Terraform AWS Account ID

Introduction

In Terraform, you can retrieve the AWS Account ID that your Terraform code is using. This is useful in various scenarios, such as dynamically configuring resources or managing access control. In this guide, we will explore how to retrieve the AWS Account ID using Terraform.

Retrieve AWS Account ID

To retrieve the AWS Account ID in Terraform, you can use the data block along with the aws_caller_identity data source. Here's an example code snippet:

data "aws_caller_identity" "current" {}

output "account_id" {
  value = data.aws_caller_identity.current.account_id
}

The above code snippet uses the aws_caller_identity data source to retrieve the AWS Account ID and then assigns it to the account_id output variable.

Explanation

Let's go through the code snippet step by step:

1. We define a data block with the aws_caller_identity data source. This data source retrieves the caller identity information.
2. We define an output block to display the Account ID retrieved from the aws_caller_identity data source.
3. Inside the output block, we specify the value as data.aws_caller_identity.current.account_id. This retrieves the Account ID from the aws_caller_identity data source.

By running terraform apply, Terraform will retrieve the AWS Account ID and display it as output.

Conclusion

In this guide, we have explored how to retrieve the AWS Account ID in Terraform using the aws_caller_identity data source. This can be helpful when you need to dynamically configure resources or manage access control within your Terraform code.
