Create service accounts

It’s a best practice to use service accounts (i.e., non-human users) to connect external applications and services to Materialize. As an administrator of a Materialize organization, you can create service accounts manually via the Materialize Console, or programatically via Terraform.

More granular permissions for the service account can then be configured using role-based access control (RBAC).

Materialize Console

! Important: For a new service account, after creating the new app password, you must connect with the service account to complete the account creation.
  1. Log in to the Materialize Console.

  2. In the side navigation bar, click + Create New > App Password.

  3. In the New app password modal, select Type > Service and name the new app password. Under User, specify the new service user you’d like to create and associate with the new app password.

  4. Under Roles, select Organization Admin or Organization Member depending on the level of database access the service user needs:

    • Organization Admin: has superuser privileges in the database.

    • Organization Member: has restricted access to the database, depending on the privileges defined via role-based access control (RBAC).

  5. Click Create Password to generate a new password for your service account.

  6. Store the new password securely.

    NOTE: Do not reload or navigate away from the screen before storing the password. This information is not displayed again.
  7. Connect with the new service account to finish creating the new account.

    1. Find your new service account in the App Passwords table.

    2. Click on the Connect button to get details on connecting with the new account.

      If you have psql installed:

      1. Click on the Terminal tab.
      2. From a terminal, connect using the psql command displayed.
      3. When prompted for the password, enter the app’s password.

      Once connected, the service account creation is complete and you can grant roles to the new service account.

      To use a different client to connect,

      1. Click on the External tools tab to get the connection details.

      2. Update the client to use these details and connect.

      Once connected, the service account creation is complete and you can grant roles to the new service account.

Terraform

Minimum requirements: terraform-provider-materialize v0.8.1+

  1. Create a new service user using the materialize_role resource:

    resource "materialize_role" "production_dashboard" {
      name   = "svc_production_dashboard"
      region = "aws/us-east-1"
    }
    
  2. Create a new service app password using the materialize_app_password resource, and associate it with the service user created in the previous step:

    resource "materialize_app_password" "production_dashboard" {
      name = "production_dashboard_app_password"
      type = "service"
      user = materialize_role.production_dashboard.name
      roles = ["Member"]
    }
    
  3. Optionally, associate the new service user with existing roles to grant it existing database privileges.

    resource "materialize_database_grant" "database_usage" {
      role_name     = materialize_role.production_dashboard.name
      privilege     = "USAGE"
      database_name = "production_analytics"
      region        = "aws/us-east-1"
    }
    
  4. Export the user and password for use in the external application or service.

    output "production_dashboard_user" {
      value = materialize_role.production_dashboard.name
    }
    output "production_dashboard_password" {
      value = materialize_app_password.production_dashboard.password
    }
