In this tutorial, you will use Terraform to deploy a workspace containing a VPC and security groups on AWS in the us-east-1 region. Next, you will use the aws_availability_zones data source to configure your VPC's Availability Zones (AZs), allowing you to deploy this configuration in any AWS region. Then, you will use the terraform_remote_state data source to deploy another workspace containing your application infrastructure to your VPC. Finally, you will use the aws_ami data source to configure the correct AMI for the current region.
- Change to the VPC repository directory.
cd learn-terraform-data-sources-vpc- Add the
aws_availability_zones.availabletomain.tf. - Update the VPC configuration to use this data source to set the list of availability zones.
terrform initterraform apply -var aws_region=us-west-1- Add a data source to
main.tfto access region information. - Add an output for the region to
outputs.tf. terraform apply -var aws_region=us-west-1
