Terraform Module to provision a basic IAM user suitable for humans. It will establish a login profile and associate the user with IAM groups.

We do not recommend creating IAM users for any other purpose. For external systems (e.g. CI/CD) check out our terraform-aws-iam-system-user module.

[!TIP]

👽 Use Atmos with Terraform

Cloud Posse uses atmos to easily orchestrate multiple environments using Terraform. Works with Github Actions, Atlantis, or Spacelift.
<details> <summary>Watch demo of using Atmos with Terraform</summary> <img src="https://github.com/cloudposse/atmos/blob/master/docs/demo.gif?raw=true"/> Example of running <a href="https://atmos.tools"><code>atmos</code></a> to manage infrastructure from our <a href="https://atmos.tools/quick-start/">Quick Start</a> tutorial. </detalis>

Usage

First, make sure all users register with keybase.io to faciliate public key encryption (PKE). Then use their keybase username to automatically encrypt their AWS secret. It's that easy!

module "jack" {
  source = "cloudposse/iam-user/aws"
  # Cloud Posse recommends pinning every module to a specific version
  # version     = "x.x.x"
  name       = "jack"
  user_name  = "jack@companyname.com"
  pgp_key    = "keybase:jack"
  groups     = ["admins"]
}

NOTE: We recommend using email addresses for IAM user accounts.

[!IMPORTANT] In Cloud Posse's examples, we avoid pinning modules to specific versions to prevent discrepancies between the documentation and the latest released versions. However, for your own projects, we strongly advise pinning each module to the exact version you're using. This practice ensures the stability of your infrastructure. Additionally, we recommend implementing a systematic approach for updating versions to avoid unexpected changes.

Examples

module "jill" {
  source = "cloudposse/iam-user/aws"
  # Cloud Posse recommends pinning every module to a specific version
  # version     = "x.x.x"
  name      = "jill"
  user_name  = "jill@companyname.com"
  pgp_key    = "keybase:jill"
  groups    = ["engineering"]
}

<a name="input_additional_tag_map"></a> additional_tag_map	Additional key-value pairs to add to each map in `tags_as_list_of_maps`. Not added to `tags` or `id`.<br/>This is for some rare cases where resources want additional configuration of tags<br/>and therefore take a list of maps with tag key, value, and additional configuration.	`map(string)`	`{}`	no
<a name="input_attributes"></a> attributes	ID element. Additional attributes (e.g. `workers` or `cluster`) to add to `id`,<br/>in the order they appear in the list. New attributes are appended to the<br/>end of the list. The elements of the list are joined by the `delimiter`<br/>and treated as a single ID element.	`list(string)`	`[]`	no
<a name="input_context"></a> context	Single object for setting entire context at once.<br/>See description of individual variables for details.<br/>Leave string and numeric variables as `null` to use default value.<br/>Individual variable settings (non-null) override settings in context object,<br/>except for attributes, tags, and additional_tag_map, which are merged.	`any`	<pre>{<br/> "additional_tag_map": {},<br/> "attributes": [],<br/> "delimiter": null,<br/> "descriptor_formats": {},<br/> "enabled": true,<br/> "environment": null,<br/> "id_length_limit": null,<br/> "label_key_case": null,<br/> "label_order": [],<br/> "label_value_case": null,<br/> "labels_as_tags": [<br/> "unset"<br/> ],<br/> "name": null,<br/> "namespace": null,<br/> "regex_replace_chars": null,<br/> "stage": null,<br/> "tags": {},<br/> "tenant": null<br/>}</pre>	no

<a name="input_descriptor_formats"></a> descriptor_formats	Describe additional descriptors to be output in the `descriptors` output map.<br/>Map of maps. Keys are names of descriptors. Values are maps of the form<br/>`{<br/> format = string<br/> labels = list(string)<br/>}`<br/>(Type is `any` so the map values can later be enhanced to provide additional options.)<br/>`format` is a Terraform format string to be passed to the `format()` function.<br/>`labels` is a list of labels, in order, to pass to `format()` function.<br/>Label values will be normalized before being passed to `format()` so they will be<br/>identical to how they appear in `id`.<br/>Default is `{}` (`descriptors` output will be empty).	`any`	`{}`	no
<a name="input_enabled"></a> enabled	Set to false to prevent the module from creating any resources	`bool`	`null`	no

<a name="input_label_order"></a> label_order	The order in which the labels (ID elements) appear in the `id`.<br/>Defaults to ["namespace", "environment", "stage", "name", "attributes"].<br/>You can omit any of the 6 labels ("tenant" is the 6th), but at least one must be present.	`list(string)`	`null`	no
<a name="input_label_value_case"></a> label_value_case	Controls the letter case of ID elements (labels) as included in `id`,<br/>set as tag values, and output by this module individually.<br/>Does not affect values of tags passed in via the `tags` input.<br/>Possible values: `lower`, `title`, `upper` and `none` (no transformation).<br/>Set this to `title` and set `delimiter` to `""` to yield Pascal Case IDs.<br/>Default value: `lower`.	`string`	`null`	no
