Hi Guys,

I have configured Terraform in the Windows system. I am using AWS as a provider. Can anyone tell me how are data sources used in Terraform?

Hi@akhtar,

A data source is accessed via a special kind of resource known as a data resource, declared using a data block.

data "aws_ami" "example" {
  most_recent = true
  owners = ["self"]
  tags = {
    Name   = "app-server"
    Tested = "true"
  }
}

A data block requests that Terraform read from a given data source ("aws_ami") and export the result under the given local name ("example"). The name is used to refer to this resource from elsewhere in the same Terraform module but has no significance outside of the scope of a module.
