AWS Command Line Interface (CLI) tools allow you to manage your AWS services from the command line. For it to work, you'll need to have an IAM user with appropriate permission configured for programmatic access and configure the AWS CLI tools on your machines.

The following configuration method of AWS CLI is applicable for all the platforms such as Windows, Linux, or any other UNIX-based operating systems, including macOS. It creates a single profile named default by default, though you can also configure it for multiple profiles or accounts.

  9. AWS Access Key ID and AWS Secret Access Key stored in ~/.aws/credentials
    $ cat .aws/credentials
    [default]
    aws_access_key_id = AKIAJ3TE4LUDC4I6SQDQ
    aws_secret_access_key = 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
  10. Default region name and Default output format are stored in ~/.aws/config.
    $ cat .aws/config
    [default]

    You could manually add the configuration later in the following format:

    default_output_format=your_preferred_format
  11. You can now run the aws command to execute upon your AWS account wherever you have the correct permission for.
