Terraform project which demonstrates full peering between 2 VPCs in Amazon Web Services.

Example - Peering 2 VPCs with Terraform

This project aims to provide a very straight-forward example of peering 2 entire VPCs using Terraform.

Terraform provisions the following architecture:

Once provisioning is complete, run the test script to validate each of the connections.

Dependencies

• Terraform v0.7 or greater
• An AWS account

Usage

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

2. Review the Terraform plan.

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

$ terraform plan

3. Execute the Terraform apply.

Now execute the plan to provision the AWS resources.

$ terraform apply

4. Run the test PHP script.

$ php test-instance-connectivity.php

5. Destroy the resources.

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

$ terraform destroy
