Understanding Terraform output
In this section, we are going to see how you can define the Terraform output file as well as what the best practices are for referencing the output of one resource as input for other dependent resources. We will be discussing Terraform output for AWS, GCP, and Azure.
Terraform output
Let's try to understand what this Terraform output is and ideally, what we can achieve from it, as well as why we need to define Terraform output for any of the Terraform configuration files. Output values are the return values of a Terraform resource/module/data, and they have many use cases:
- The output from one resource/module/data can be called into other resources/modules/data if there is a dependency on the first resource. For example, if you want to create an Azure subnet and you have already created an Azure virtual network, then, in order to provide the reference of your virtual network in the subnet, you can use the output of the virtual network...
