Manage GCP Dataplex Zone IAM Policies

The gcp:dataplex/zoneIamPolicy:ZoneIamPolicy resource, part of the Pulumi GCP provider, manages IAM policies for Dataplex zones, controlling who can access and modify zone resources. This guide focuses on three approaches: authoritative policy replacement, role-level member binding, and individual member grants.

Dataplex zones exist within lakes, which exist within projects and locations. The examples reference existing zones by their full path. Choose your IAM resource type carefully: ZoneIamPolicy replaces the entire policy, ZoneIamBinding manages all members for one role, and ZoneIamMember adds individual members without affecting others.

Replace the entire IAM policy for a zone

When you need complete control over zone access, set the entire IAM policy at once.

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.ZoneIamPolicy("policy", {
    project: example.project,
    location: example.location,
    lake: example.lake,
    dataplexZone: example.name,
    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.ZoneIamPolicy("policy",
    project=example["project"],
    location=example["location"],
    lake=example["lake"],
    dataplex_zone=example["name"],
    policy_data=admin.policy_data)

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

					Role: "roles/viewer",

			Project:      pulumi.Any(example.Project),

			Lake:         pulumi.Any(example.Lake),
			DataplexZone: pulumi.Any(example.Name),

		})

	})

            members:
              - user:jane@example.com

ZoneIamPolicy is authoritative: it replaces any existing policy on the zone. The policyData comes from the getIAMPolicy data source, which defines bindings (role-to-members mappings). This approach gives you complete control but requires listing all desired permissions. Use it when you want to ensure no unexpected access exists.

Grant a role to multiple members at once

When multiple users or service accounts need the same role, bind them together in one resource.

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

const binding = new gcp.dataplex.ZoneIamBinding("binding", {

			Location:     pulumi.Any(example.Location),

			Role:         pulumi.String("roles/viewer"),

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

ZoneIamBinding is authoritative for the specified role but preserves other roles in the policy. The members array lists all identities that should have this role. If you add or remove members from this list, Pulumi updates the binding accordingly. Other roles on the zone remain unchanged.

Add a single member to a role incrementally

When you need to grant access to one user without affecting others, add them individually.

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,

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

ZoneIamMember is non-authoritative: it adds one member to a role without removing existing members. Use this when multiple teams manage access independently, or when you want to grant access without knowing who else has the same role. The member property takes a single identity string.

Beyond these examples

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

The examples reference pre-existing infrastructure such as Dataplex zones identified by project, location, lake, and zone name. They focus on IAM policy configuration rather than provisioning the zones themselves.

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

Conditional IAM bindings (condition blocks)
Service account impersonation
Custom role definitions
IAM policy retrieval (data source usage)

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 Zone IAM Policy resource reference for all available configuration options.

Frequently Asked Questions

Resource Selection & Conflicts

What resources conflict with ZoneIamPolicy?

ZoneIamPolicy cannot be used with ZoneIamBinding or ZoneIamMember because they will conflict over the policy configuration.

Can I use ZoneIamBinding with ZoneIamMember?

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

Which IAM resource should I use for Dataplex Zone?

Choose based on your needs:

ZoneIamPolicy: Authoritative, replaces the entire policy
ZoneIamBinding: Authoritative for a specific role, preserves other roles
ZoneIamMember: Non-authoritative, adds a single member while preserving others

Configuration & Setup

How do I generate the policyData for ZoneIamPolicy?

Use the gcp.organizations.getIAMPolicy data source to generate policyData, as shown in the example.

What identifiers are required to bind IAM policy to a zone?

You need dataplexZone, lake, location, and project. The location and project can be parsed from the parent resource identifier or taken from provider configuration if not specified.

Import & Migration

What formats can I use when importing a Dataplex Zone IAM resource?

Four formats are supported:

projects/{{project}}/locations/{{location}}/lakes/{{lake}}/zones/{{name}}
{{project}}/{{location}}/{{lake}}/{{name}}
{{location}}/{{lake}}/{{name}}
{{name}}

Variables not in the import command are taken from provider configuration.

How do I import a custom IAM role?

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