Manage GCP Dataplex Entry Group IAM Access

The gcp:dataplex/entryGroupIamMember:EntryGroupIamMember resource, part of the Pulumi GCP provider, grants IAM permissions on Dataplex EntryGroup resources by adding individual members to roles. This guide focuses on three approaches: single-member grants, multi-member bindings, and full policy replacement.

Three related resources manage EntryGroup IAM: EntryGroupIamMember adds one member non-authoritatively, EntryGroupIamBinding manages all members for a role authoritatively, and EntryGroupIamPolicy replaces the entire policy. Mixing Policy with Binding or Member causes conflicts. The examples are intentionally small. Combine them with your own EntryGroup resources and organizational IAM structure.

Grant a role to a single member

Most IAM configurations add one user or service account to a role, preserving existing assignments while expanding access incrementally.

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
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 (
	"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.NewEntryGroupIamMember(ctx, "member", &dataplex.EntryGroupIamMemberArgs{
			Project:      pulumi.Any(testEntryGroupBasic.Project),
			Location:     pulumi.Any(testEntryGroupBasic.Location),
			EntryGroupId: pulumi.Any(testEntryGroupBasic.EntryGroupId),
			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

The member property identifies who receives access using formats like “user:jane@example.com” or “serviceAccount:app@project.iam.gserviceaccount.com”. The role property specifies the permission set to grant. This resource is non-authoritative: it adds the member without removing others already assigned to the role.

Grant a role to multiple members at once

When several users or service accounts need identical permissions, binding them together ensures they’re managed as a group.

      members:

The EntryGroupIamBinding resource takes a members array instead of a single member string. This resource is authoritative for the specified role: it sets the complete member list, removing any members not in the array. Other roles on the EntryGroup remain unchanged.

Replace the entire IAM policy

Organizations managing IAM centrally often set the complete policy in one operation, replacing any existing configuration.

The EntryGroupIamPolicy resource uses policyData from the getIAMPolicy data source, which defines all role bindings at once. This resource is fully authoritative: it replaces the entire IAM policy for the EntryGroup. It cannot be used alongside EntryGroupIamBinding or EntryGroupIamMember because they will conflict over policy ownership.

Beyond these examples

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

The examples reference pre-existing infrastructure such as Dataplex EntryGroup resources and GCP project and location configuration. They focus on IAM binding configuration rather than provisioning the EntryGroups themselves.

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

Conditional IAM bindings (condition property)
Custom role definitions
Service account creation and management
EntryGroup resource provisioning

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

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, managing all members for that role while preserving other roles. EntryGroupIamMember is non-authoritative, adding individual members without affecting other members for the same role.

Can I mix EntryGroupIamPolicy with other IAM resources?

No, EntryGroupIamPolicy cannot be used with EntryGroupIamBinding or EntryGroupIamMember as they will conflict over policy management.

Can I use EntryGroupIamBinding and EntryGroupIamMember together?

Yes, but only if they don’t grant privileges to the same role. Using both for the same role will cause conflicts.

IAM Configuration

What member identity formats are supported?

Supported formats include allUsers, allAuthenticatedUsers, user:{email}, serviceAccount:{email}, group:{email}, domain:{domain}, projectOwner/Editor/Viewer:{projectid}, and federated identities using principal:// format.

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.

Resource Properties & Immutability

What properties can't be changed after creation?

All properties are immutable: entryGroupId, location, member, project, role, and condition. Changes require resource replacement.
