Manage GCP Dataplex Entry Group IAM Bindings

The gcp:dataplex/entryGroupIamBinding:EntryGroupIamBinding resource, part of the Pulumi GCP provider, manages IAM role bindings for Dataplex EntryGroups. It controls which members (users, service accounts, groups) have specific roles on an EntryGroup. This guide focuses on two capabilities: authoritative role binding to multiple members and non-authoritative single-member additions.

IAM bindings reference existing EntryGroup resources and require appropriate IAM permissions. The examples are intentionally small. Combine them with your own EntryGroup infrastructure and identity management.

Grant a role to multiple members at once

When managing team access, you often need to assign the same role to multiple users or service accounts simultaneously.

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

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

import pulumi
import pulumi_gcp as gcp

binding = gcp.dataplex.EntryGroupIamBinding("binding",
    project=test_entry_group_basic["project"],
    location=test_entry_group_basic["location"],
    entry_group_id=test_entry_group_basic["entryGroupId"],
    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.NewEntryGroupIamBinding(ctx, "binding", &dataplex.EntryGroupIamBindingArgs{
			Project:      pulumi.Any(testEntryGroupBasic.Project),
			Location:     pulumi.Any(testEntryGroupBasic.Location),
			EntryGroupId: pulumi.Any(testEntryGroupBasic.EntryGroupId),
			Role:         pulumi.String("roles/viewer"),
			Members: pulumi.StringArray{
				pulumi.String("user:jane@example.com"),
			},
		})
		if err != nil {
			return err
		}
		return nil
	})
}

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

The EntryGroupIamBinding resource is authoritative for the specified role. The members array lists all identities that should have this role; any existing members not in the list are removed. The role property specifies the IAM role (predefined or custom), and entryGroupId, location, and project identify the target EntryGroup.

Add a single member to a role incrementally

When onboarding individual users, you can add them to a role without affecting existing members.

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

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

import pulumi_gcp as gcp

member = gcp.dataplex.EntryGroupIamMember("member",
    project=test_entry_group_basic["project"],
    location=test_entry_group_basic["location"],
    entry_group_id=test_entry_group_basic["entryGroupId"],
    role="roles/viewer",
    member="user:jane@example.com")

package main

import (

func main() {

			return err

		return nil
	})

        EntryGroupId = testEntryGroupBasic.EntryGroupId,
        Role = "roles/viewer",

      member: user:jane@example.com

The EntryGroupIamMember resource is non-authoritative. It adds a single member to a role while preserving other members already assigned to that role. Use member (singular) instead of members (plural) to specify one identity. This approach works well for incremental access grants where you don’t want to manage the complete member list.

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 EntryGroup resources and a Google Cloud project with Dataplex enabled. They focus on configuring IAM bindings rather than provisioning the underlying EntryGroups.

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

Conditional IAM bindings (condition property)
Policy-level management (EntryGroupIamPolicy 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 EntryGroupIamBinding resource reference for all available configuration options.

Frequently Asked Questions

Resource Selection & Conflicts

Which IAM resource should I use to manage EntryGroup permissions?

Choose based on your needs: EntryGroupIamPolicy for complete policy control (replaces all existing permissions), EntryGroupIamBinding to manage all members for a specific role (preserves other roles), or EntryGroupIamMember to add individual members to a role (preserves other members).

Can I use EntryGroupIamPolicy with EntryGroupIamBinding or EntryGroupIamMember?

No, EntryGroupIamPolicy cannot be used with EntryGroupIamBinding or EntryGroupIamMember because they will conflict over policy management. However, EntryGroupIamBinding and EntryGroupIamMember can coexist if they manage different roles.

Configuration & Syntax

How do I specify custom roles for EntryGroup IAM bindings?

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

What member identity formats are supported?

Supported formats include: allUsers, allAuthenticatedUsers, user:{email}, serviceAccount:{email}, group:{email}, domain:{domain}, projectOwner:{projectid}, projectEditor:{projectid}, projectViewer:{projectid}, and federated identities like principal://iam.googleapis.com/locations/global/workforcePools/example-contractors/subject/joe@example.com.

Import & Migration

How do I import an existing EntryGroupIamBinding?

Use space-delimited identifiers with the resource path and role:

pulumi import gcp:dataplex/entryGroupIamBinding:EntryGroupIamBinding editor "projects/{{project}}/locations/{{location}}/entryGroups/{{entry_group_id}} roles/viewer"

. For custom roles, use the full role path.
