Boundary
Terraform

Users and groups in Boundary are collectively known as principals. Assigning grants on roles is performed through principal IDs; that is, the unique IDs of users, groups, or both.

This tutorial focus on completing user management tasks within a Boundary environment.

Prerequisites

This tutorial assumes that you successfully completed the Manage Scopes tutorial.

Users

Users in Boundary represent an internal notion of a particular entity (human, machine, etc.). Users can be correlated with one or more account resources via auth methods. Accounts represent external notions of a particular entity. Among other use-cases, this mechanism allows for an easy way to switch users to new IdPs within the organization deploying Boundary.

An auth method can be defined at the org and global scopes. In this tutorial, you will create an account and user for an auth method at the org level.

Currently, all auth methods create users upon authentication. If there is no user linked with an account, Boundary creates a user when the authentication against that account was successful. This behavior may be convenient, but in other situations (such as when you want Terraform to describe the Boundary resources), this may be undesirable. The steps in this tutorial demonstrate manually making these resources and linking them. A future Boundary update will allow turning off auto-vivification on a per-auth-method basis.

Add an auth method

Enable a password-type auth method in the IT_Support org which you created in the Manage Scopes tutorial.

Authenticate to Boundary as the admin user with the login name of password.

$ boundary authenticate
Please enter the login name (it will be hidden):
Please enter the password (it will be hidden):
Authentication information:
  Account ID:      acctpw_VOeNSFX8pQ
  Auth Method ID:  ampw_ZbB6UXpW3B
  Expiration Time: Mon, 13 Feb 2023 12:35:32 MST
  User ID:         u_1vUkf5fPs9
The token was successfully stored in the chosen keyring and is not displayed here.

Create a password auth method in the IT_Support org.

$ boundary auth-methods create password \
  -scope-id=$ORG_ID \
  -name="org_auth_method" \
  -description="Org auth method"

Example:

$ boundary auth-methods create password \
  -scope-id=$ORG_ID \
  -name="org_auth_method" \
  -description="Org auth method"

    authenticate

  Authorized Actions on Auth Method's Collections:
    accounts:
      create
      list
    managed-groups:
      create
      list

  Attributes:
    Minimum Login Name Length: 3
    Minimum Password Length:   8

In this example output, the password auth method ID is ampw_ZbB6UXpW3B.

Copy the auth method ID and save it as an environment variable, BOUNDARY_AUTH_METHOD_ID.

Example:

$ export BOUNDARY_AUTH_METHOD_ID=ampw_ZbB6UXpW3B

In your Terraform configuration file, define a boundary_auth_method resource to create a new auth method under the IT_Support scope which you created in the Manage Scopes tutorial.

resource "boundary_auth_method" "password" {
  name        = "org_auth_method"
  description = "Password auth method for org"
  type        = "password"
  scope_id    = boundary_scope.org.id
}

Create an account

Create an account for the org-scoped auth method.

Note

User names must be all lowercase alphanumeric of at least 3 characters and the password must be 8 or more characters. (The minimum lengths can be changed in the attributes for the auth method if desired.)

Create an account named "test_account". Give it a password supersecure when prompted.

$ boundary accounts create password \
  -auth-method-id=$BOUNDARY_AUTH_METHOD_ID \
  -login-name="tester01" \
  -name=test_account \
  -description="Test password account"

Example output:

$ boundary accounts create password \
  -auth-method-id=$BOUNDARY_AUTH_METHOD_ID \
  -login-name="tester01" \
  -name=test_account \
  -description="Test password account"
Please enter the password (it will be hidden):

    no-op
    read
    update
    delete
    set-password
    change-password

  Attributes:
    Login Name:        tester01

In this example, the generated account ID is acctpw_A8R1escktO.

Copy the ID of test_account and save it as an environment variable, ACCOUNT_ID.

$ export ACCOUNT_ID=acctpw_A8R1escktO

In your Terraform configuration file, define a boundary_account_password resource to create a new account in the org_auth_method you created in the previous step.

resource "boundary_account_password" "test_account" {
  name           = "test_account"
  description    = "Test password account"
  type           = "password"
  login_name     = "tester01"
  password       = "supersecure"
  auth_method_id = boundary_auth_method.password.id
}

Create a user

Next, create a user at the org scope.

