Manage GCP Dataplex Task IAM Permissions

The gcp:dataplex/taskIamMember:TaskIamMember resource, part of the Pulumi GCP provider, manages IAM permissions for Dataplex tasks by adding individual members to roles without affecting other permissions. This guide focuses on three approaches: adding single members to roles (TaskIamMember), managing all members for a role (TaskIamBinding), and replacing entire IAM policies (TaskIamPolicy).

These resources reference existing Dataplex tasks and require valid IAM principals. The examples are intentionally small. Combine them with your own task infrastructure and identity management.

Grant a single user access to a task

Most IAM configurations start by granting individual users or service accounts access to specific resources without disrupting existing permissions.

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

const member = new gcp.dataplex.TaskIamMember("member", {
    project: example.project,
    location: example.location,
    lake: example.lake,
    taskId: example.taskId,
    role: "roles/viewer",
    member: "user:jane@example.com",
});

import pulumi
import pulumi_gcp as gcp

member = gcp.dataplex.TaskIamMember("member",
    project=example["project"],
    location=example["location"],
    lake=example["lake"],
    task_id=example["taskId"],
    role="roles/viewer",
    member="user:jane@example.com")

package main

import (
	"github.com/pulumi/pulumi-gcp/sdk/v9/go/gcp/dataplex"
	"github.com/pulumi/pulumi/sdk/v3/go/pulumi"
)

func main() {
	pulumi.Run(func(ctx *pulumi.Context) error {
		_, err := dataplex.NewTaskIamMember(ctx, "member", &dataplex.TaskIamMemberArgs{
			Project:  pulumi.Any(example.Project),
			Location: pulumi.Any(example.Location),
			Lake:     pulumi.Any(example.Lake),
			TaskId:   pulumi.Any(example.TaskId),
			Role:     pulumi.String("roles/viewer"),
			Member:   pulumi.String("user:jane@example.com"),
		})
		if err != nil {
			return err
		}
		return nil
	})
}

      lake: ${example.lake}
      taskId: ${example.taskId}
      role: roles/viewer
      member: user:jane@example.com

The member property specifies one identity (user, service account, or group) to add to the role. The role property defines what permissions that identity receives. TaskIamMember is non-authoritative: it adds this one member without removing others who already have the same role or different roles on the task. The taskId, lake, location, and project properties identify which Dataplex task receives the permission.

Grant a role to multiple members at once

When multiple users or service accounts need the same level of access, TaskIamBinding manages all members for a single role as a group.

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

The members property lists all identities that should have this role. TaskIamBinding is authoritative for the specified role: it sets the complete member list, removing any members not in the array. Other roles on the task remain unchanged. You can use TaskIamBinding alongside TaskIamMember as long as they don’t both manage the same role.

Replace the entire IAM policy for a task

Organizations that manage IAM policies centrally often need to set the complete policy in one operation.

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

const admin = gcp.organizations.getIAMPolicy({
    bindings: [{

The policyData property contains the complete IAM policy, typically retrieved from getIAMPolicy or constructed inline. TaskIamPolicy is fully authoritative: it replaces the entire policy, removing any roles or members not included in policyData. This resource conflicts with both TaskIamMember and TaskIamBinding; using them together causes Pulumi to fight over the policy state.

Beyond these examples

These snippets focus on specific IAM management approaches: incremental member addition (TaskIamMember), role-level member management (TaskIamBinding), and complete policy replacement (TaskIamPolicy). They’re intentionally minimal rather than full access control systems.

The examples reference pre-existing infrastructure such as Dataplex tasks (identified by taskId, lake, location, project) and IAM principals (users, service accounts, groups). They focus on configuring permissions rather than provisioning the tasks themselves.

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

Conditional IAM bindings (condition property)
Custom role definitions and formatting
Federated identity configuration
Policy conflict resolution between resource types

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 Dataplex TaskIamMember resource reference for all available configuration options.

Frequently Asked Questions

Resource Selection & Conflicts

What's the difference between TaskIamPolicy, TaskIamBinding, and TaskIamMember?

TaskIamPolicy is authoritative and replaces the entire IAM policy. TaskIamBinding is authoritative for a specific role, managing all members for that role. TaskIamMember is non-authoritative, adding individual members without affecting other members for the same role.

Can I use TaskIamPolicy with TaskIamBinding or TaskIamMember?

No, TaskIamPolicy cannot be used with TaskIamBinding or TaskIamMember because they will conflict over the policy.

Can I use TaskIamBinding and TaskIamMember together?

Yes, but only if they don’t grant privileges to the same role. If they manage the same role, they will conflict.

Identity & Role Configuration

What identity formats can I use for the member parameter?

You can use allUsers, allAuthenticatedUsers, user:{email}, serviceAccount:{email}, group:{email}, domain:{domain}, projectOwner:projectid, projectEditor:projectid, projectViewer:projectid, or federated identities like principal://iam.googleapis.com/....

How do I specify custom roles?

Custom roles must use the full format [projects|organizations]/{parent-name}/roles/{role-name}, for example projects/my-project/roles/my-custom-role.
