use in the variables.tf file.

1
# Atlas Organization ID
2
variable "atlas_org_id" {
3
 type        = string
4
 description = "Atlas Organization ID"
5
}
6
# Atlas Project Name
7
variable "atlas_project_name" {
8
 type        = string
9
 description = "Atlas Project Name"
10
}
11
# Atlas Project Environment
12
 variable "environment" {
13
   type        = string
14
   description = "The environment to be built"
15
 }
16
# Cluster Instance Size Name
17
variable "cluster_instance_size_name" {
18
 type        = string
19
 description = "Cluster instance size name"
20
}
21
# Cloud Provider to Host Atlas Cluster
22
variable "cloud_provider" {
23
 type        = string
24
 description = "AWS or GCP or Azure"
25
}
26
# Atlas Region
27
variable "atlas_region" {
28
 type        = string
29
 description = "Atlas region where resources will be created"
30
}
31
# MongoDB Version
32
variable "mongodb_version" {
33
 type        = string
34
 description = "MongoDB Version"
35
}
36
# IP Address Access
37
variable "ip_address" {
38
 type = string
39
 description = "IP address used to access Atlas cluster"
40
}

1
atlas_org_id = "<UPDATE WITH YOUR ORG ID>"
2
atlas_project_name = "yourProjectName"
3
environment = "dev"
4
cluster_instance_size_name = "M10"
5
cloud_provider = "Azure"
6
atlas_region = "US_EAST_2"
7
mongodb_version = "7.0"
8
ip_address = "<UPDATE WITH YOUR IP>"

1
# Create a Project
2
resource "mongodbatlas_project" "atlas-project" {
3
 org_id = var.atlas_org_id
4
 name = var.atlas_project_name
5
}

1
# Create a Database User
2
resource "mongodbatlas_database_user" "db-user" {
3
 username = "user-1"
4
 password = random_password.db-user-password.result
5
 project_id = mongodbatlas_project.atlas-project.id
6
 auth_database_name = "admin"
7
 roles {
8
   role_name     = "readWrite"
9
   database_name = "${var.atlas_project_name}-db"
10
 }
11
}
12
# Create a Database Password
13
resource "random_password" "db-user-password" {
14
 length = 16
15
 special = true
16
 override_special = "_%@"
17
}
18
Next, we need to create the IP access list.
19
20
# Create Database IP Access List
21
resource "mongodbatlas_project_ip_access_list" "ip" {
22
 project_id = mongodbatlas_project.atlas-project.id
23
 ip_address = var.ip_address
24
}
25
We will need to put the IP address that we are connecting to the MongoDB Atlas cluster into the terraform.tfvars file.

1
resource "mongodbatlas_cluster" "test" {
2
 project_id   = mongodbatlas_project.atlas-project.id
3
 name         = "${var.atlas_project_name}-${var.environment}-cluster"
4
 cluster_type = "REPLICASET"
5
 replication_specs {
6
   num_shards = 1
7
   regions_config {
8
     region_name     = var.atlas_region
9
     electable_nodes = 3
10
     priority        = 7
11
     read_only_nodes = 0
12
   }
13
 }
14
 cloud_backup     = true
15
 auto_scaling_disk_gb_enabled = true
16
 mongo_db_major_version       = "7.0"
17
 # Provider Settings "block"
18
 provider_name               = var.cloud_provider
19
 provider_disk_type_name     = "P6"
20
 provider_instance_size_name = var.cluster_instance_size_name
21
}

1
output "cluster_name" {
2
 value = mongodbatlas_cluster.test.name
3
 description = "Name of the MongoDB Atlas cluster"
4
}
5
output "cluster_uri" {
6
 value = "mongodb://user-1:${random_password.db-user-password.result}@${mongodbatlas_cluster.test.name}.mongodb.net:27017/?authSource=admin&replicaSet=test-replicaSet"
7

8
 sensitive = true
9
}
10
output "project_id" {
11
 value = mongodbatlas_cluster.test.project_id
12
 description = "ID of the MongoDB Atlas project where the cluster resides"

}
