Manage GCP Dataplex Zone IAM Bindings

The gcp:dataplex/zoneIamBinding:ZoneIamBinding resource, part of the Pulumi GCP provider, manages IAM role bindings for Dataplex zones by granting a specific role to a list of members. This guide focuses on two capabilities: authoritative role binding for multiple members and non-authoritative member addition.

ZoneIamBinding is one of three IAM resources for Dataplex zones. It’s authoritative for a given role, meaning it replaces all members for that role while preserving other roles. ZoneIamMember is non-authoritative, adding individual members without affecting others. ZoneIamPolicy is fully authoritative and cannot be used alongside ZoneIamBinding or ZoneIamMember. The examples are intentionally small. Combine them with your own Dataplex zones and access requirements.

Grant a role to multiple members

Teams managing zones often need to assign the same role to multiple users or service accounts at once, such as giving viewer access to a data team.

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

const binding = new gcp.dataplex.ZoneIamBinding("binding", {
    project: example.project,
    location: example.location,
    lake: example.lake,
    dataplexZone: example.name,
    role: "roles/viewer",
    members: ["user:jane@example.com"],
});

import pulumi
import pulumi_gcp as gcp

binding = gcp.dataplex.ZoneIamBinding("binding",
    project=example["project"],
    location=example["location"],
    lake=example["lake"],
    dataplex_zone=example["name"],
    role="roles/viewer",
    members=["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.NewZoneIamBinding(ctx, "binding", &dataplex.ZoneIamBindingArgs{
			Project:      pulumi.Any(example.Project),
			Location:     pulumi.Any(example.Location),
			Lake:         pulumi.Any(example.Lake),
			DataplexZone: pulumi.Any(example.Name),
			Role:         pulumi.String("roles/viewer"),
			Members: pulumi.StringArray{
				pulumi.String("user:jane@example.com"),
			},
		})
		if err != nil {
			return err
		}
		return nil
	})
}

    var binding = new Gcp.DataPlex.ZoneIamBinding("binding", new()
    {
        Project = example.Project,
        Location = example.Location,
        Lake = example.Lake,
        DataplexZone = example.Name,
        Role = "roles/viewer",
        Members = new[]
        {
            "user:jane@example.com",

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

The role property specifies which IAM role to grant (e.g., “roles/viewer”). The members array lists all identities that receive this role; ZoneIamBinding replaces any existing members for this role. The dataplexZone, lake, location, and project properties identify which zone to configure.

Add a single member to a role

When onboarding individual users or granting access to specific service accounts, you can add members one at a time without affecting others.

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

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

import pulumi
import pulumi_gcp as gcp

member = gcp.dataplex.ZoneIamMember("member",
    project=example["project"],
    location=example["location"],
    lake=example["lake"],
    dataplex_zone=example["name"],
    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.NewZoneIamMember(ctx, "member", &dataplex.ZoneIamMemberArgs{
			Project:      pulumi.Any(example.Project),
			Location:     pulumi.Any(example.Location),
			Lake:         pulumi.Any(example.Lake),
			DataplexZone: pulumi.Any(example.Name),
			Role:         pulumi.String("roles/viewer"),
			Member:       pulumi.String("user:jane@example.com"),
		})
		if err != nil {
			return err
		}
		return nil
	})
}

using System.Collections.Generic;

using Gcp = Pulumi.Gcp;

return await Deployment.RunAsync(() => 
{
    var member = new Gcp.DataPlex.ZoneIamMember("member", new()
    {
        Project = example.Project,
        Location = example.Location,
        Lake = example.Lake,
        DataplexZone = example.Name,
        Role = "roles/viewer",
        Member = "user:jane@example.com",
    });

});

ZoneIamMember is non-authoritative: it adds a single member to a role without removing existing members. Use member (singular) instead of members (array). This approach works well when multiple teams manage access independently, but avoid using ZoneIamMember and ZoneIamBinding for the same role, as they will conflict.

Beyond these examples

These snippets focus on specific IAM binding features: role-based access control and authoritative vs non-authoritative member management. They’re intentionally minimal rather than full access control configurations.

The examples reference pre-existing infrastructure such as Dataplex zones and lakes, and a GCP project with Dataplex API enabled. They focus on configuring IAM bindings rather than provisioning the underlying Dataplex resources.

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

Conditional IAM bindings (condition property)
Policy-level management (ZoneIamPolicy resource)
Custom role definitions
Federated identity configuration

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

Frequently Asked Questions

Resource Selection & Conflicts

Can I use ZoneIamPolicy with ZoneIamBinding or ZoneIamMember?

No, gcp.dataplex.ZoneIamPolicy cannot be used with gcp.dataplex.ZoneIamBinding or gcp.dataplex.ZoneIamMember because they will conflict over the policy. Use ZoneIamPolicy alone for full control, or use ZoneIamBinding and ZoneIamMember together.

Can I use ZoneIamBinding and ZoneIamMember together?

Yes, but only if they don’t grant privileges to the same role. Each gcp.dataplex.ZoneIamBinding manages all members for a specific role, so mixing with ZoneIamMember for that same role will cause conflicts.

Which IAM resource should I use for managing Dataplex Zone permissions?

Choose based on your needs: gcp.dataplex.ZoneIamPolicy replaces the entire policy (authoritative), gcp.dataplex.ZoneIamBinding manages all members for a specific role (preserves other roles), and gcp.dataplex.ZoneIamMember adds individual members (preserves other members for the role).

Configuration & Formats

How do I specify custom roles in ZoneIamBinding?

Custom roles must use the format [projects|organizations]/{parent-name}/roles/{role-name}. For example, projects/my-project/roles/customRole or organizations/my-org/roles/customRole.

What member identity formats are supported?

The members array supports: allUsers, allAuthenticatedUsers, user:{email}, serviceAccount:{email}, group:{email}, domain:{domain}, projectOwner:projectid, projectEditor:projectid, projectViewer:projectid, and federated identities like principal://iam.googleapis.com/....

Resource Properties

What properties can't be changed after creating a ZoneIamBinding?

The role, dataplexZone, lake, location, project, and condition properties are all immutable. You must recreate the resource to change any of these values.
