AWS CLI credentials

The Shared Credentials method involves using the AWS CLI’s credentials file, typically located at ~/.aws/credentials (or C:\Users\USERNAME\.aws\credentials on Windows). This method is useful when you’re already using AWS CLI and it helps you avoid hardcoding sensitive data in your scripts.

Example:

First, set up your credentials file using the AWS CLI. Open the command prompt and run the following command:

aws configure

Enter your AWS Access Key ID and Secret Access Key when prompted. The AWS CLI will save these credentials in a file.

Next, define the AWS provider in your Terraform script. Terraform will automatically source your credentials from the AWS CLI configuration files:

provider "aws" {
  region = "us-west-2"
}

If you’ve set up multiple profiles for AWS CLI, you can specify which profile to use in your Terraform scripts like this:

provider "aws" {
  region  = "us-west-2"
  profile = "customprofile" 
}

In this example, replace "customprofile" with the name of the profile you want to use from your AWS CLI configuration.
