Manage GCP Dataplex Entry Group IAM Access

The gcp:dataplex/entryGroupIamMember:EntryGroupIamMember resource, part of the Pulumi GCP provider, manages IAM permissions for Dataplex EntryGroup resources by granting roles to individual members, groups of members, or replacing the entire policy. This guide focuses on three capabilities: single-member role grants (EntryGroupIamMember), multi-member role bindings (EntryGroupIamBinding), and full policy replacement (EntryGroupIamPolicy).

These resources reference existing EntryGroup resources and require appropriate IAM permissions to modify access policies. The examples are intentionally small. Combine them with your own EntryGroup infrastructure and identity management.

Grant a role to a single member

Most IAM configurations start by granting a specific role to one user or service account, preserving existing role assignments while adding new members 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 specifies the identity receiving access (formats include user:email, serviceAccount:email, group:email, or domain:name). The role property defines the permission level. EntryGroupIamMember is non-authoritative: it adds this member without affecting other members already assigned to the role.

Grant a role to multiple members at once

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

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

The members property accepts a list of identities that all receive the same role. EntryGroupIamBinding is authoritative for the specified role: it replaces the member list for that role but preserves other roles in the policy. This differs from EntryGroupIamMember, which adds one member without affecting others.

Replace the entire IAM policy

Some workflows require complete control over all role assignments, replacing any existing policy with a new authoritative definition.

The policyData property accepts a complete IAM policy document, typically constructed using getIAMPolicy. EntryGroupIamPolicy is fully authoritative: it replaces the entire policy, removing any roles or members not included in the new policy. This resource cannot be used alongside EntryGroupIamBinding or EntryGroupIamMember, as they would conflict over policy ownership.

Beyond these examples

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

The examples reference pre-existing infrastructure such as Dataplex EntryGroup resources and IAM policy documents (for EntryGroupIamPolicy). They focus on configuring IAM permissions 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
  • EntryGroup 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
Which IAM resources can I use together?
EntryGroupIamPolicy cannot be used with EntryGroupIamBinding or EntryGroupIamMember because they’ll conflict over the policy. You can use EntryGroupIamBinding and EntryGroupIamMember together, but only if they don’t grant the same role.
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, replacing all members for that role while preserving other roles. EntryGroupIamMember is non-authoritative and adds a single member to a role without affecting other members.
Identity & Role Configuration
What identity formats can I use for the member property?
You can use allUsers, allAuthenticatedUsers, user:{email}, serviceAccount:{email}, group:{email}, domain:{domain}, projectOwner/Editor/Viewer:{projectid}, or federated identities like principal://iam.googleapis.com/....
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 Behavior
What properties are immutable after creation?
All properties are immutable: entryGroupId, location, member, project, and role. You must recreate the resource to change any of these.
How do I import existing IAM resources?
Use space-delimited identifiers. For EntryGroupIamMember, specify the resource identifier, role, and member identity. For EntryGroupIamBinding, specify the resource identifier and role. For EntryGroupIamPolicy, specify only the resource identifier.
