How can outputs be exported in Terraform?

Outputs in Terraform are exported using output blocks. When you define an output block in your Terraform configuration, you specify the values that you want to make accessible after the execution of the terraform apply command. These output values can include information such as IP addresses, resource IDs, or any other relevant data generated during the provisioning of infrastructure.

By utilizing output blocks, you allow for the sharing of this information across different parts of your Terraform configuration or make it available for use by other tools and processes. For example, outputs can be especially useful in scenarios where one module needs to reference resources created by another module, as they serve to bridge these relationships seamlessly.

The key distinction of output blocks is that they are explicitly designed for this purpose, making it easy for users and other systems to retrieve and utilize important configuration data after infrastructure provisioning is complete.
