In step 1, we should note that iam_pass is a variable defined in our variables file, protected by Ansible Vault for storing secrets.

In step 2, we wrote an IAM policy and saved that file with the name iam_admin.json.

In step 3, we created an IAM policy with the name Admin and attached that policy to the user cookbook-admin.

We should note here that we have used iam_type as a user here, which can be changed to a group or role. In a production environment, it's good practice to create IAM groups with attached policies and add users to the group. Also, changing iam_type to a role will create a role with a defined policy and can be used with various AWS resources.
