Manage GCP Dataplex Entry Group IAM Policies

The gcp:dataplex/entryGroupIamPolicy:EntryGroupIamPolicy resource, part of the Pulumi GCP provider, manages IAM access control for Dataplex entry groups using three distinct approaches: full policy replacement, role-level binding, or individual member grants. This guide focuses on three capabilities: authoritative policy replacement (EntryGroupIamPolicy), role-level member binding (EntryGroupIamBinding), and individual member grants (EntryGroupIamMember).

These resources reference existing entry groups and require project/location context. The examples are intentionally small. Combine them with your own entry group infrastructure and organizational IAM policies.

Replace the entire IAM policy for an entry group

When you need complete control over who can access an entry group, you can set the entire IAM policy at once, replacing any existing permissions.

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.EntryGroupIamPolicy("policy", {
    project: testEntryGroupBasic.project,
    location: testEntryGroupBasic.location,
    entryGroupId: testEntryGroupBasic.entryGroupId,
    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.EntryGroupIamPolicy("policy",
    project=test_entry_group_basic["project"],
    location=test_entry_group_basic["location"],
    entry_group_id=test_entry_group_basic["entryGroupId"],
    policy_data=admin.policy_data)

package main

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

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",
					},
				},
			},
		}, nil)
		if err != nil {
			return err
		}
		_, err = dataplex.NewEntryGroupIamPolicy(ctx, "policy", &dataplex.EntryGroupIamPolicyArgs{
			Project:      pulumi.Any(testEntryGroupBasic.Project),
			Location:     pulumi.Any(testEntryGroupBasic.Location),
			EntryGroupId: pulumi.Any(testEntryGroupBasic.EntryGroupId),
			PolicyData:   pulumi.String(admin.PolicyData),
		})
		if err != nil {
			return err
		}
		return nil
	})
}

            members:
              - user:jane@example.com

The EntryGroupIamPolicy resource is authoritative: it replaces the entire IAM policy on the entry group. The policyData comes from the getIAMPolicy data source, which defines bindings (role-to-members mappings). This approach cannot be used alongside EntryGroupIamBinding or EntryGroupIamMember resources, as they would conflict over policy ownership.

Grant a role to multiple members at once

When multiple users or service accounts need the same level of access, you can bind them all to a single role in one operation.

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

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

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

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

The EntryGroupIamBinding resource is authoritative for a specific role: it sets the complete list of members for that role while preserving other roles in the policy. The members array accepts user accounts, service accounts, groups, and domains. You can use multiple EntryGroupIamBinding resources for different roles, but only one binding per role.

Add a single member to a role incrementally

When you need to grant access to one user without affecting existing permissions, you can add individual members to roles.

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",
});

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")

			EntryGroupId: pulumi.Any(testEntryGroupBasic.EntryGroupId),

		})

        EntryGroupId = testEntryGroupBasic.EntryGroupId,

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

The EntryGroupIamMember resource is non-authoritative: it adds one member to a role without affecting other members. This is the safest option when multiple teams manage access independently. You can combine EntryGroupIamMember with EntryGroupIamBinding resources as long as they don’t grant the same role.

Beyond these examples

These snippets focus on specific IAM management approaches: 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 systems.

The examples reference pre-existing infrastructure such as Dataplex entry groups (testEntryGroupBasic) and GCP project and location configuration. They focus on IAM policy configuration rather than provisioning the underlying entry groups.

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

  • Conditional IAM bindings (condition blocks)
  • Service account impersonation
  • Custom role definitions
  • Audit logging configuration

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 EntryGroupIamPolicy resource reference for all available configuration options.

Frequently Asked Questions

Resource Selection & Conflicts
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 to a role while preserving other members.
Can I use EntryGroupIamPolicy with EntryGroupIamBinding or EntryGroupIamMember?
No, EntryGroupIamPolicy cannot be used alongside EntryGroupIamBinding or EntryGroupIamMember because they will conflict over the policy state.
Can I use EntryGroupIamBinding and EntryGroupIamMember together?
Yes, but only if they manage different roles. Using both for the same role will cause conflicts.
Configuration & Setup
How do I generate the policyData for EntryGroupIamPolicy?
Use the gcp.organizations.getIAMPolicy data source with your desired bindings, then pass its policyData output to the EntryGroupIamPolicy resource.
Which resource should I use to add a single user to a role?
Use EntryGroupIamMember to add individual members without affecting existing members for that role.
Import & Migration
What import formats are supported for EntryGroupIamPolicy?
You can import using: projects/{{project}}/locations/{{location}}/entryGroups/{{entry_group_id}}, {{project}}/{{location}}/{{entry_group_id}}, {{location}}/{{entry_group_id}}, or just {{entry_group_id}}. Missing values are taken from the provider configuration.
