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 by granting a specific role to a list of members. This guide focuses on two capabilities: granting roles to multiple members and adding individual members incrementally.

This resource is authoritative for a given role, meaning it replaces all members for that role. It’s one of three IAM resources for EntryGroups; EntryGroupIamPolicy cannot be used alongside Binding or Member resources, as they will conflict. The examples are intentionally small. Combine them with your own EntryGroup resources and access requirements.

Grant a role to multiple members at once

Teams managing EntryGroup access often need to assign the same role to multiple users or service accounts simultaneously, such as giving viewer access to an entire team.

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 = new[]
        {

    properties:

      entryGroupId: ${testEntryGroupBasic.entryGroupId}
      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; each entry uses a specific format like “user:jane@example.com” for individual users or “serviceAccount:app@project.iam.gserviceaccount.com” for service accounts. This binding is authoritative: it replaces any existing members for this role on the EntryGroup.

Add a single member to a role incrementally

When onboarding individual users or service accounts, you can add them one at a time without affecting other members who already have access.

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

const member = new gcp.dataplex.EntryGroupIamMember("member", {
    project: testEntryGroupBasic.project,

    role: "roles/viewer",
    member: "user:jane@example.com",
});

member = gcp.dataplex.EntryGroupIamMember("member",

    role="roles/viewer",
    member="user:jane@example.com")

package main

		})
		if err != nil {
			return err
		}
		return nil
	})

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

The member property (singular) specifies one identity to add to the role. Unlike EntryGroupIamBinding, this resource is non-authoritative: it preserves other members already assigned to the role. Use this when you need to grant access incrementally without managing the complete member list.

Beyond these examples

These snippets focus on specific IAM binding features: role-based access control and bulk and incremental member assignment. They’re intentionally minimal rather than full access management solutions.

The examples reference pre-existing infrastructure such as Dataplex EntryGroup resources and a GCP project with Dataplex API enabled. They focus on configuring IAM bindings rather than provisioning EntryGroups themselves.

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 details

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 Conflicts & Compatibility

Why am I getting IAM policy conflicts between my resources?

EntryGroupIamPolicy cannot be used with EntryGroupIamBinding or EntryGroupIamMember because they will fight over the policy. Use either EntryGroupIamPolicy alone (authoritative) or use EntryGroupIamBinding/EntryGroupIamMember together.

Can I use EntryGroupIamBinding and EntryGroupIamMember together?

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

Resource Selection

What's the difference between EntryGroupIamPolicy, EntryGroupIamBinding, and EntryGroupIamMember?

EntryGroupIamPolicy is authoritative and replaces the entire IAM policy. EntryGroupIamBinding is authoritative for a specific role, preserving other roles. EntryGroupIamMember is non-authoritative, adding a single member while preserving other members for that role.

Configuration & Syntax

What member identity formats are supported?

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

How do I specify custom IAM roles?

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

Import & Management

How do I import EntryGroup IAM resources?

Import syntax varies by resource type: EntryGroupIamMember requires space-delimited “resource role member”, EntryGroupIamBinding requires “resource role”, and EntryGroupIamPolicy requires just the resource identifier. Custom roles need their full name during import.