Create a user, "tester01" under the IT_Support org.

$ boundary users create -name="tester01" -description="A test user" -scope-id=$ORG_ID

User information:
  Created Time:        Fri, 27 May 2022 11:17:35 MDT

    update
    delete
    add-accounts
    set-accounts
    remove-accounts

In the example output, the tester01 user ID is u_ogz79sV4sT.

Copy the generated user ID and save it as an environment variable, USER_ID.

Example:

$ export USER_ID=u_ogz79sV4sT

Now, associate the tester01 user with the test_account account previously created.

$ boundary users set-accounts -id=$USER_ID -account=$ACCOUNT_ID

In your Terraform configuration file, define a boundary_user resource to create a new user and associate that with test_account you created in the previous step.

resource "boundary_user" "tester01" {
  name        = "tester01"
  description = "A test user"
  account_ids = [
     boundary_account_password.test_account.id
  ]
  scope_id    = boundary_scope.org.id
}

Verify Users

Now, test to make sure that you can authenticate with Boundary as tester01 user.

Authenticate with Boundary using the newly created user, tester01. Enter supersecure at the Please enter the password (it will be hidden): prompt.

$ boundary authenticate
Please enter the login name (it will be hidden):

This tutorial utilizes the recovery key workflow to configure Boundary with Terraform utilizing the recovery_kms_hcl attribute of the boundary provider:

provider "boundary" {
  addr             = "http://127.0.0.1:9200"
  recovery_kms_hcl = <<EOT
kms "aead" {
  purpose = "recovery"
  aead_type = "aes-gcm"
  key = "Wt7KhwRKB05YlznYd5i5iPIezLHzbVFrKeZ2ewhoMwk="
  key_id = "global_recovery"
}
EOT
}

This is useful because it allows Boundary to be configured programmatically, without first bootstrapping Boundary with accounts or users.

Another approach uses a pre-existing account to manage Terraform resources. This method is not recommended, since authentication passwords should not be stored in HCL for production environments. If using this method, consider utilizing Terraform input variables instead. Also note that the account must already exist in order for Terraform to manage resources using this method.

Note

Do NOT copy the following snippet into your main.tf configuration. The following configuration is only provided as an example.

To configure the Boundary provider using Terraform, provide the valid auth method ID, login name, and password for a pre-existing auth method to authenticate. Note that a valid auth_method_id must be provided when configuring Boundary using this method, and the user must have appropriate grants assigned to manage resources in the desired scope. The next tutorial will discuss roles and grants.

provider "boundary" {
  addr                            = "http://127.0.0.1:9200"
  auth_method_id                  = "ampw_sOXVI7JS2l"
  password_auth_method_login_name = "tester01"
  password_auth_method_password   = "supersecure"
}

Do NOT add this configuration to your main.tf file.

Groups

A group in Boundary is a resource that represents a collection of users that are treated equally for the purposes of access control. A group is a principal, which allows it to be assigned to roles. Roles assigned to a group are indirectly assigned to the users in the group, and users receive all permissions of the assigned roles. Groups can be defined at the Global, Organization, or Project scope.

The group resource membership is managed manually. If using an OIDC Auth provider, such as Auth0, Okta or Azure AD, Managed Groups can be used to automatically map membership to a collection of accounts defined by the auth method's identity provider using filtering.

Create a group

Create a user at the org scope.

Create a group, "group01" under the IT_Support org.

$ boundary groups create -name="group01" -description="A test group" -scope-id=$ORG_ID

This tutorial demonstrated the steps to add a new authentication method to an org (IT_Support), created a new user and group within the org, and added the user as a member of the group. You verified that you can authenticate and logged into the IT_Support org using the newly created user credential.

The next step is to define the permissions to control what operations members of the group can perform. In the Manage Roles and Permissions tutorial, you will create a role, assign grants to the role, and then add the group as a principle of the new role. This group members will then inherit the defined permissions.
