Example - AWS and Atlas together with Terraform

This project aims to provide a very straight-forward example of using AWS and MongoDB Atlas together.

Dependencies

1. Ensure your AWS credentials are set up.

This can be done using environment variables:

$ export AWS_SECRET_ACCESS_KEY='your secret key'
$ export AWS_ACCESS_KEY_ID='your key id'

... or the ~/.aws/credentials file.

$ cat ~/.aws/credentials
[default]
aws_access_key_id = your key id
aws_secret_access_key = your secret key

... or follow as in the variables.tf file and create terraform.tfvars file with all the variable values and make sure not to commit it.

2. Review the Terraform plan.

Execute the below command and ensure you are happy with the plan.

$ terraform plan

This project currently does the below deployments:

MongoDB cluster - M10
MongoDB User (Pass the values when asked)
AWS Custom VPC, Internet Gateway, Route Tables, Subnets with Public and Private access
AWS-MongoDB Atlas VPC Peering

3. Execute the Terraform apply.

Now execute the plan to provision the AWS resources.

$ terraform apply

4. Destroy the resources.

Once you are finished your testing, ensure you destroy the resources to avoid unnecessary AWS charges.

$ terraform destroy
