Manage GCP Data Catalog Entry Group IAM Access

The gcp:datacatalog/entryGroupIamMember:EntryGroupIamMember resource, part of the Pulumi GCP provider, grants IAM permissions on Data Catalog entry groups by adding individual members to roles. This resource is deprecated; for new projects, use gcp.dataplex.EntryGroup instead. This guide focuses on three capabilities: non-authoritative member grants, authoritative role bindings, and complete policy replacement.

All examples reference existing entry groups. The examples are intentionally small. Combine them with your own entry group resources and IAM policies.

Grant a single user access to an entry group

When you need to add one user or service account without affecting other permissions, EntryGroupIamMember provides non-authoritative access management.

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

const member = new gcp.datacatalog.EntryGroupIamMember("member", {
    entryGroup: basicEntryGroup.name,
    role: "roles/viewer",
    member: "user:jane@example.com",
});

import pulumi
import pulumi_gcp as gcp

member = gcp.datacatalog.EntryGroupIamMember("member",
    entry_group=basic_entry_group["name"],
    role="roles/viewer",
    member="user:jane@example.com")

package main

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

func main() {
	pulumi.Run(func(ctx *pulumi.Context) error {
		_, err := datacatalog.NewEntryGroupIamMember(ctx, "member", &datacatalog.EntryGroupIamMemberArgs{
			EntryGroup: pulumi.Any(basicEntryGroup.Name),
			Role:       pulumi.String("roles/viewer"),
			Member:     pulumi.String("user:jane@example.com"),
		})
		if err != nil {
			return err
		}
		return nil
	})
}

        Role = "roles/viewer",
        Member = "user:jane@example.com",
    });

});

    properties:

      member: user:jane@example.com

The member property specifies who receives access using IAM identity syntax (user:, serviceAccount:, group:, etc.). The role property defines what permissions they get. This resource adds the member without removing others who already have the same role.

Manage all members for a specific role

When you need to control the complete list of who has a particular role, EntryGroupIamBinding provides authoritative management for that role.

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

const binding = new gcp.datacatalog.EntryGroupIamBinding("binding", {
    entryGroup: basicEntryGroup.name,
    role: "roles/viewer",
    members: ["user:jane@example.com"],
});

import pulumi

        Members = new[]

resources:

    properties:
      entryGroup: ${basicEntryGroup.name}
      role: roles/viewer
      members:
        - user:jane@example.com

The members property lists everyone who should have this role. EntryGroupIamBinding ensures only these members have the role, removing anyone not in the list. Other roles on the entry group remain unchanged.

Replace the entire IAM policy from a data source

Organizations with centralized policies can retrieve a complete policy definition and apply it to entry groups.

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.datacatalog.EntryGroupIamPolicy("policy", {
    entryGroup: basicEntryGroup.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.datacatalog.EntryGroupIamPolicy("policy",
    entry_group=basic_entry_group["name"],
    policy_data=admin.policy_data)

func main() {
	pulumi.Run(func(ctx *pulumi.Context) error {
		admin, err := organizations.LookupIAMPolicy(ctx, &organizations.LookupIAMPolicyArgs{
			Bindings: []organizations.GetIAMPolicyBinding{
				{
					Role: "roles/viewer",
					Members: []string{
						"user:jane@example.com",

		if err != nil {

			PolicyData: pulumi.String(admin.PolicyData),
		})
		if err != nil {
			return err
		}
		return nil
	})
}

using System.Collections.Generic;
using System.Linq;
using Pulumi;
using Gcp = Pulumi.Gcp;

return await Deployment.RunAsync(() => 
{
    var admin = Gcp.Organizations.GetIAMPolicy.Invoke(new()

        Bindings = new[]
        {
            new Gcp.Organizations.Inputs.GetIAMPolicyBindingInputArgs

    var policy = new Gcp.DataCatalog.EntryGroupIamPolicy("policy", new()

        EntryGroup = basicEntryGroup.Name,
        PolicyData = admin.Apply(getIAMPolicyResult => getIAMPolicyResult.PolicyData),
    });

            .policyData(admin.policyData())
            .build());

    }
}

resources:
  policy:
    type: gcp:datacatalog:EntryGroupIamPolicy
    properties:
      entryGroup: ${basicEntryGroup.name}
      policyData: ${admin.policyData}
variables:
  admin:
    fn::invoke:
      function: gcp:organizations:getIAMPolicy
      arguments:
        bindings:
          - role: roles/viewer
            members:
              - user:jane@example.com

The policyData property accepts a complete IAM policy from getIAMPolicy or another source. EntryGroupIamPolicy replaces the entire policy, removing any bindings not included in the new policy. This approach conflicts with EntryGroupIamBinding and EntryGroupIamMember; use only one pattern per entry group.

Beyond these examples

These snippets focus on specific IAM management patterns: non-authoritative member grants, authoritative role bindings, and complete policy replacement. They’re intentionally minimal rather than full access control configurations.

The examples reference pre-existing infrastructure such as Data Catalog entry groups and IAM policy data sources (for policy example). They focus on granting permissions rather than creating the underlying resources.

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

Conditional IAM bindings (condition property)
Cross-project or cross-region references (project, region properties)
Custom role definitions
Service account creation and management

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 EntryGroupIamMember resource reference for all available configuration options.

Frequently Asked Questions

Migration & Deprecation

Should I still use this resource?

The parent resource gcp.datacatalog.EntryGroup is deprecated and will be removed in a future major release. Migrate to gcp.dataplex.EntryGroup instead. See the Dataplex Catalog transition guide for migration steps.

Resource Selection & Conflicts

Which IAM resource should I use?

Choose based on your needs:

gcp.datacatalog.EntryGroupIamPolicy: Authoritative, replaces entire IAM policy
gcp.datacatalog.EntryGroupIamBinding: Authoritative for a specific role, preserves other roles
gcp.datacatalog.EntryGroupIamMember: Non-authoritative, adds a single member to a role while preserving other members

Can I use multiple IAM resources together?

gcp.datacatalog.EntryGroupIamPolicy cannot be used with EntryGroupIamBinding or EntryGroupIamMember as they will conflict. However, EntryGroupIamBinding and EntryGroupIamMember can be used together only if they don’t grant the same role.

Configuration & Identity Formats

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}
Federated identities (e.g., principal://iam.googleapis.com/...)

Do I need to specify project and region?

Both project and region are required but can be automatically parsed from the parent entryGroup identifier or taken from the provider configuration if not explicitly specified.

What properties can't be changed after creation?

All properties are immutable: entryGroup, member, role, project, region, and condition cannot be modified after the resource is created.

Advanced Configuration

How do I specify custom roles?

Custom roles must use the 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.

How do I import an existing IAM member?

Use space-delimited identifiers with the resource path, role, and member identity. For example:

pulumi import gcp:datacatalog/entryGroupIamMember:EntryGroupIamMember editor "projects/{{project}}/locations/{{region}}/entryGroups/{{entry_group}} roles/viewer user:jane@example.com"
