  type = string
  description = "Organiztion ID"
  default = "add-your-id" # add your id here
}

Then go to Access Manager section in your Atlas menu, you will see the API keys tab. Just make your own and copy it into variables.tf respectively

Make sure your api key have organization owner role

variable "public_key" {
  type = string
  default = "add-your-key" # add your
}

variable "private_key" {
  type = string
  default = "add-your-key" #add your

Now run the following command

cd mongo_terraform
terraform init # set up provider for atlas
terraform plan

You need to type yes to continue this process, then type terraform apply to deploy your cluster.

Again, don't forget to type yes to continue, this process will take a few minutes. Just chill

After all, you will get something like:

Apply complete! Resources: 4 added, 0 changed, 0 destroyed.

Outputs:

password = "123"
srv_address = "mongodb+srv://spotify-cluster.kdglyul.mongodb.net"
user = "root"

Just notice 3 last lines. You will need them to add into your .env to run the system. They are MONGODB_PASS, MONGODB_SRV and MONGODB_USER respectively in .env file. Just copy the values and patse to it.
