Terraform | Episode 34 | Introduction to Terraform Data Source | Understanding Terraform Data Source

====================================================================
====================================================================

Hello,

In this session, we will look at an introduction and get an understanding on Terraform data sources. Data source block can be used to refer to the existing resources and use them to create some additional resources. For example, we have an existing subnet in AWS and we want to launch an instance in this existing subnet using Terraform. Instead of hard-coding the subnet value, we can fetch the value from AWS using the data source block and then provide that information in the resource block to launch the instance in the AWS console.

Happy learning!!
