terraform-aws-iam-system-user

Terraform Module to provision a basic IAM system user suitable for CI/CD Systems (e.g. TravisCI, CircleCI) or systems which are external to AWS that cannot leverage AWS IAM Instance Profiles.

We do not recommend creating IAM users this way for any other purpose.

This project is part of our comprehensive "SweetOps" approach towards DevOps.

It's 100% Open Source and licensed under the APACHE2.

We literally have hundreds of terraform modules that are Open Source and well-maintained. Check them out!

Usage

IMPORTANT: The master branch is used in source just as an example. In your code, do not pin to master because there may be breaking changes between releases. Instead pin to the release tag (e.g. ?ref=tags/x.y.z) of one of our latest releases.

module "circleci" {
  source     = "git::https://github.com/cloudposse/terraform-aws-iam-system-user.git?ref=master"
  namespace  = "eg"
  stage      = "circleci"
  name       = "assets"
}

Examples

data "aws_iam_policy_document" "fluentd_user_policy" {
  statement {
    actions = [
      "logs:DescribeDestinations",
      "logs:DescribeExportTasks",
      "logs:DescribeLogGroups",
      "logs:DescribeLogStreams",
      "logs:DescribeMetricFilters",
      "logs:DescribeSubscriptionFilters",
      "logs:FilterLogEvents",
      "logs:GetLogEvents",
      "logs:CreateLogGroup",
      "logs:CreateLogStream",
      "logs:PutLogEvents",
      "logs:DescribeLogStreams",
      "logs:CreateLogStream",
      "logs:DeleteLogStream",
    ]

    resources = ["*"]
  }
}

module "fluentd_user" {
  source    = "git::https://github.com/cloudposse/terraform-aws-iam-system-user.git?ref=master"
  namespace = "eg"
  stage     = "dev"
  name      = "fluentd"
}


resource "aws_iam_user_policy" "default" {
  name   = "${module.fluentd_user.user_name}"
  user   = "${module.fluentd_user.user_name}"
  policy = "${data.aws_iam_policy_document.fluentd_user_policy.json}"
}
