aws_iam_user (Terraform)

The User in IAM can be configured in Terraform with the resource name aws_iam_user. The following sections describe 5 examples of how to use the resource and its parameters.

Example Usage from GitHub

iam_user.tf#L1
resource "aws_iam_user" "AIDAI5VAHO4Y6DRKF6X3Y" {
  name = "gamelift_player"
  path = "/"
  tags {}
}
iam_user.tf#L1
resource "aws_iam_user" "AIDAI5VAHO4Y6DRKF6X3Y" {
  name = "gamelift_player"
  path = "/"
  tags = {}
}
iam_user.tf#L1
resource "aws_iam_user" "AIDAI5VAHO4Y6DRKF6X3Y" {
  name = "gamelift_player"
  path = "/"
  tags {}
}
_users.tf#L1
resource "aws_iam_user" "phisinee_s" {
  name = "phisinee.s"

  tags = {
    email = "ange.l@pomelofashion.com"
  }
users-travis-ci.tf#L9
resource "aws_iam_user" "travis_ci_ack" {
  name = "travis-ci-ack"
}

resource "aws_iam_user" "travis_ci_aws_billing_alerts" {
  name = "travis-ci-aws-billing-alerts"

Parameters

Delete user even if it has non-Terraform-managed IAM access keys, login profile or MFA devices

>> from Terraform Registry

Explanation in Terraform Registry

Provides an IAM user.

NOTE: If policies are attached to the user via the aws_iam_policy_attachment resource and you are modifying the user name or path, the force_destroy argument must be set to true and applied before attempting the operation otherwise you will encounter a DeleteConflict error. The aws_iam_user_policy_attachment resource (recommended) does not have this requirement.

Tips: Best Practices for The Other AWS IAM Resources

In addition to the aws_iam_account_password_policy, AWS IAM has the other resources that should be configured for security reasons. Please check some examples of those resources and precautions.

risk-label

aws_iam_account_password_policy

Ensure AWS IAM account password policies requires long passwords

It's better to enforce the use of long and complex passwords to reduce the risk of bruteforce attacks.

Review your AWS IAM settings

In addition to the above, there are other security points you should be aware of making sure that your .tf files are protected in Shisho Cloud.
