Manage GCP Dataplex AspectType IAM Policies

The gcp:dataplex/aspectTypeIamPolicy:AspectTypeIamPolicy resource, part of the Pulumi GCP provider, manages IAM access control for Dataplex AspectType resources using three distinct approaches. This guide focuses on three capabilities: authoritative policy replacement (AspectTypeIamPolicy), role-level member management (AspectTypeIamBinding), and incremental member addition (AspectTypeIamMember).

All three resources reference an existing AspectType by project, location, and aspectTypeId. The examples are intentionally small. Combine them with your own AspectType resources and organizational IAM structure.

Replace the entire IAM policy authoritatively

When you need complete control over AspectType access, replacing the entire IAM policy ensures no unexpected permissions remain.

import * as pulumi from "@pulumi/pulumi";
import * as gcp from "@pulumi/gcp";

const admin = gcp.organizations.getIAMPolicy({
    bindings: [{
        role: "roles/viewer",
        members: ["user:jane@example.com"],
    }],
});
const policy = new gcp.dataplex.AspectTypeIamPolicy("policy", {
    project: testAspectTypeBasic.project,
    location: testAspectTypeBasic.location,
    aspectTypeId: testAspectTypeBasic.aspectTypeId,
    policyData: admin.then(admin => admin.policyData),
});

import pulumi
import pulumi_gcp as gcp

admin = gcp.organizations.get_iam_policy(bindings=[{
    "role": "roles/viewer",
    "members": ["user:jane@example.com"],
}])
policy = gcp.dataplex.AspectTypeIamPolicy("policy",
    project=test_aspect_type_basic["project"],
    location=test_aspect_type_basic["location"],
    aspect_type_id=test_aspect_type_basic["aspectTypeId"],
    policy_data=admin.policy_data)

package main

func main() {
	pulumi.Run(func(ctx *pulumi.Context) error {
		admin, err := organizations.LookupIAMPolicy(ctx, &organizations.LookupIAMPolicyArgs{
			Bindings: []organizations.GetIAMPolicyBinding{
				{

			Location:     pulumi.Any(testAspectTypeBasic.Location),
			AspectTypeId: pulumi.Any(testAspectTypeBasic.AspectTypeId),
			PolicyData:   pulumi.String(admin.PolicyData),
		})
		if err != nil {
			return err
		}
		return nil
	})
}

          - role: roles/viewer
            members:
              - user:jane@example.com

The AspectTypeIamPolicy resource sets the complete IAM policy by consuming policyData from the getIAMPolicy data source. This approach is authoritative: it replaces any existing policy entirely. The aspectTypeId, location, and project properties identify which AspectType to manage. Use this when you want to define all permissions in one place, but note that it cannot coexist with AspectTypeIamBinding or AspectTypeIamMember resources on the same AspectType.

Grant a role to multiple members at once

Teams often need to grant the same role to several users without affecting other role assignments.

      aspectTypeId: ${testAspectTypeBasic.aspectTypeId}
      role: roles/viewer
      members:
        - user:jane@example.com

The AspectTypeIamBinding resource grants a specific role to a list of members. The role property specifies which permission set to grant, and members lists the identities receiving access. This resource is authoritative for its role: it replaces any existing members for that role, but preserves other roles on the AspectType. You can use multiple AspectTypeIamBinding resources on the same AspectType as long as they manage different roles.

Add a single member to a role incrementally

When you need to grant access to one user without coordinating with other administrators, incremental grants avoid conflicts.

import * as gcp from "@pulumi/gcp";

      role: roles/viewer
      member: user:jane@example.com

The AspectTypeIamMember resource adds a single member to a role without affecting existing members. The member property specifies one identity (user, service account, or group). This is the most granular option: it’s non-authoritative, so multiple AspectTypeIamMember resources can safely add different members to the same role. Use this when multiple teams manage access independently.

Beyond these examples

These snippets focus on specific IAM management approaches: authoritative vs incremental management and role-level vs member-level grants. They’re intentionally minimal rather than full access control configurations.

The examples reference pre-existing infrastructure such as Dataplex AspectType resources and GCP project and location configuration. They focus on IAM policy structure rather than provisioning the AspectTypes themselves.

To keep things focused, common IAM patterns are omitted, including:

Conditional IAM bindings (condition blocks)
Custom role definitions
Service account impersonation
IAM policy auditing and drift detection

These omissions are intentional: the goal is to illustrate how each IAM resource type is wired, not provide drop-in access control modules. See the AspectTypeIamPolicy resource reference for all available configuration options.

Frequently Asked Questions

Resource Selection & Conflicts

Why am I getting policy conflicts between my IAM resources?

AspectTypeIamPolicy is authoritative and will overwrite changes made by AspectTypeIamBinding or AspectTypeIamMember. Never use AspectTypeIamPolicy with the other two resources, or they will fight over the policy.

Can I use AspectTypeIamBinding and AspectTypeIamMember together?

Yes, but only if they manage different roles. Using both for the same role will cause conflicts.

Which IAM resource should I use for managing AspectType permissions?

Use AspectTypeIamPolicy to replace the entire policy authoritatively. Use AspectTypeIamBinding to manage all members for a specific role while preserving other roles. Use AspectTypeIamMember to add individual members non-authoritatively, preserving other members for the same role.

Import & Migration

How do I import IAM resources with custom roles?

Use the full name of the custom role: [projects/my-project|organizations/my-org]/roles/my-custom-role.
