Manage GCP Dataplex EntryType IAM Access

The gcp:dataplex/entryTypeIamMember:EntryTypeIamMember resource, part of the Pulumi GCP provider, manages IAM access to Dataplex EntryType resources by granting roles to individual members without affecting other role assignments. This guide focuses on three capabilities: single-member role grants, multi-member role bindings, and authoritative policy replacement.

Dataplex provides three IAM resources for EntryTypes: EntryTypeIamMember (non-authoritative, adds one member), EntryTypeIamBinding (authoritative for a role, manages all members), and EntryTypeIamPolicy (authoritative for all roles, replaces entire policy). These resources cannot be mixed for the same EntryType without conflicts. The examples are intentionally small. Combine them with your own EntryType resources and access requirements.

Grant a role to a single member

Most access grants start by adding one user or service account to a role, preserving existing assignments.

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

const member = new gcp.dataplex.EntryTypeIamMember("member", {
    project: testEntryTypeBasic.project,
    location: testEntryTypeBasic.location,
    entryTypeId: testEntryTypeBasic.entryTypeId,
    role: "roles/viewer",
    member: "user:jane@example.com",
});

    location=test_entry_type_basic["location"],
    entry_type_id=test_entry_type_basic["entryTypeId"],
    role="roles/viewer",
    member="user:jane@example.com")

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

The member property specifies who receives access using IAM identity formats (user:, serviceAccount:, group:, domain:). The role property defines the permission level. This resource is non-authoritative: it adds the member without removing others who already have the role.

Grant a role to multiple members at once

When several identities need the same role, binding them together ensures they’re managed as a group.

The members property accepts a list of IAM identities. This resource is authoritative for the specified role: it replaces all members for that role. Other roles on the EntryType remain unchanged.

Organizations managing policies externally can replace all role bindings in one operation.

The policyData property accepts a complete IAM policy document from getIAMPolicy. This resource is fully authoritative: it replaces all roles and members on the EntryType. The bindings array in the policy defines all role assignments.

Beyond these examples

These snippets focus on specific IAM management approaches: incremental member grants, role binding management, and authoritative policy replacement. They’re intentionally minimal rather than complete access control configurations.

The examples reference pre-existing infrastructure such as Dataplex EntryType resources (testEntryTypeBasic) and a GCP project with Dataplex enabled. They focus on IAM configuration rather than EntryType provisioning.

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

Conditional IAM bindings (condition property)
Custom role definitions
Policy retrieval via data sources
Mixed use of Policy, Binding, and Member resources

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 EntryTypeIamMember resource reference for all available configuration options.

Frequently Asked Questions

Resource Conflicts & Compatibility

Why are my EntryType IAM resources conflicting?

EntryTypeIamPolicy cannot be used with EntryTypeIamBinding or EntryTypeIamMember because they manage policies differently and will conflict. Choose either the authoritative EntryTypeIamPolicy or the incremental EntryTypeIamBinding/EntryTypeIamMember approach.

Can I use EntryTypeIamBinding and EntryTypeIamMember together?

Yes, but only if they don’t grant privileges to the same role. Each role must be managed by only one resource type to avoid conflicts.

Resource Selection

What's the difference between EntryTypeIamPolicy, EntryTypeIamBinding, and EntryTypeIamMember?

Three management approaches with different scopes:

EntryTypeIamPolicy: Authoritative for entire policy (replaces all existing bindings)
EntryTypeIamBinding: Authoritative per role (manages all members for one role, preserves other roles)
EntryTypeIamMember: Non-authoritative (adds individual members without affecting others)

Which IAM resource should I use to add a single user without affecting existing permissions?

Use EntryTypeIamMember, which is non-authoritative and preserves existing members for the role.

IAM Configuration

What member identity formats are supported?

Supported formats include:

allUsers / allAuthenticatedUsers: Public or authenticated access
user:{email}: Specific Google account (e.g., user:jane@example.com)
serviceAccount:{email}: Service account
group:{email}: Google group
domain:{domain}: All users in a G Suite domain
projectOwner/Editor/Viewer:{projectid}: Project-level roles
Federated identities: Workload/workforce identity pools (see Principal identifiers documentation)

How do I specify custom IAM roles?

Custom roles must use the format [projects|organizations]/{parent-name}/roles/{role-name} (e.g., projects/my-project/roles/my-custom-role).

What properties are immutable after creation?

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

Common Tasks

How do I grant a role to multiple users?

Use EntryTypeIamBinding with a members array containing all identities (e.g., ["user:jane@example.com", "user:john@example.com"]) for the specified role.
