IAM Users and IAM Groups

Overview

This service contains Terraform code to provision and manage best practices set of IAM Groups for permissions management, and configuring IAM Users that take advantage of those groups.

This feature exists in account-baseline-security, but having a separate module to manage IAM Users and Groups is useful for large scale organizations that frequently:

Onboard and offboard new users
Add and remove AWS accounts in their org

The rationale behind this change comes from addressing two issues:

The cadence of changes for IAM users and groups in the security account is considerably higher than the other things that are managed in account-baseline-security (e.g., consider CloudTrail, which should only be configured once in the lifetime of the account).
account-baseline-security is, by nature, a heavy module that manages tons of resources. Having to go through the plan and apply cycle for all those resources can be very painful, especially for large orgs that need to onboard/offboard user frequently.

Features

Provision IAM users with default set of IAM Groups, passwords, and access keys.
Manage a best practices set of IAM Groups for managing different permissions levels in your AWS Account.
Provision IAM Groups that manage cross account IAM Role access to other accounts in your AWS Organization.

usersanyoptional

A map of users to create. The keys are the user names and the values are an object with the optional keys 'groups' (a list of IAM groups to add the user to), 'tags' (a map of tags to apply to the user), 'pgp_key' (either a base-64 encoded PGP public key, or a keybase username in the form keybase:username, used to encrypt the user's credentials; required if create_login_profile or create_access_keys is true), 'create_login_profile' (if set to true, create a password to login to the AWS Web Console), 'create_access_keys' (if set to true, create access keys for the user), 'path' (the path), and 'permissions_boundary' (the ARN of the policy that is used to set the permissions boundary for the user).

Type Details

Any types represent complex values of variable type. For details, please consult `variables.tf` in the source repo.

Examples

Example

   users = {
     alice = {
       groups = ["user-self-mgmt", "developers", "ssh-sudo-users"]
     }
  
     bob = {
       path   = "/"
       groups = ["user-self-mgmt", "ops", "admins"]
       tags   = {
         foo = "bar"
       }
     }
  
     carol = {
       groups               = ["user-self-mgmt", "developers", "ssh-users"]
       pgp_key              = "keybase:carol_on_keybase"
       create_login_profile = true
       create_access_keys   = true
     }
   }

Details

   Ideally, this would be a map of (string, object), but object does not support optional properties, and we want
   users to be able to specify, say, tags for some users, but not for others. We can't use a map(any) either, as that
   would require the values to all have the same type, and due to optional parameters, that wouldn't work either. So,
   we have to lamely fall back to any.

user_access_keys

A map of usernames to that user's access keys (a map with keys access_key_id and secret_access_key), with the secret_access_key encrypted with that user's PGP key (only shows up for users with create_access_keys = true). You can decrypt the secret_access_key on the CLI: echo <secret_access_key> | base64 --decode | keybase pgp decrypt

A map of usernames to that user's AWS Web Console password, encrypted with that user's PGP key (only shows up for users with create_login_profile = true). You can decrypt the password on the CLI: echo <password> | base64 --decode | keybase pgp decrypt
